Hello boys and girls!
As part as a new product line for my PCBs, I've decided to venture into a Trainwreck style PCB! Took me a good couple of months to get everything sorted but here's the final result!
I'm planning to send this out to the manufacturer next week, and it will then available on my website (https://www.aaelectronicspcb.com/)
The same board can be used to build the Express, and the Liverpool!
Let me know what do you thinks and if you have any suggestions

That's very cool indeed , I'd be keen to grab a couple of boards , would it fit in a Fender tweed style chassis ?
that's what came to mind. I like how you can build either amp with the one board
Looks very good, great work! I see you indicated 6V6s and a PT secondary of 260v-0-260v I assume your PCB would also work with EL34s and a PT secondary of 300v-0-300v?

Yes, that's the idea! I try to design most of my boards with modularity and flexibility in mind! In this case you can build both models by only changing a couple of jumpers.
Also, answering your question, the board is 365mm x 62mm in size, so it will fit in a Fender tweed style chassis.

Yes, absolutely. You can use the power section and PT that you wish!
Just fired up the Express Build , Loving this PCB , I squeezed it into a Hammond Aluminium Chassis and it's turned out a treat . Sounds fantastic , I did some slight changes as I didn't want it the same as my Barwatt Express Head , And I had an old JTM45 OT spare so I went with that and used KT66's , Also added a MV (Type 3 from the Trainwreck pages) using a 500kB pot ,
Very happy with the results and the PCB is of such high quality I can't recommend it enough if you want to build a compact combo style Wreck ....
I bought 2 x PCB's I'll build a Liverpool with the next one , But I'm only going to use 2 EL84's instead of 4 , See how that turns out
Thanks Andrea
Now to build the cab , A Marshall 18w style 1 x 12

Looks FANTASTIC! Thanks for the kind words
Would it be possible to have some sounds samples or a video of your build? Would love to add this beautiful build to my testimonials page
Which transformer would you recommend to buy in Europe for building the Trainwreck based on your PCB and schematic with 6V6? Maybe the Hammond 270DAX? I have the PCB here and want to slowly start sourcing parts now. Thank you!
I wonder if you will do another Express PCB that allows the tapped plate resistor like the Komet amps. Then there is the choice between the two 1000pF or 2200pF and the other possible value a 4700pF cap. The amp sounds quite different when the cold clipper is bypassed. The bass response is huge from memory.
