Joe, I'm about to start my first amp build. Where do you solder the wires that have to cross beneath the board? Do you solder them to the underside edge of the turret, or do you strip the wire and insert it up into the bottom of the turret? Thanks.

Great build! cabinet looks awesome nice box joints!

Do you study electrical engineering for this? I am going to uni this year and I want to learn how all these things works, but this is really great

I bought a 5F2A chassis kit from Mojotone (for a gorgeous Ted Weber cabinet). I didn't like the way it sounded. It sounded really off. Finally I modded it to the original schematic, and threw in a Soursound OT and a power supply choke. Speaker is Eminance GA10-SC59, pretty decent. (I know that the original had an 8" speaker. Who cares?) It sounds awesome now. It is a really cool practice amp. I have an attenuator before the speaker because it can get pretty loud. This amp is a winner! Good work.

Slot those hinges so you can remove the lid completely, add some foam to the top & bottom lids for a form fitting no rattle carrying case. Don’t drill holes, use hot glue to secure cables, glue on some rubber feet & add a few bumper stickers

Had no idea this was even an option. I’ve been looking at getting a tweed delux but didn’t want to shell out money for a new one. This is a great option if you have the skills already.

Great job Joe. Looks and sounds fantastic. Thanks for sharing.

Would this map work great as a pedal-platform even with some high gain pedals ?

No offense intended! But And I can understand that you keep the wires long, (to not break the parts with heat) But... this is VERY long, TOO long (I think!) I also think you should think about it carefully, is it smart to make the amplifier in a cabinet with the speaker? (in connection with vibrations and resonances) Healthy and Friendly Greetings from the Netherlands! Rob

hi joe,id like to make aluminium chassis ,can you tell the dimension before bend. thanks a lot

Fantastic video! Really enjoyed watching this!

Just wondering. Who does your nails? You need to fire them that looks gaye af

how much you selling them thangs for?

Did you make your own cabinet plans or re-use existing ones?

Awesome video man!! Turned out beautiful, and I love the clear poly finish with that maroon grill cloth, very clever. Don’t know what your budget was, but if you build another one I would use the Baltic birch cabinet grade plywood. Super high end and clear perfect grain if you wanna have just straight wood finish but even if you wrap it in tweed, tolex, etc. it’s the absolute best sounding wood for a cabinet! Cheers and again great craftsmanship and attention to detail. If you ever decide to build to sell I would be first on the list. Love the sound of that circuit! Lazer Bro.

Great job! It's a labour of love but so satisfying. 🤗

Maybe heat the contact area of the tape just in case it has a coating

Nice job.

The first modification I would make to the 5e3 would be to look at the Dearmond R15 which is very similar.. The volume pots have a slightly lower value. and hence the first coupling caps are also lower value.. I would not change the first coupling caps in the 5e3 but the ones in the power section you could lower to 0.022 which cuts of frequencies below 35Hz (well below the guitars range).. I would increase the first power capacitor to 30microfard. (the higest for a 5y3 rectifier).. I would make sure the voltages are within specs so i could use a 250 to 330 ohm bias resistor on the 6v6s. Trying to cool down an amp with high voltages will require maybe a 510 ohm bias resistor. but I think the amps sounds better when voltages are proper for a 6v6gt tube.. Plate to cathode voltage no higher than 350 in a cathode biasd circuit.

How about do some troubleshooting and testing resistors? Of do you think replacing capacitors are all that is needed to repair a vintage tube powered amplifier?

Yea I always find a glitch in my planning and have to extrapolate a bit, but that's part of the challenge... If it were too easy pedalboard companies would go out of business. Nice job!

Thanks so much for sharing that. I’m good on electronics, but the woodworking and the metalworking…I would never be able to do but it’s great to see someone else do it! Sounds great. Also nice you update below with changes (baffle, tube sockets, etc.). Thanks so much!

Wow nice work!

I also built a 5F2A. Ended up using as you described, as a clean platform with a pedal to push it. In the end it replaced my 5e3. I tweaked the circuit for tighter bass response (+1 22uf 500v cap on the power stage filter), reduced the preamp gain so it stays clean to 60% volume (reduce V1a cathode bypass cap down to 1-4.7uf) and increased the preamp voltage to 285 (swap 22k drop resistor for 10k). Added some protection diodes on to the rectifier (series with the AC) which bolsters the rectification to keep things tight. Only other mod/detail is to use a class 2 ceramic cap on the tone not a film cap or a mica. Lots of extra lovely harmonics. I use that set at 50% volume in to the G12Q. Great cleans for chords with the volume rolled off a hair but thanks to that wonderful speakers capacity to break up if you dig in it goes pure filth. For lead and crunch I use a Catalinbread Formula 55 (build your own the layout is online) which is a JFET based reproduction of the 5e3 preamp. This pedal + the above setup gets you everything from clean tweed to Crazy Horse. The only other pedals in the signal path are a SurfyBear Metal spring reverb and a Belle Epoch Deluxe (Echoplex preamp replica). A Les Paul with some Throbak KZ-115's is God Tier in to this but I often also just use a humble Baja Tele. Best recording and small gig amp you can get for the buck imho. If you haven't already, definitely get yourself a few of those RCA black bottle 6V6's. HUGELY superior to anything in current production.

Great build dude! That G12Q speaker really impressed me. For me it was the icing on the cake of this build. I love how I can get lovely big rich cleans playing normally, but if I dig in, the speaker just EXPLODES. A lot of people hate early speaker breakup but for me its fantastic as it really adds that "melting tweed" vibe at usable volumes.

Very nice job, great sounds, well done to you

shoulda just took the plate to a metal shop and borrowed their press brake

So rad!

Awesome

This is a great project. The only thing I'd add would be some rubber stops on the bottom of the box so the board doesn't slip around. Cool project.

Nothing like buidling a cheap amp and using JJ tubes for the worst sound quality.

That's excellent work, you should be really proud of yourself. Playing through something that you worked hard over, and made yourself must be really satisfying. Just 2 personal preferences on my part, I might have been tempted to make the amp as a separate head and cabinet if you had the wood, make it more modular and can swap out components more easily. And at about 24:25, you pull on your guitar lead a little and risk either damaging the input jack, or pulling the whole amp forward onto its face. This is probably why most amps have their input on the front so that if enough pressure is exerted you just pull the cable right out of the jack. Plus at a glance you can see what the volume, gain etc. is currently at without standing right over the amp. That aside, I'm impressed by your efforts here, well played. 👍

Beautiful!

I wish I could do that

Nice work. And good commentary too. So many people say the same thing 3 or 4 times in a row on these kind of videos but yours is concise and clear.

Excellent job👍

nice Pedal

this is cool! I just ordered a board in a box from Etsy and your idea of including the input + output sockets is something I want to do when I get it!

I wish I had the electrical knowledge because I am a fine woodworker and fabricator. I always see electrical engineers do sloppy wood work and not be as OCD as I would about the circuit boards looking factory made. My Goldsmithing experience would help. Pretty cool.

Hi, I also built one on my own but not the cabinet. So surprised 'cause yours does not hum!! Could you share the grounding method you applied?

Am I the only one that noticed the anal chorus?

Is there no clean sound or does it go straight to overdrive….?

I always heard you shouldn’t turn on a tube amp without a speaker hooked up…?

Or you could spend 10 bucks on an automatic center punch which is much easier than a hammer and a punch 👍🏼👍🏼

Watch them fingers bud!!

If you don't care for alnico there are much better ceramic speakers in my opinion than Jensen

I'm surprised you used that cheap Jensen speaker for your build. It will sound way better with an alnico from Weber or Eminence or anything but an Italian jensen

Great job, young man, very nice workmanship... Only thing I see that I would mention is the output transformer should be at a 90° to the power transformer (so 1/4 turn) to cancel a magnetic field for noise canceling purposes look it up on the channels you listed. It sounds good however and I wouldn't worry much about it, but something tells me you will be doing more of this. Knowledge is power, carry-on! ✌️👍

What a great lookin amp you built. At 4: 11 You have clean wiring. Your 9-pin socket looks like a yellow-legged spider. What is the idea behind having tube socket wires running close to the chassis before reaching to the board ? I see you bumped up C3 C4 to 10uF. What is that pad under the filter caps ? That resistor on the first 16uF 475V - is that for discharging your caps when you power off ?

any time you want to bend aluminum do it on a hard surface or a realy hard pice of maple then screw a pice of angle iron throw the wood in to the bench then use a nother pice of anle iron clamp with C clamos vice grips youll get a better bend but hey man nice work shop
