What's in my Dusty Old Vacuum Tube Collection?
Вставка
- Опубліковано 16 чер 2022
- In this video we'll take partial inventory of my vintage electron tube collection. I have several tube caddies full of dusty, old tubes and don't really even know what is in them, other than they should mostly be for guitar amps - 12ax7, 6L6GC, 5881, 6550, 6V6, EL34, EF86, etc. But let's find out!

Brad, what a Great collection of Tubes & The Old Cases, thanks for sharing, i have a Question, What is the difference between a 6L6 G and a 6L6 GC, Thanks, Cousin Figel
6L6G is the old large coke bottle style glass bottle 6L6, which has a lower max plate dissipation than 6L6GC. Considerably lower. Here are the 6L6 tubes in order of date developed and plate dissipation:
6L6 - 19W metal body first developed in 1936
6L6G - 19W Glass Coke bottle ,came along after the metal body
5881 - 23W industrial version of the 6L6G, smaller glass bottle, came along in the 50s, I think.
6L6GC - 30W, the final iteration of the 6L6 family, came along in the 50s, larger than 5881, but more plate dissipation
@@TheGuitologist Thank you Brad,
Loved the stroll down memory lane. My father and I had a little hobby in the early 1960's. Trash collection was on Friday and we went Trash picking after dinner on Thursday. We repaired old table top raidos. He taught me how to figure out the bands on resistors and how to test capacitors. Then a trip to the local grocery store because they all also sold vacuum tubes conveniently in the same case as the tube tester. I can smell the heat off the old tubes now.
I have a bunch of tube caddies you may be interested in. They all say, "Adidastron" on the side.
You may consider making an inventory spreadsheet in Excel / Open Office. I had to do that with all of my transistors and op amps because I kept buying stuff I already had. It would be a great project for the kids to earn some allowance and as a skill building exercise.
Thanks, Brad! This was exactly what I needed today coming home after a long week at the old day job.
Im 57 have never learned about tube amp till this guy Brad,,,,hell i even got the shirts.Everyone else never really tryed to teach you anything but you make it almost simple.I have been playing guitar from 14 to now if you want to learn anything watch this guy!!!
Wow, what a stash..just imagine the value the value of this stuff now, w/the current shortage & rarity of some of these!
You are lucky as hell, I have been wanting a caddy for years, the only time I see them are when they are for sale on fleabay for $3000 with a bunch of tubes no one needs. Probably TV tubes because I mess with radios, reel to reels, record players and guitar amps .I have about 600 to 700 tubes but they are in cardboard boxes and such. I am jealous of your collection. I think part of the problem is I live in New Orleans so after so many hurricanes most of the cool tube stuff has been tossed after getting flooded, especially after Katrina when I lost everything I owned including 10 guitars, multiple tube amps, and lose to 200 old hardcover books. I guess it is what it is. Maybe one day I will come across someone with a tube caddy that doesn't want more than my car costs. cheers!
We had a Tube Tester at the Pharmacy on my corner. They same Woman still works there for the past 60 years. When I asked her about it Her face lit up like a Tube. She laughed and said "OMG, I haven't tested a Tube in so long. I was the go to Person around here for Tubes and knew all the Sales Reps. I sold so many, you cant even imagine." I'm like really? Different times.
Great story... you should interview her and post it on the tube. That is great history there.
Brings back memories of when I was a little shit and watching the T.V. repairman poking around the back of our t.v.Always got it going.I remember when Walgreens used to have a free tube tester.
My dad used to fix ours. He would send one of my older brothers up to the corner drug store to test the tubes, and I'd ride along.
I like the intro graphic with the 80s tape warble.
Thanks! A viewer of the channel named Richard created that. He's a talented fellow.
A nice nostalgic trip, I remember these well. Thanks Brad!
Your collection is about twice as big (and twice as good) as mine, but like me; you seem to have a lot more 6V6's and probably 5U4's than anyone would need.
That is one cool Westinghouse caddy! I love that aqua tweed!
That lizard was just looking for a meal. Got any spiders around mister ,hmm? Love your tube collection Brad.
Just picked up a bunch of old tube from a garage sale. Got some old GE/RCA/Honeywell tubes. Glad you posted this!
YES! FINALLY!. I asked 3-4 years ago to see your tube collection. Love it
This ain’t all of it.
Thx for taking us tubing with ya ... Good tour ...
I have those RCA Wurlitzers in my 1966 Deluxe Reverb. Preamp and Rectifier. Amazing tone.
Create an Excel Spreadsheet with numbered columns containing all of the tubes for a particular caddy and just tape a number on the end of each caddy.
I had already thought of that.
Awesome! Tube tops, tubing down the river, tubes rock! Nice collection.
Those Old Tube Driven Radios
Amps & Stereos & TV's Are Nice If
You Have All Those Old Tubes Around.
Hello my friend I don't think this video is boring at all, I use to have tube works and pro valve power Amp. I really miss it 😪
I Seen One Of Those Tube Caddys
With A Built In Tube Testers on Dennis
The Mennis.
Wow! Impressive collection of tubes and caddies! I only was able to find one caddy ever in my old stomping grounds but it was a cool RCA branded black and red vinyl covered caddy. Did you find any of them full of old tubes or usually just empty??
That Westinghouse is a real gem...Reliatron..classic American marketing hype ...those were the days..
I just bought an old 1965 Ford box truck to turn into my pizza truck and it came with a ton of old radio repair parts and tubes (100's)
Jeez, how did I miss this one! I have around a thousand industrial pulls , 12AX7, AT7, 6BH6s and the like...but most of my glass is heavy RF output stuff...6146, 6883, big CX stuff, 4-1000s...your 807s put a smile on my face though! Do any amps use the 80 rectifier?
Yes. Stuff from 40s and before.
Boy am I late to this one lol. I had to buy a few dozen blank white boxes for tubes without them. A used $25 label maker is good too.
Holy crap that’s a lot of tubes! Haha I have 8 pairs and counting and feel like I have a problem sometimes, but there’s worse things I’ve spent money on
Hot damn, Brad! That's a lot of tubes! Nice collection. 😎
Hey Brad I don't know if you get down towards Paducah very often but last year I went into a store called Anything Goes Trading Company and they had a couple of service tech cases full of old tubes over near where the old radios are set up for sale. I'm not sure if they were all good or not but they had a few hundred tubes in them most were in the original boxes although the boxes were clearly old. Just thought I'd let ya know
Hi Ivy,
Holy buckets. Whether those have good range or not, that is impressive!
Dude i got a stash for you, a full zenith caddy, get in touch!
Cool. Shoot me an email about it and we can talk: bradlinzy at gmail
It's like a load tester when the light bulb bends. You should take it out. You using it would honor it more than it sitting in a rotting trunk. The sands of time only allows some things to survive.
I bet that tester is dangerous. You should open it up and draw the circuit.
Wow…. Legit collection
Wow, I'm new to these tubes but I haven't seen these many. I'm struggling to make my first tube-preamp, down in India. It's very hard and expensive to get them by.
EL37 Is a Expensive Tube by Mullard Only. Used in a mullard circuit by knight KB85 Audiophile Amplifier
If using a 6L6 substitute you have to rebias the Amp
I think the EL37 is closer to an EL34 than a 6L6.
I enjoyed the replay
Thanks for watching, Janice. Good to see you.
Awesome!! Great video 🤘!!
you have some cool old tubes for sure, like to try that last 6L6GC in a smaller single 6L6 amp see how it performs??? hmmm
What happens when you can't get a particular valve anymore, do you need to make something from a bunch of other components?
God I wish I had even a single caddy. My tubes are all over in drawers. My RCA blackplates deserve better.
p.s. Miss the shitpost vids.
Russia called....they want their tube surplus back...nahh nahh
I absolutely dig your collection..
Hi Brad, I’ve got an 18 watt marshal with a jcm800 preamp from mojotone, I have a set of new NOS 12 bz7 tubes and read they were a replacement option for 12ax7 , but I also read that the heater voltage was higher, would I need to make a mod to run these in the amp? By the way I’ve been enjoying your other repair videos, never hurts to learn new skills.
The 12bz7 is a 12V tube just like the 12ax7. Where it is different is that it has a heater/cathode design, meaning the heater doubles as the cathode. They usually did this back in the day in applications where they wanted the equipment to warm up to operating temperature faster. The amplification factor on the 12bz7 is 100 on both triodes, just like the 12ax7. The pinout is compatible as a drop-in replacement for the 12ax7...BUT only when the amplification stage is not cathode biased or bypassed by a capacitor. So the stage has to be designed as a grid biased stage, NOT cathode biased, like in many guitar amps. This will require some rewiring possibly, but they are usable. A smart guy would redesign one of the new kits to be grid leak biased on at least V1 and maybe V2 to take advantage of these cheap NOS American tubes on the market no one is using.
12bz7 can make a nice (and economical) phase inverter if you have the voltage to spare, not as good imo in v1 or v2 as the ax7. A quality 12at7 can be magical in the PI position in most Marshall type circuits, everyone should try at least once👍
Shitpost Friday!

Shitpost Friday!
Man I really miss the shitpost videos.
@@nobodynoone2500 Yes, me too. I seem to have discovered SPF just a few weeks before they stopped and I never understood why they did.
Is there any companies that still make tubes today, or never stopped making tubes? You were talking about modern counterparts for a second, but im curious to know more about them. Are they not as good or? Can you get a modern replacement for any type of tube? Or is there some tubes that they dont make at all anymore and you HAVE to get a hold of an old one?
I’m 72 and quit repairing tube stuff due to arthritis. Got a thousand or more tubes, tons of repair equipment and a few old amps. I want to give it to anyone who will use it. I live in Oregon so shipping would be expensive plus my parts stock
Hey Duane. Email me your details and I'll pass them on to a fellow I know up in your neck of the woods. He has an electronics UA-cam channel too and I'm sure he'd be thrilled to check that stuff out. bradlinzy at gmail
Dam, Sick Collection. i only own 100 total
My tube collection is no where near that organized . When buying tubes, I try to stay away from TV tubes . Is there a list of desirable audio tubes ? I have noticed when buying tubes, people tend to think every tube is worth gold . A list would help when purchasing tubes
The earliest scientists weren't using proper protection as H.A.A.R.P. was being developed and they all contracted H.A.A.R.P.I.E.S.
Milk duds for the creamy chocolate tone...lol.
It's gold mine, or a tube hoarder..you decide..lol.
I am so jealous I just started collecting tubes I know I am weird I have one of those old pharmacy tube testers anyways I don’t know why I find tubes so fascinating. I have a hard time finding older ones where I live in Canada. But am always looking in old amps and organs
The 50L6 is a pentode tube. Rectifier tubes should end in 3 or 4.
Very cool!
Very envious ;-) .
I own two RCA tube caddies that i found loaded with working tubes, some even NOS. There were a lot of tubes in one that were good for a lot of guitar amps. I still have some RCA 6L6's i found in one that remain in my modded Hot Rod Deluxe.
That is a WEALTH of tubes,
Man I love this channel. Is Brad still doing amp repair? I just got a '75 silverface quad reverb, all original, might make a cool video.
I’d love to have that quad reverb to go with my super six
@@mohamedtlass3842 they're beastly in all the good ways aren't they? Lol.
Be sure to keep your window repair guy on speed dial. Also might be good to take some pies or something to your neighbors before you crank it up.
@@user-kc4hd6qu5g I’m doing it because I despise my neighbors
So is this purely for the sake of collecting or do you use these tubes for repairs or sell them?
Would you sell a set of tubes for a Uinvox U45 amp ?
I don't mind watching you fix household appliances, but what happened to the amp repair videos
Brad, I picked up a sizable amount of tubes recently, mostly RCA and (US made) Tung Sol, some GE, Sylvania, jan, Philco, de Forrest, Lafayette, Cunningham and few others.
There is one in there that is about 8 inches long by roughly 1 1/2" diameter with 2 chambers but the base and pins were broken off long ago. 2 lead wires coming out. It has liquid Mercury in it that moves between the two chambers via a hole in a plate inside it. What do you think this is? Tube? Old light bulb?
Might be one of those old high power rectifiers.
LIQUID mercury? No idea. Maybe a pic would help. No experience with anything containing liquid mercury.
@@TheGuitologist New to me too. There's alot of old tubes in here. An RCA Radiotron UX199 that has a tube test sticker from "The Pep Boys". The test date is hard to read but I think it says 1932. I'll email you a pic of that other one. It definitely looks like quicksilver.
Yah I Wouldnt Be Removing Anything
Off That Tube Caddy. Cause It Might Come In Handy One Day For Testing Tubes One Of
These DaysIt Might Be Worth Some Money.
Nice
Got tubes
Hey Brad ... Think I sent you a message on Facebook: My killer garage sale finds today!
Hey, I've been looking for one of those caddies. You wouldn't want to sell an empty one would you?
Empty one? What’s that?
I sold my two big RCA ones a few years ago at a swap meet. Now all my tubes are in a shelving unit approximately 11” deep, 7’ wide and 3’ high. All arranged in order starting with 0.
This is pornographic.
I started watching this video, but didn't see any lawn mowers or weed Wackers, so I lost interest.🤣
Remember A440hz is a world wide military mind control grid. Otherwise known as Beatle Boomer Syndrome. Aha
Isnt this video an inventory? Aha
If Brad manufactured his own tubes, they’d be called “Boob Tubes.” Hey laugh at good marketing ideas all you want🤷🏻♂️
If they're more than a year old, just toss them out.
Too much dust on them.
Love your tube amp videos, not a fan of your political stuff
