I was a little lazy with the arrows, but that should give you an idea.

Thanks,

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.

That's how they work until they're received, then they switch boxes.

Just another suggestion……never use a transformer bolt for a ground connection. Thermal expansion WILL CERTAINLY cause them to loosen over time. Always make ground connections to the actual chassis using a through bolt connection that utilizes a locking nut AND some sort of anti vibration solution like blue lock tight. The grounding circuit is the most important circuit in an electrical devise. It’s definitely the one thing you want to get right. 👍
