It's a complete recreation of a Marshal 2204 made by one of the guys on AX84.com. The custom designed PCB board is 1/8" thick with 4 oz. copper traces and gold plated through holes. Every preamp stage has a separate power supply filter. Even if you don't like the red & black color motif, you've gotta give the builder credit for immaculate attention to detail.

Too bad Marshal doesn't make 'em like that, eh?

Cheers,

Re: PCB Can Be Done Right!

Are you as bugged as I am by the strip of electrical tape marring that otherwise immaculate layout and wiring job?
 
Re: PCB Can Be Done Right!

That is gorgeous!

Any clips of this beast? Do the individual preamp filters improve the sound noticeably?
 
Re: PCB Can Be Done Right!

There's two types that would do that. Artisans that want everyone to recognize the perfection....or crystal meth addicts! haha
 
Re: PCB Can Be Done Right!

nothing wrong with pcbs if they are good quality. Mesa boogies are all pcb....you may or may not be a fan of the various sounds the amps in the range make, but there is no denying the top quality craftsmanship and attention to detail.
BTW that amp in the pic is incredible....

Boogies are notorious for their bad layouts, but the actual craftmaship is top notch.


This pcb amp is done very well, though I would have gone with pcb mount sockets as they make the servicing and modding of the amp much easier.

I also love the attention to detail! You see that every bit of wire is laid in with thought. That's handwiring in its best.

Finally someone who knows how to do heaters properly (not looping the Pin 9 connection around the tube and going over the tube). Inspiring work for sure. He should be proud. I should post there more often. But I see a lot of parallel wires... Sometimes that clean looking right angle layout isn't the best for noise reduction, but I'm sure this guy had that all figured out ahead of time.

Christian I'm going to build a PCB 5E3 and send it your way rofl

can you edit the photo with a circle or an arrow or something to point out what you are referring to ... sounds interesting and important, but i dont understand it - dont know what i am looking for ... a contrasting pic of a crappy job (looping/going over?) would help to ... and what is the effect of doing it 'right' as opposed to doing it 'wrong'? is it a tone quality thing? a reliability thing? a serviceability thing? or just an aesthetic/presentation thing? something else?

thanks

Re: PCB Can Be Done Right!

Wow... that's beautiful!

An amp like that needs to sit in an all-plexiglass box so it can be seen and appreciated all the time. When I win the lotto, I'm gonna have him build me one in a see-thru head! :D
 
Re: PCB Can Be Done Right!

That certainly is pretty!

The only major issue I see is that it's gonna take quite a bit of disassembly when those filter caps need changed.

And for the record...I'm not a fan of individual filtering of stages...it's a mojo killer in my experience. Cross-talk between stages through the power supply is one of the reasons why certain tube amps "breathe"...and early Marshalls are one of them. This amp wouldn't have that. Now don't get me wrong, I'm not knocking this guy and I do give him an A+ for effort and execution but when I think of a Marshall, I like a little inpredictability.
