Here’s another great example of a PCB based tube amp that shouldn’t be … for starters the head of one of the screws that holds the PCB down overlaps against the “Screen” voltage rail … a little too much torque on the screw and guess what ?!
another thing, the PSU grounding is done through the potentiometer housings – one of the strangest thing I’ve ever seen in a tube amp !! … it baffles me that a corporation trusted some “designer” to do that
last thing, the profile shot above shows how pressure from the tube retainer has pushed the board out of shape in time – total silliness
