what I meant was this:
they call it vvt simulator. as you can see it's a secret :D

I don't think that anyone has the scheme, but I agree that it's the best sounding SS amp I've ever heard.
But it's nothing related to this thread since I'm looking for a project amp.

yeah I know about that but did you know it's also the most complicated guitar amp I've ever seen  ;D I think they use some sort of direct tube replacement circuits. Interesting stuff

Okay, I researched all of these + what I have found extra and concluded 5 finalists *purely* based on the comments of people that own these amps. Sound is the most important thing after all.
However before starting this project I need clarify my vision about his project but my knowledge is simply not enough for that. Here is what I think about the final amp that I should build.

* Schematic shouldn't be much complicated so that I can design a PCB for it (I'm very good at using eda software but unfortunately I don't understand about designing audio pcbs. any resource on that?)

* Over all the project should be cheap. Press the PCB, populate the board and thats it, nothing that will cost too much...

* The most important thing for me: Parts should be obtained easily. For example in my country (Turkey) there is absolutely no way of accessing tubes, tube sockets, output transformers etc... (that's also why I'm not building an AX84 :)) Transistors, ICs and other stuff is O.K.

* The sound of the amp: Although I'm not waiting any thing magical about this it would be great if it had its own trademark sound, something tubey maybe... Also in this project amp the clean channel is more important than the O/D channel because I think obtaining the drive sound with a pedal (tube screamer etc.)

* So far all the mainstream SS amps I've tried sucks at accepting pedals in the signal path. This project amp should get along nice with overdrive and distortion pedals etc...

These are some main lines I came up with. So according to these and schematics that I added here, which one you think I should build. Maybe none of them?

- Fender - Harvard Reverb II (Paul Rivera Design)(&)
- Gallien Krueger - 250 ML(+)
- Lab Series - L5(+)
- Rickenbacker - TR75(&)
- Trace Elliot - Super Tramp(&)

(+) Schematics look scary, not easy to create a PCB I think?
(&) These look pretty simple (especially Rickenbacker TR75) but they all have a reverb tank and as I said earlier it wouldn't be easy to build it in my country. Also I'm thinking using pedals for all kinds of effects - reverb too. So is it possible to remove reverb parts form the schematics. Can someone help me about that?

Thanks very much.

that's a lot of information thanks very much. I researched some of them and they are great for my project  ::)
BTW I don't have knowledge about audio circuits. My projects is just to choose a schematic and prepare a pcb for it. I'm not going to modify anything or build an amp from scratch. But you my friend, have a lot of knowledge on the issue and I really think you should start a community project like ax84 or sorry if that has been talked before...

thanks again  :)

wow thanks, that's exactly what I was looking for :) Any specific unconventional design (topologically) that you liked?

Hello everyone, I'm doing some research about vintage ss guitar amps. Eventually I'm going to pick one and use that as a base to my amp project. However there are many very nice sounding vintage ss amps out there. I need you to add to the this list the vintage ss amps that you had experience or that you heard good things about. Here's what I found so far. I heard nothing but good things about these amps

Trace Elliot Super Tramp
Gallien Kruger 250
Vox Venue
Fender Studio Lead
Fender Harvard Reverb II
Fender Showman
Rickenbacker TR-75

I didn't test it yet, if anyone tries it pls let us know :)

please note that this is not my design
it was sent to 1-2 weeks ago.
he/she was very kind that he/she shared eagle files too
here is a ss and eagle files...

Preamps and Effects / I can't think of a better preamp...

this is the schematic of the famous Sans Amp Gt-2, it's a great great preamp.
Also if you don't want to mess with PCBs and soldering etc. and if you don't have money for the genuine Sans Amp, you can always go with Behringer GDI21, it's very cheap and it's a sans amp gt-2 clone.
