Those are pretty good amps, channel 2 is the slo hi-gain thing. these cheap amps now days though and what you'd find at the yard/garage sale are full of them damn opamps/ICs that don't sound that good, 4560s/704s and few others...boosted don't sound that great, probaly sound like you're Stereo Lol
I would like to do this stuff. I toted around two amplifiers for years. They worked but lot of static. They were from the army.
I truly cannot believe how much I've learned Brad. This vid proves you are the class of UA-cam when it comes to tube based audio. Man this was impressive.
Hats off to Tony on this one. Nice builds and nice guy as well. I've learned a lot from him.
The Guitologist I had a guy ask me do I know how to bias Tubes because I inquired about a job. I answered by using different caps and resistors (filtering frequencies). The company Cary Audio sells tube amps (class A) for over $10,000!
This video proved that I was right. I haven't done troubleshooting any tubes since I was in the Army in 1979 as a Radar repairman, although I am back into buying and doing repairs on Audiophile equipment. Cheers for you Tand everyone else who watches this channel.

As a regular viewer and full time tech this upload is by far my favorite.. it’s downloaded and probably will listen to it a dozen times...
I glad i'm not the only one who has something against 90 degree angles. Great point to point construction.
Thanks for the informative and entertaining video, Brad and Tony!
Man, that was awesome! Those amps sound KILLER! Thanks to both of you for taking the time to make this. I'm finally getting to the point that I can follow about 90% of what you're talking about. I still have a long way to go, but I'm getting there.
Getting one of Tony’s amps. The last amp y’all looked at that is all P to P wired that is a single ended and with a 6V6 as the output tube. He is finishing the amp for me as I am writing this. He obviously knows his stuff. I use to service and repair guitar amps until I broke my neck in 1999. You do a great job and always enjoy your videos. Keep up the good work. I’d love to meet you one day. Sincerely, David Blackmon
Awesome, David. Glad it's finding a deserving home.
Its cool to be the fly on the wall, listening to techs talk about amps and how you modify and replace components! Thanks man ,way cool.
There was probably another 30 minutes of footage I had to edit down for time reasons. I might post some of that stuff up later.
The Guitologist Thanks again Brad.Merry Christmas to you and your family.!PS tell you bud Tony his amps sound bitchen.And they all looked good too!
Thanks Bob. He'll see your comment, I'm sure. Merry Christmas to you too!
Right on Bob! Merry Xmas to you and yours!
Volition Amps Great job Tony , its like you know exactly what to tweak, in order to get your great sound .Thanks again.Look forward to your next creations.
Another great video, wishing you all a Merry Christmas.
You too, Percy. Merry Christmas.
I don't even own a soldering iron and I watched this whole thing. Hats off to you.
Very impressive work Brad keep the videos coming learning a lot ty
Great video, loved to hear the thought process going into his work. You did a very good job interviewing.
Glad you liked the format. It was an experiment for me and I think it came out ok. I might do more like it in the future if other builders or techs want to come on the show.
Here's another video demo I did of a Volition Advocate model a few years ago. I forgot all about this video: ua-cam.com/video/sIVnTa3hQSY/v-deo.html
Thank you for posting that. Learned a lot, and I love the little rusty amp!
Awesome talk and demo bud, thanks! Good insight into the post phase gain and cool switching options. Nice stuff, Kudos to you Brad and to Volition!
Beautiful work, Tony. Old school Hiwatt quality.
I don't understand any of this, but I like listening to it! Thanks Brad.
Thanks for watching Steve. Glad to have ya.
A single ended 6v6 amp will always bring a tear to my eye.that amp sound great!
I love that one too. My fav of the three.
Thanks for another one! I dig that Charvel, man. I had a similar one back in the 90s.
An hour well spent watching this brad & tony, if pcb`s & transistors represent an electronic invasion of the body snatchers, you two represent "the resistance"in the crusade for valve
circuit fidelity, i can watch this again a few times, cool stuff,
... thanks Brad, really enjoyed this video ... I dig it when you're with a guest yacking about amps!
Yeah, this was a fun one for me. I always learn from Tony.
I learned a lot from this video i could listen to talk like this all day.
Very nice builds
Nice vid Brad and Merry Christmas!
A different flavor of video. Very cool and interesting. Thanks!
Thanks, Jim!
I am sure a lot of nerds like me would love to see Tony back on the channel again. I still have the single 6V6 class a amplifier that was on your channel along with two of his other amps. His knowledge of guitar amps is so extensive.
Good stuff Brad and Tony!
Beautiful work and his amps sound great.
Great video Brad, a lot to learn by exploring these different amps .
I learned a few things in this video. Tony's ideas on paralleling stages to limit noise is something I had not really considered, and also his use of that Jet City loop board seems like a nice way to add a loop cheaply.
Nice video. Learned a lot. Nice work.
That's so cool! Loving it!
You need to show Rusty to Uncle Doug! I bet his Rusty would enjoy it a lot 🐕
Good call. I bet it would pass the sniff test.
Great video! I love your Charvel and also the Warriors shirt!
Wow Tony does really nice wiring such clean work love it!
Yes he does. Well thought out...quiet layouts.
@@TheGuitologist You can tell he's passionate about his work, by his wiring.
That's the best wiring layout I've ever seen
Kinda cool that he put the clipping circuit in, for someone like me to experiment with and find out how I feel about it, but it can be completely bypassed (unlike a few of the later 800's that had the clipping diodes sort of snuck in there), so when it ultimately underwhelms me, I can just flip a switch and go back to an all tube signal path.
Yeah, having that stuff is nice for some styles of music, but you're right, being able to switch it off when you need to is nice.
And the thing is, if what you want is high-gain with lots of clarity and definition, you really do need to just add another gain stage, there's no shortcut that won't lead to some kind of fuzzy over-compressed dirt. A JCM800 with the original Soldano "hot-mod" (not the one that replaces V1 with a 6K11 triple-triode, the one that just adds another 12ax7) and a fairly warm and middy cabinet (800 has a bit of scoop to it) and there is no style of metal that can't be played through that. There are more "modern" amps with 6 or even 8 stages between the input and the master volume, but they are all tube, and they will get you dirtier than you'd ever need to be without sacrificing clarity. It's like each individual stage is doing less of the clipping, and therefor allowed to retain more definition. The diode-clipping circuit is good for very specific lead applications (and I guess rhythm too if you're a smashing pumpkin), but the best dirty rhythm tone still comes from all tube preamp stages cascaded one into the next. I'm thinking of building a preamp using a very basic gain stage from a tube manual, but then cascading like 5 12AU7's, 10 low-gain triode stages, just to see how correct my hypothesis is. I think that if you have two preamps, one with 4 stages and the gain maxed, the other with 8 stages and the gain set lower, (all else being equal or similar) you should be able to get the same amount of total distortion out of the latter with more attack and clarity. I could be wrong, it could be a matter of tone-shaping off the first stage, but it seems just logical to me.
Another super quality video, thank you so much Brad! Another example how this is a real "Super Site" for tube amplification information and general good entertaining fun! Thanks for all the cool links too Brad, I'll take all you have. I really seem to learn a lot going through links. It's usually really great info.
just love the ohms impedance switch... it gives you versatility on your speaker type and your speaker array...
This video was fascinating mate! What a great discussion you & Tony had. Excellent work! So amp garage is up & working again that's great I'll try em again then. Previously my computers wouldn't let me go there with all the virus warnings. Cool!
well learned a lot about amps thank you for sharing
Very interesting video,thanks guys !
Tony seems cool and knows his stuff. I don't believe anyone would think any of the 3 amps he brought over looked sloppy inside.. Very nice work indeed, and all 3 amp sounded great.. I really liked the amp with the 2 small terminal boards running in parallel. Easy to change parts and great heat dissipation as well.. Great video Brad....
Yeah man, Tony's great. I had a good time. Thanks for hanging out with us.
It was great, I wish It was longer! I know, you know what your doing with amps, but Tony seems to know everything, and explains things in a easy to digest method.. You guys touched on the "tone cap" subject a bit, and I'm curios to know what you think about them. I know the signal caps you use, and have used them myself. I tend to purchase slightly more expensive caps (middle of the road type), as I mostly build or repair amps for myself, but have never purchased the really expensive type. I have swapped out Orange drop caps with 50 yr old ceramic disks to see if I could hear a difference...and honestly I couldn't. Are techs or builders just telling people you need expensive caps just to charge more money? But some people/techs swear they make a difference... some people even leave leaky Astron caps in the signal cause they swear they "sound" better. The only thing I can think is the caps are leaking and throwing off the bias of the next pre-amp stage, making it clip earlier... What are your thought's on the subject? Or is this a good idea for an entire video? Maybe some more videos with Tony, his Amplifiers are outstanding and I'm sure he appreciates the exposure to all your viewer's. Thanks for taking the time to read all this... Merry Christmas to you and your family Brad, Take care, Tom
Nice sounding amps. Good playing Guitar man. I prefer a combo but of those heads number 3 sounded good to me.
Thanks man. I agree about number 3. I think it sat with my style of playing best. Just had something there that was magical, I thought. When i was done playing that one, I told Tony it was my fav.
This build is next level very clean job
Really liked this video and Tonys work, knowledge and understanding is top flite. I would be interested on his take on wedging reverb into his builds.
Oh Yeah, this Rusty Amp is incredible, congratulation for this great idea, I might do somthing like this next. Now I'm working on my third Lemmy Bass Amp. After "Murder One" an "Marsha" I'm building a replica of "Killer" based on a Marshall JCM 2000 TSL with my 1992Lem eyletboard, wich looks almsot like your board, just a with a bit more (JMP) oldscool look and I think we are kindred spirits. I love the JMP 800 Mainstage and for quiet hours (because of my neighours) I'm using this post phaseinverter master volume too. Thanks for that, keep on rocking and all the best wishes to you Mr. Guitologist and to you Mr. Tony Dorris, you made my sunday !
Great informative video!!! absolutely fascinating!
Awesome video and yes it was aliens.
That last amp featured was my fave the drive was sweet.
richard Turk my fav too. Sat really well with the Tele.
Great post!
I now own the Tetanus 50(AKA Rustbucket) Loving this amp! Great cleans! Awesome dirt!
Congrats, Jeff. You have a killer amp.
All great sounding amps but I like the last amp the best.... Great Vid Brad!
Agreed. That last amp really had something special that jibed with that Tele. Perfect Telecaster amp.
Also thumbs up for Merlin. Best books you will ever get.
His website has a TON of useful info was well. He is pretty much THE guy all builders look to.
great job guys i learned a lot.
Thanks Richard. Glad you enjoyed the show.
Great video!
Danelectro weren't the only ones. The chassis out of my '67 Vox Pathfinder is obviously a re-purposed shop sign or something. It still has traces of writing on it :-)
Brad & Tony Toni Tone!! You guys need to make this a regular scheduled gathering!! You two really play off each others knowledge..Nice vijeo!!
Thanks, Abe. I had a great time with Tony. It was nice catching up and glad you guys got to hang out with us.
WOW! WOW! That Volition amp is the greatest amp I've ever seen! It's quiet as hell and easy to work on. I'd love to have one of those! Even the old rusty one is great! Did not know that about metal film resistors compared with carbon comp resistors. Learned something. Damn, and I thought my Crate 150 was great.
Love it!
As some one who is going to build a tube amp one day, I love these technique videos from you.
Happy building! If you get stuck, be sure to check out the Amp Garage forum where Tony is a member.

Kudos on highlighting "corksniffing" on coupling caps.
There's a lot of it around. Don't get me wrong, there are surely quality differences separating some caps, and they might last longer as a consequence, but it's hard to tell which will survive best long term without a time machine.
True, but the issue was tone and it took a dude here in OZ who built two Marshall amps with exactly the same components....except for the coupling caps.....the result was absolutely no difference in tone. I have used basic caps in a lot of my builds, after realising hey these Orange Drop caps don't sound any different....It was pleasing to have it confirmed.
Good to see you again Tony great amps and discussion. Tony fixed my F**kup on a klon pedal build and it now is my favorite green machine.
M Fowler, good to see you here too. Glad that pedal still works! :)
Ha, DIY Layour Creator is my work. What a small world :)
+bancika nice! Thanks for your contribution!
you are welcome. I'm a big fan of your channel. I also build guitars, amps, pedals and love converting vintage gear into guitar gear. When you have a chance, please check out my website, I'd love to hear your feedback. The url is diy-fever.com/
I use those yellow caps from AES Too, I have never had a problem with them except the legs break off really easily. I thought I was the only one who has had that happen.
This Guy's Thinking and Approach to his builds IMHU are on the MONEY. Everything he says is Genuine, I hope this company prospers . great show !
I am listening to you via a PWM amp which has the same as a vacuum tube amp.
Two amp builders talking shop ,great video Brad and Tony, we need more videos like this,but then you'll get your Cork sniffers start to add their two cents. Not to mention your secret sauce, magic caps.Thanks to you and Tony, Peace .
I love ❤️ “Ole” Rusty, that’s just Cool 😎. Rock On Guy’s
Brad, he was testing you on that resistor positioned on the bypass capacitor switch. He was checking you out to see how knowledgeable and experienced you are.
Brad,Thanks for getting back into the guts of an interesting amp(s), as well as for the meeting of the minds; welcome back after your necessary hiatus....gitarrrrists, come out to playaaay (clink, clink)...please do more along these lines...BTW, I have a very nice copy of that Blencowe (he be da bomb!) book that I'd part company with for just $3K...couldn't agree more with your take on metal films, although there are times when I wish I could still find tantalums at a reasonable price...
chokkan7 tempting price. I couldnt in good conscience go a penny over $2995.
Is that a sale, then? ;)
Lemme ask the wife. :D
Your best vid ever! 🎵🎸
Thanks, Ed. I appreciate you watching and commenting, as always, even when we disagree.
Firstly I want your Tee Shirt! loll I remember when that movie came out. I loved amp #3 but I must say #2 would be awesome for some more metal type stuff (IMHO) All were very cool; Your guests knowledge is astounding! I could watch this stuff for hours!! Oh wait I already do, lol Great video thanks!!
Nice Triumph reference
cool find
It was a strange experience.
Amp #3 just sounded killer!
Great video!!! And I loved the shirt!!! "Bra-i-ad, come out to play-i-ay" LOL
The perpetual yard sale sounds like my uncle's house on steroids
Nice little run there 04:14 Most amp builders can barely play a D chord.
That CHARVEL though (opens wallet )
Thanks man. That's really nice of you to say. That Charvel was my first REAL guitar. I'd had others before it, but this was the first really pro grade one. Got it when I turned 16 instead of a car.
Awesome vid, very informative! Where did you get the tuner keys on the tele?
I hate to just not answer you, but I can't. They might be available soon though. I'll keep everyone posted on that.
Ok thanks!
I'd be super interested to know which one you liked the best brad
Ya'll lost me when you said here's the plan but enjoyed the video anyway. All the very best over the silly season to ya'll.
You too Ken. Thanks and Merry Christmas.
This amp sounds really really good reminds me of an early 70s Marshall nice job done on this one i have a question if you can get around to answering is a Fender USA guitar amp even serviceable and are they even worth it ? A solid state USA
What are the pros and cons of using solid state components in the power supply for a tube amplifier? (e.g. transformer, solid state full wave rectifier and filtering )
I've got an identical (probably) Elk missing its tank. Must be a common "problem", hah!
That's cool. I can't imagine there are too many of those floating around anymore.
Thanks for this extremely interesting video, I thought those amps sounded great.By the way, what is so special about these mythical Dumble amps?
Never played one, but I've heard them on records and in demos and they do sound great. But not 30k+ great, IMO.
Your shirt ROCKS! Where did you get it? My favorite movie next to MAD MAX!
The inspiration question at about 24:35...hiwatt is the first thing I thought of
Hey Brad, now that you have had the knobs on your tele tuners for awhile, what is your opinion on the mod ? Im pretty sure I seen you playing a tele in a recent video of yours that uad knobs on the tuners so, Im guessing u dig it.
those amps look like the old sound city amps of the 70s and they are cool.
4:15 ok Paul Gilbert, we get it.. you can shred. lol. Hot fire! Hey I've heard you talk about Charvel guitars before... think you said you owned one back in the late 80s or 90s? Ever see the Charvel surfcaster line? I think they were promoted, believe it or not, by Scott Ian! I had one in the mid 90s, and loved the thing. Serious regret about selling it. Would love to hear your thoughts on that line, or even something about lipstick pickups! Cheers Brad!
Those metal film capacitors were probably mylar going by their yellow color. The least expensive of the film capacitors and obsolete (unless used in the tone section for certain nostalgia sound). Now if they are indeed polystyrene, then leave them alone. Those are considered by many to be the affordable holy grail performing capacitor. Up there and even outperforming some Teflon and PPS (Polyphenol Sulfide) as the best. And yes, there are astounding differences in audio by different capacitors, particularly harmonic artifacts when DC biased. Go polystyrene or PPS if possible. Polystyrene is near as ideal of capacitor except they cannot be in an environment that exceeds 85 centigrade. Since they are not compatible with automated soldering processes, they were quickly replaced with PPS as the higher temp substitute and are becoming more rare. The next substitute is polypropylene and finally PET type capacitors, the (substitute/equivalent) of mylar units. I would love to see a video where you replace the tone capacitors in a guitar with PPS units and run a test.
Old man in a another video that you posted you were talking about a marshall type tone circuit that you're using in a amplifier can you send me a copy of the link for that, much appreciated keep up the good work man.
I have a question, I'm building an amp, what I plan on doing is transferring my Altec Lansing ACS53 multimedia speakers sub and drivers into a cooler to make them portable Its going to be for a license plate guitar I'm building. The guitar is going to be Johnny Lowbowe style I'm having issues how to take the sub box apart. How would you go about breaking it down? Advice desperately needed. Love your videos. Thanks in advance.
May I ask what type of guitar hangers you use. It looks like it would save some space for me to use something like that. I've been thinking about hanging mine on the wall. Thanks
Not sure, Herco maybe.
No wait, it was these: Hamilton by Kaman amzn.to/2rdKFTz
Thanks
I've been meaning to ask, where and how did you come across your tube stash?
A little of everywhere. I buy other people's stashes. Estate sales and craigslist mainly.
I wish every amp manufacturer would put bias points and pots in a reachable area of the amp without having to take it out of the chassis.
i think anyone with knowledge knows leo used what ever he could get for cheap, legend says the 4x10 bassman existed because he got a deal on 10 inch jensens, more legend is that early fenders had clay dot markers because leo pulled up all the clay tile from the factory floor and they punched dot inlays out of it until the pile was gone
Me too! Yea man send me one.
Really nice sounds! FWIW invest a label maker and do not use a black marker.
Mike Conley The Sharpie lettering is just temporary. All of that will be replaced with etched labels.
Yeah, the etching thing is really nice on your builds, Tony. I dig that a lot.
The infamous scene from The Warriors ua-cam.com/video/YeEbtiruH2Q/v-deo.html
I don't know which scene is more iconic, this one or "CAN YOU DIG IIIIIIIIIITTTT?"
Unforgettable ua-cam.com/video/7I9_pZ85zIQ/v-deo.html
Those builds are outright _pretty_ ...
alright dude can i fit one of those jet city loops to a fender greta amp?i have no real idea as its well above my comfort zone but i can follow diagrams etc any advice wood be cool many thanks.
Jon Ault, it depends on the amp model... It can be remote mounted (remove the jacks from the board and wire them to where the PCB must sit)
Volition Amps thankyou for your input very helpful.
What kind of tuning machines do you have on your tele? They’re very interesting!
Jean Larroque It looks like volume knobs that have been fixed to the regular tuning keys.
Brad did a video about this.
