- Then did he raise on high the Holy Tone of Antioch, saying, "Bless this, O Lord, that with it thou mayst blow thine enemies to tiny bits, in thy mercy." And the people did rejoice and did feast their ears upon the Beatles and Stones and Monkeys and Troggs and Ramones and Eels ... Now did the Lord say, "First thou pluckest the Holy Strings. Then thou must count to three. Three shall be the number of the counting and the number of the counting shall be three. Four shalt thou not count, neither shalt thou count two, excepting that thou then proceedeth to three. For this song is in 3/4 time.
Good old fashioned vintage tube PA amp conversion into a guitar amplifier. This one came out rather nice. The owner added an etched bit of plexiglas to the face with blue LED lights, so it certainly looks the part.

When I was a teen I had a apartment in the ghetto for a couple years. We had 4 rehearsals a week, I remember looking at the stairs for the police and we had most of the block on the stairs and loaded in the first area off the stairs. We had people ranging age 10 thru 70+ I thought they wanted us dead, I killed the music and said sorry, the old guy said you will be if you stop again. Whew! We weren't even good yet, but we gained some serious respect. When the cops did show up they hung out for a whole set before telling us that we had to turn down. They said if you guys turn it back up after we leave, we were here so your neighbors love it. We even had the old guy bring us Delmonico's, his son worked at his butcher shop and he wanted to tip us, awesome guy. We ate good 4 days a week and I worked every other minute painting cars, I was lumping for the truckers unloading truck 1.00 per thousand pound 80,000lbs per truck I averaged 3 trucks and started work changing tires for 18 wheelers and worked up to mechanic and I stopped that job to work at oil refinery called Cibro in the port of Albany NY. I love this country! I always just said I did this before, but I didn't and they knew it because I was too young and I started work. That one job was a 90 hour work week. All for new gear and the wife.
That's a great story MrBrymstond,kudos to you for busting you're ass for the people and the things that you love.cheers man.
Thanks, but I was so excited at the time that I could do whatever I wanted it wasn't work, it was being free and getting the chance to learn. What was work was listening to my wife screaming the whole time I was learning guitar.
Thanks for sharing. It's a good reminder to be good to one another.
Great story. At least you kept playing. I didn't do anything quite as strenuous but being on salary would work crazy hours in a warehouse (BTO's "Blue Collar" was a mental fave) and basically gave up playing as a result. Almost an avalance of mayhem/desire for playing once circumstances changed. Almost down there again. Plenty of Gear but a move is slowly killing my desire to play and slowly, me. I'm 61. Too late to get it back.
Rick Delair+ Do you remember the candle at Cibro burning off methane gas 24/7? I rode their ass to use that gas to power other machines while in the refining stages rather than waste it. Life was so fun having the once in a lifetime chance to pick up another trade it wasn't really work, yet today it's like pulling teeth to get a kid motivated. My father told me at a young age, if you don't learn as many trades as you can, this world will chew you up and spit you out. When I heard that I paid attention.
You should make your own amp, id totally buy one \m/
wow! you really worked some magic on that amp! beautiful feedback 👍👏🏻
Dude you worked wonders with that amp !! It sounded GREAT in the end. Kudos.
I learned more about wiring diagrams on this one video than ever before. Really great presentation and your knowledge is evident. Thanks and keep it up.
Man this is actually a killer little PA! Great job on the input and output versatility.
Looks and sounds great Brad nice mods to it, great sign by the way, Cheers
That sign is a true "sign" of appreciation. Dig it.
Sound test was a highlight... I didn't expect it to sound that good... And the play was ace as well.
Wow, your playing was exceptional at the end. Bravo!
Incredible tone! I'm really liking your posts.
Wow, what an awesome amp. And awesome video Brad!
Thanks, Ed. Appreciate you watching and taking time to comment.
AMP MASTER BRAD: Bring out your dead amps! Bring out your dead amps!

DEAD AMP: I'm not!
AMP MASTER BRAD: He isn't?
CUSTOMER: Well, he will be soon. He's very ill.
DEAD AMP: I'm getting better!
CUSTOMER: No, you're not. You'll be stone dead in a moment.
AMP MASTER BRAD: Oh, I can't take him like that. It's against regulations.
DEAD AMP: I don't want to go to the workbench!

AMP MASTER BRAD: Not at all. See you on Thursday. Or friday.
CUSTOMER: Right. All right.
That's a lot of typing. You're hired. *_:)_*
gonna try to eliminate the blanks for an easier lecture :)
Edit: done, i think its easier to read now ;)
It is. *_:)_*
something like this?
'E's not pinin'! 'E's passed on! This parrot is no more! He has ceased to be! 'E's expired and gone to meet 'is maker! 'E's a stiff! Bereft of life, 'e rests in peace! If you hadn't nailed 'im to the perch 'e'd be pushing up the daisies! 'Is metabolic processes are now 'istory! 'E's off the twig! 'E's kicked the bucket, 'e's shuffled off 'is mortal coil, run down the curtain and joined the bleedin' choir invisible!! THIS IS AN EX-PARROT!!
Replace "parrot" for "amp" and there you have it :)
Fucking lost it at "the Andertons"...
Wow that amp sounds great. Now the nice look it has matches it's sound. Great Job Brad
The feedback is pretty sweet on this one, nicely done Brad!
Chris did a great job on making you a sign, very nice. Mark
Brad looks like he is having way to much fun testing this one out. You ROCK!
Lovely clean job Brad,nice.
Thank you for this video! I have a similar Stromberg Carson PA head that I converted for guitar. It has a nice clean sound but I really wanted to be able to get some dirty sounds from it. I added the master volume like you did and it sounds KILLER now! Cheers!
That sign is beyond amazingly cool.
Great vid. Learned about industrial EL34's and considerably more.
No more 12 min vids X 4 or 5 daily.
Now 60 minute amp optimization videos.
Its Friday here in the UK & Im waiting for my weekly dose of SPF! ;) Cool sign lad. Man you have some cool fans. That's awesome.
Damn, you're going to make me want every old amp out there! The more I watch, the more I understand your circuit changes and choices. I did a RobRobinette mod to my 5E3 clone last week to have a switchable coupling cap. Switches between stock .1 mfd and .0022 mfd. Also built a 5F1 kit with the adjustable negative feedback ala Uncle Doug. Now if only my playing ability will catch up to the amount of gear I have now lol. Hope you had a great 4th Brad!
That sign was really well done and BAD ASS..... might be a great moniker for your channel......
Right on man! Enjoyed it!
Wow!.. awesome tone.... nice job again Brad, you should have a very happy customer upon return.
Great work buddy
I am a great fan of your work
I just jumped to the part where you played through the amp. Because I am tired. It was worth it. Sounds killer Brad and the guy who sent it to you.
Great job Brad! That Dickey Betts feedback man! LOL
I have the same amp. I love your master volume idea.
Among other mods- I added 68uf separate filter node to el84 screens. Made a big difference for noise floor. One of my favorite amps!
Best sounding amp I have heard you demo. Watch out, EBay. I can hear the clickety- clack of keyboards from folks searching for more of those. Only gripe is I would love to have heard an SG or LP through it for a moment as well, but still, solid vid.
Howie Felch It does sound awesome. I still only take my hat off for the masters at Valco who built his Supro though. I love the tone of that thing! Lol
Great sounding amp and great guitar playing at the end!
Lol, thumbs up for your neighbors! Good work, as usualy, Brad!
Bought one of these after watching this video, lots of unhappy components but sounds great and getting better as I fix it up. Thanks for the video :)
Those are some pretty awesome add-ons he did on there that's pretty cool little amplifier makes me want to go out and start searching for one
Damn that was a funny demo. That amp is killer Brad!
Cool, you took a buzzy box and turned it into a little screamer! Nice job.
Nice sounding amp. Well done Brad.
One sweet amp!!Great job!🎸👍✌
Suddenly that old-Eico-40-watter-in-the-barn project moved up on my list.
Hey, that Stromberg Carlson is the same type I redesigned for guitar a couple of years ago! I mentioned it once in a comment I think. For those who are interested (excuse the novel): Totally redesigned the circuit. It's a hybrid of various circuits and ideas. No original caps or resistors at all. Replaced the ever-microphonic 6U8 with a 12AX7 wired as a long tail pair PI (tried cathodyne, wasn't a massive fan), set the first two stages of the first 12AX7 to cascade each other with the Mic 1 volume pot in between the two gain stages. Used a Vox/Fender style tone stack after the gain stages, which meant drilling a hole for the Mids mini pot between the bass (phono) knob and treble (original tone knob). Mic 2 is a pre-PI master volume. Added a Vox cut control, mounted on the rear pannel and pulled the RCA jack out and stuck a toggle in for different cathode bypass caps on the first stage. Drilled a hole for a fuse.
The impedance is switchable, I ran a wire out of the center of the speaker octal socket, similar to how you did. The mic 2 input is now the speaker output.
Amazing tone, my grandfather who has played for many decades claimed it's some of the best sound he's ever heard on electric guitar.
My amp in particular had really high plate voltage, on the upside of 370 volts. Ate through tubes fast. I got that down by installing a small value resistor on the primary of the PT which dropped maybe 5-10 volts. Now the amp is biased to about 100% and only has 307 volts on the plate!
Tone for days!! Nice work!
Man that amp sounds absolutely killer! If I can get anywhere near that kinda tone with my Bogen CHB-50 project amp I'll be a happy camper
Get the preamp right and you'll be rockin' with that.
Hell yeah that sounds awesome man. Hard to believe it sat in a church storage closet for 25 years...Maybe they knew what kind of evil demons were waiting to be unleashed from this thing. Not to make anyone any more jealous but I also have this ones twin at home and I paid 5 bucks for both of them. The lord works in mysterious ways my friends.
Send me the other one and I'll do something different with it.
I'll give you 300 bucks for it and pay for shipping! With a promise to send it to Brad if anything ever happens to it.
Thanks for the offer but I think I’m gonna have to keep it for a while and maybe play a few gigs with it.
Never hurts to ask. What got me is this amp goes beyond sound. The vintage meets technology is cool as heck! Nice job to you and Brad!
Great work.
What a clean cool amp I dig it!
If i didnt know any better, id say you were having fun demoing the amp. Playing with the feedback and distortion.
Badass little amp. Some fine sounding el84's. Killer sustain too. I'm gonna guess about 15 watts and you probably had it pretty much wide open but that thing sounded good. Great job.
What the hell ...the SC SAU 22..great results bravo!!
Wow, that Stromberg-Carlson amp is actually not a bad little guitar amp at all, you're getting some pretty cool clean and overdrive tones from it, I reckon that amp would really scream if you connected-up a booster pedal of some kind, say a TS-9 Tube Screamer, or maybe a Rangemaster Treble Booster, between the guitar and the amp, I'm currently doing some repair work on my Tonebone Hot British Distortion pedal, it's working okay but it needs some replacement pots which I'll get next fortnight, going to try it through my mid 70's Fender Super Twin amp later on, anyway, hope you're having an awesome day, and that you and your family are all doing well, please keep the videos coming....cheers!!!!!!
I have etched plexiglass with bottom lite LED's for my Ham radio "On The Air" sign. They look pretty slick. If you go to my youtube page you'll see it a bit more clear. You'll also hear a half dozen of us messing with or audio. I use a Behringer X18 with my Ham radio gear.
You do great work! Don't let anyone give you crap over tagging off the tabs like you did. It would have been a colossal pain in the ass had you completely re-wired that cap.
Someone was having fun - Great vid
That amp sounds very musical.
Sounds awesome!
you and uncle doug really should combine all that knowledge ,
experience,and flair with valve technology ,between you two
flows a wellspring of ability coupled with the practical skills
necessary to create something unique, that perfect amplifier
circuit we never dreamed could exist, its in there somewhere,!
Great little tone box...!!
Good lord, that amp sounds sweet! It must have been tough to send that one back to your customer!
ha ha people are searching eBay for used ones after this video
Merry Christmas, Brad!, having great friends and customers, like this gentleman, is what it's all about. When you spoke of "lead dress" issues, one of the aspects of avionics, which really came into play in the 1980's, was H.I.R.F. (high-intensity radiated field). You may want to do a little research into the use of ferrite beads, specifically within the power supply, and the inputs. I was shocked to see the difference in 'noise reduction', when ferrites were included at key locations within backplane assemblies, and am certain the the effect may be even greater in amplifiers.
Came in here to say that his plaid PJ pants REALLY gave it a Christmas feeling while opening the boxes.
Top job Brad.Great finale.partner says you have the same guitar face as me!I say,cheekie minx,back to the kitchen!
SWEET!! I don't care what anyone says... tubes sound better.
Nice playing Brad.
Interesting stuff as usual. I thought Stromberg-Carlson was a sort of modern boutique amp, since I have only ever seen modern new ones and they look so contemporary.
Well I have learned something today already.
Sounds amazing.
That's a badass little amp. Channelling a little Jimi, I was afraid you were going to bust out the lighter fluid for a second. Another great vid Yoda ;)
Very cool Slick - nice refurb and great guitar playing. I would have saved the can cap and repacked but I like what you did and naysayers be damned. Getting a good solder on the whole tab to a brand new tab should be pretty easy to do and is not disruptive as you point out. One basic connection to worry about, make it clean, lots of surface area and let it sweat like a plumbing joint.
Love this one! Has the squank of an old hotroded vox i once had & let it go do to the lack of experience and been searching for that tone ever since 🤔 but over the phone I find it very similar. My favorite so far 😍
*Bridge(rectifier) Keeper* _What's your favorite color?_
*Knight Brad* _Stromberg Blue_
*Bridge(rectifier) Keeper* _Correct! What's the average charge-speed of a capacitor in a Holy Tone amplifier?_
*Knight Brad* _You mean the African wax-paper-cap or the American Sprague?_
*Bridge(rectifier) Keeper* _I don't kn_ *oooOOOOAAAAAAAaaaahhhhh .... *
klcbsoft lol.
Got me laughing!!!
Application of the Python ethos to Brad's videos is beyond viral meme worthy.
Must now consider Guitologizing:
"Armaments; Chapter II: Verses Nine through Twenty-One...
(in nasal falsetto) And Saint Brad held..."
Worth exploring.
@@joelspaulding5964 ....in thy mercy...
Brad. I've been following your videos for a couple weeks. You make the electronics and troubleshooting amps more understandable for me. Thanks!
IS there any hope for a misused, abused and non-functioning Crate classic fifty?
I loved the presence and tone of the amp when I bought it but it didn't stand up long to my Acid Rock temperament.
Is it worth the trouble to rework?
I replaced it with a Laney cub, 15 wats of tone but it gets covered up by the rest of the group. I'm missing my Classic 50.
Please let me know your opinion.
Thanks,
Jimi
So awesome this is my best friend sounds amazing and yes he does great work with a laser
i love the feedback at the end.
i wish i could get my amp to do that without having to dime it out.
Dang, That amp is going to be fun
That was FUN!!!
That was FUN!
Love your channel! I have a Vox lil night train and have read that it’s possible to run a 12bu7 in the power section instead of the stock 12au7. Any thoughts of n this mod.
A lot of old PA/hifi tube amps make good guitar amps. The old Italian Geloso amps are a fairly common conversion - and I've also read of a guy who was running an old 1955-vintage Philips 2,000w (yes, that's 2 kilowatts) arena PA amp through a wall of 4x12s...
My first amp was a David Bogen PA. I never did any conversion work on it, but when cranked to 10 it had great tone and decent volume. I was a steady customer for the tube tester at the local drugstore and my dad had to show me how to repair and solder the copper film in the transformer. Like many of us guitarists, in 20/20 hindsight, I wish I kept it. You would be working on it.
That one's really a screamer now... So which pickup gave you the best feedback fx?
Thanx for another great vid. I never get tired of watching you noodle. Awesome!
My grandfather worked at strombergs in Rochester, ny and retired from that plant. In Rochester there are probably many of those old amps laying around.
Turn it up to 3!
When there is a cut to Brad kneeling in feedback prayer to the rock God's I think it's safe to say he likes the amp! Lol 😂😂
Brad have you checked out any of the jet city brand amp? I have a Amelia 50 with a two twelve cabinet. I really like the amp, but was woundering what a amp tech like you would have to say about them.
on those 9 pin preamp sockets, I am unfamiliar with that center tab in the middle. looks like some resisters are connected there. is that tab just a convenient place to junction components? I've only ever used the type that has just a blank home in the center. thanks man. good stuff
fantastic ....that amp sounded killer....even through the twang-caster....lol...nice chops too...
Simply beautiful !! I wonder how well it takes pedals in front?
You're a badass, man.. Hey, I need some consulting on a project, I can do all the soldering
That Theremin trick (feedback) sounded very nice !
Dang - that sounds killler!!!
Great sounding amp,
Btw, I am missing some grid stop resistors in there!
Especially the power tubes to prevent noise and oscillation, but a cathodyne really needs one for blocking distortion.
But, duh, why would you want to block distortion??
Go read into what "blocking distortion" is please. You're mixing something up.
Sounds great
Brad,
Not only are u a great Electronic engineer!?
Also, a fantastic player that obviously revels in the sonic values you impart on these amps.
Do you fix Sovtek mig 50h amps?
Can you describe why you added the master volume? It seems redundant to me but I would love to know the reason. (a volume control on the guitar and already on the amp?)
Sustain from here to Kentucky 💢💥💯👌
very cool, came out sounding nice. Would you ever consider working on any Fender Rivera era amps? I have 2 here in need of love.
I see that Pyramid had a manufacturing plant in Gastonia, NC. My home town, haha. In 1970, my dad fixed up an old Stromberg Carlson PA for me to play guitar through. Had great breakup. That was prior to me saving my money and getting a Blackface Deluxe the next year. Wish I still had the Fender, it'd be worth a pretty penny today...
Great work Brad, bringing out the good tones in that amp. Question ? what kind of knobs do you have on the tele tuners?
I can't talk about it.
Sounds nice.
It's fun to see how tense you were when you began playing ^^
What is the AC wall adapter doing inside the amp?
Pretty interesting Telecaster - filter tron on the neck pickup (+ some interesting tuner knobs). Sure sounded good
Man that thing is sounding good!!! You need to add amp doctor, to your name Brad,lol
Can you please post a revised schematic? I have that same amp, and want to do the same mods. Thank you.
