Re: SMT and tube amps

I think most of the issues mentioned are with design, not surface mount technology as a whole. (aside from the lack of markings on caps which is a massive pain when troubleshooting, though arguably this is a design problem with the PCB silkscreen.). SMD vs through hole is another pcb vs eyelet boar...

When talkin about pedals you usually have a DC supply which comes already filtered (best case, there are bad DC supplies...). In tube pedals you usually have a normal low voltage DC supply which ge...

Coming to the question: I'm seeing more and more tub...
