I don't know whether it was James Brown, Hartley Peavey, or Mickey Mouse who designed this amp, but whoever it was, they were at once both a sorcerer and a sorcerer's apprentice. If you leave the box shut and never look inside, you'll swear this is some boutique marvel with secret sauce sprinkled all over it, with a circuit board probably caked in epoxy goo to thwart the would-be cloners, à la Howie Dumble. But no, this was a run of the mill production amp for its time, made as cheaply as possible in a USA factory at a time when production of all things guitar and electronics related either had moved or were moving overseas to Asia. You might even call it one of the last great American amp designs, which also happens to be a simultaneous piece of unmitigated donkey sh-t. This is a heady mix which is advisably drank in measured doses in a studio or other climate controlled environment and not relied upon in any way at a gig, and you'll soon see why. So sit back and enjoy as we repair and demo an early 1990s Peavey Classic 30 guitar amplifier - the WORST 'good' amp I've ever repaired.

What a great video !! It reminded me of the nightmare of coping with a Vox Cambridge (?) amp several years ago, which required about 9 hours of disassembly just to reach the circuit. Then your PCB circuit tracing at the midpoint of the video reminded me why I shun this style of construction like a leper who wants to hug. The trio you have assembled for the audio demos was splendid.....Ollie & Jack need to take some notes.....climaxing another fine video from my favorite amp guy. Thanks !!!

Thanks Doug. Good to see you, my friend. It's just a real shame they felt they couldn't sell a true hand wired version of this same amp without all the parts deletions and weird design choices, like IC reverb. Some things they got right, like the 12V per tube (36V total) DC supply for the preamp tubes. I think that's a stroke of genius that lowers hum considerably I'd imagine. But then they doom the design with all the other choices. Shame. This could have been an all-time classic amp if not for the cheapness.

Those RC4558 ICs have the same pinout as some other Dual Op Amp ICs such as the JRC4558D, TLO72CP, LF353, all three of those ICs can be used as drop-in substitutes.
@Intrinsic.Recording
@Intrinsic.Recording 8 месяцев назад
Yes, the 4558 is an upgrade for certain. It's a chip that doesn't get taken seriously often, and was used all over mackie consoles etc. Pedals, budget converters etc. I can say I've put them in fader buffer stages of old British mixers a few times, and man does it open them up. Makes them sound way more open and transparent. Cheap chip to. Also the 2068d is maybe even better. Super hi end guys tend to look down on them, and like stuff like THAT and LME49740 etc., but the jrc stuff is great sounding stuff.
@simonkormendy849
@simonkormendy849 8 месяцев назад
​@@Intrinsic.Recording The TLO72CP has the same pinouts as the RC4558 and JRC4558D, except that the TLO72CP uses two JFETS for the inputs on Pin 2, Pin 3, Pin 5 and Pin 6, instead of Bipolar Transistors, the benefit of that is a lower noise-floor than the RC4558 or JRC4558D, as well as much higher input impedances (about 10M for the TLO72CP).

😂 James Brown of 5150/amp tweaker/ Iconic amp designed the classic 30 to be able to get a tube Amp that sound good for under $300 and that was the goal for this amp. The classic 30 has the same folded up boards as the 5150 peavey as he designed the amp for Eddie Van Halen to be affordable, which I guess it was achieved.

Great video Brad. Just back from a gig. This was a cool Sunday treat. Really enjoyed it. The way they have those boards reminds me of a Fender Bassbreaker I opened up recently. Except they built the chassis around the boards. When you take chassis out the case it looks like a square metal tube. Take care Brad.
@lorenzo6mm
@lorenzo6mm 8 месяцев назад
The "Beauty" of the Classic Thirty is the mass production CB design. The simplicity relates to cost of production. It's laughable and Genius at the same time. Somebody has hand wired this circuit on you tube. But they went over the top in mods with the original design. I believe if somebody went to the effort to actually create a hand wired simple chassis and build of this absolutely killer ( FOUR) EL 84 Peavey amp. It would be the Ultimate amp kit build for anybody to have. The tones of the Classic Thirty are legendary. It blows away A Vox AC 30. For a fraction of the cost. IMHO. For that matter a lot of really expensive Boutique amps for thousands of dollars. Hartley Peavey is American legend. The longest American ( SINGLE CEO) owned and operated amplifier in US HISTORY.

I am a tech at Clawsons music they sold these about 26 years ago I have worked on just a few I think the reason the ic capacitors hold up better is because the tubes are el84 the voltages are lower maybe 325 but on fender blues deluxe and pro jr they are notorious for leaking causing an audible ripple the fender amps they are lined up like 47 22 22 22 at 450 500 volts they all go bad I like jj electronics and f&t and a new one from tube depot MOD capacitors.

@kenzuercher7497 8 месяцев назад
I've seen a number of these after they've aged a bit. My memory is what you encountered. The first time getting it apart is a pain. Peavey like Fender seem to run the EL-84s too hot and it causes issues with the board. Like a Fender Blues Junior. Also the filaments might be in series.The Classic also has them running DC for hum reduction, but that might be the Classic 50 Which also sounds great! And the filaments are fused...A "low budget " amp where the value of the amp is maybe less than the repair cost. I fix them anyway. Good job chasing down the odd screen resistor configuration. When these were designed, EL-84s must have been cheap enough to not worry about short tube life.

Its that they designed something that they KNOW will need repair at some time, in a way that made it hard to repair. I would rather have a amp/ car that needs repair more often, but has access to the board/engine in a way that you can actually pull things off to repair them. Its. So. Stupid.

The reason I've heard for eliminating the screen resistors for two output tubes is to make the amp run hotter. It is a vast improvement to do as You have done. Yes the amp runs hotter, but only in temperature, to the detriment of tube life. Without the screen resistor the amp sounds sloppy and "red plating" without any benefit.... YUCK !!!!. You are correct to do this mod ! The increased resistance of screen grid resistors will make the amp run cooler, same voltage applied, and much less current so they will run cooler.

Got two of these in the basement now needing help - one newer tolex style that likely just needs a socket re-flowed but I've been dreading dealing with the ridiculous pcb taco to the point I just move on to the next project. The second is an older tweed one that's in pieces - that'll likely end up getting re-wired into something else. This video gave me some ideas though, and maybe the courage to get it over with. Thanks!

Hi Brad. Have you ever tried to deep-freeze that glue with some ice spray and instantantly give it a small push with a screwdriver or so? I used to do so when I worked in our repair shop and mostly this worked very well... 😊 Beside this, great video as usual. Greets from Germany Chris

I had to deal with Peavey products throughout the late 80's and 90's ... apart from the Black Widow speaker , most of their products especially amplifiers were designed by pond life high on Balkan Vodka and Absinthe.

Good job mate! Did ya replace those microphonic tubes? Crazy how an op-amp chip can blow up so often; maybe from back emf from the reverb? Possibly back-to-back 1N914/1N4148 diodes between ground & the reverb i/p pin on the op-amp may help, depending on the voltage on that pin. Diodes won't switch on till there's 0.6V across them. Hey, you're a one man band then huh? Fricken awesome Mr. Music you can do it all can't ya! Music demo was spot-on & thanks for the video! 😃👍!

I have a 2006 model. I changed the reverb tank from the 4EB2C1B to a 4EB3C1B tank and it made all the difference in the world; more of the classic Fender-ish reverb. The other stinker about these amps is that there is no standby switch. I see the newer models now include that. Finally, on mine plugging in to the external speaker jack does not disable the internal speaker; both speakers are active.

I have a tweed Classic 30 that I purchased somewhere around 1999 and it was a rather extravagant purchase for me at the time. I didn't need that amp. I'm a living room guitar player (not good at it either) and I wasn't too thrilled about that amp. I had the opportunity to use that Classic 30 at proper volumes and it was the sweetest sound to my ears. The clean channel, cranked up to (almost) max volume sounds so, so good but the volume will rip your face off. Not a good living room amp.

I've had a US-build Classic 30 for 19 years or so, it's been all things considered a solid amp. It's my go-to especially for recording Wurlitzer electric piano, it really brings the bark out of the Wurly beautifully, internal build wonkiness notwithstanding. ;) Hard to complain about the rock'n'roll guitar tones it can provide...not looking forward to having to work on it though! (mostly work on Hammond/Leslie equipment.)

The odd screen resistor arrangement *could* make each half of the paralleled tube pairs break up at different drive levels so giving you a greater amount of that overdrive sound or give *some* overdrive at moderate volume levels.
@TheGuitologist
@TheGuitologist 8 месяцев назад
I had considered that too, that they might be going for some kind of asymmetrical output thing also, but I don't think the tradeoff of tube life due to no screen protection is worth it. if they wanted something like that, they should have at least done something like a 470R for the entire screen supply, then give each tube a different screen value above that.

My late younger brother had an early 90s Classic 30. I always hated that amp. In fact when he passed, I ended up with all his music gear. And to me his guitars are precious just for the memory of him. But the Classic 30 amp? It was the only thing of his I didn't keep. I just gave it to some poor guy.

Remember working on my Classic 30 and it was a PITA to work on... always had a few gremlins. You gotta get hold of a Crate Palomino (USA - like a V32) the amp is similar but great sounding. Designed by Obeid Kahn (Ampeg, Magnatone, etc). Would be interesting to get you take on the amp. They did suffer from heat issues due to the design of tube location.

I modded a classic 30 about 15 years ago. As I recall the pot on the reverb was supposed to be a 10k(?) but only measured 7.5k. There were lots of posts on forums about the anemic reverb. The pots are not standard types and couldn’t be replaced. I put a resistor (2.2k ?) in series with the pot and the reverb became a swamp 😁. The original pots were bleeding to much signal to ground. I called Peavy about it and they said, “Good enough for Peavy specs.”🤦‍♂️

Another great video brother! I wanted to mention, over the years I've had a number of Peavey amplifiers, and invariably they all have had solder issues, especially their XR600 PA mixers. Not sure why, but many of the solder points will, what I call "volcano", where there's a cracked ring around the component wire. A few minutes with an iron and it's a fix. I will concur that some of the boards are a mf'er to get to, but in general, the Peavey stuff is pretty rugged. Anyways...thanks for the vids...keep 'em coming!

The clean channel works good. But the effects channel isnt working. At all. The digital display is good though. Do you think it would be worth the money to fix it ?? I bought it used and its in storage. Or i could give you more details. Just going off memory. Thanks 👍✌️✌️🎸🎸

I used the C30 for many years, after using the C50 410 combo, and then the C50 Head with two 1/12 cabs. The C50’s never failed, but my C30 failed four times, due to heat issues. The three circuit boards at right angles are connected by tiny wires that were breaking due to heat. Finally unloaded the amp, for a Supro.

My first guitar amp, back in 1998. Decent tone, for the price. Could not live with the reliability. That circuit runs the output tubes extremely hot, especially if you don’t watch your bias settings. Dealbreaker was those flexible jumpers between the multiple PCBs. Just on borrowed time until they eventually fail.
