When I look at fender type builds I wonder why people keep using those flimsy cardboard eyelet stuff. And to make matters worse they are always mount with 2, max 3 skinny bolts. That board can move all over the place. Bending like crazy. Nearly all of the trouble I've seen on those kind of amps are loose solder joint related. I wonder why
The thick turretboards with multiple solid bolt mountings seem more reliable to me , from a mechanical engineer's POV.
I think the ability of parts to move, even just a little bit is asking for long term problems. Combine that with NO mechanical connections of the wiring and you're creating possible widowmakers without even knowing it.
