Amps with PCBs can GTFOML, Especially the ones with double sided PCB tracks.
When faced with quality, I recognise it every time.

Bet you AI won't be able to repair these. Although it might help diagnose the fault. To the landfill with them I say :wink:

It doesn’t help that they often use lead-free solder on those, so you have to roast the board to remove components.

AI will analyse the circuit and figure out a way better way to produce it and then a robot and production line will make a better one, all within milliseconds.

Working on a nice and clean FX loop that can be spliced into amp circuits:

It'll be tested in a 22w JCM800 clone and see how we go. It 'should work' but we all know what that means.

My pal is nearing completion of a mini jcm800. 20w ish. But look at those transformers. And look at that wiring. Puts many boutique guys to shame.

It looks great, those heater wires are so tightly twisted that the electrons will have to turn sideways to squeeze through! Did your pal design it and make the chassis and turret boards? And what is the IC socket for? (asking for a friend) :)

Yes, yes, and yes. He even made the fibreglass.

The IC socket is for the FX loop design I posted above, but the PCBs took too long to get here so he made the other smaller board for the loop.
