I have a Princeton that's missing one of the mounting screws. Does anyone know what size they are? I found some at TAD but I'd like to find something closer.

Not sure, they are weird coarse threads meant to thread into a existing hole, but others will work. Take one to the hardware store and match up the shank diameter and the coarsest thread available on a self tapping sheet metal screw or other.

Home Depot (and other hardware stores like Ace) Amazon also. .... have these self tappers with similar threads. They have a drill point on them though. You can cut them, but warning... the drill tip is hardened and you will need an aggressive cutting device. Bolt cutters work.

They're #8. I haven't had a missing board screw, but for missing transformer or cap pan screws, I've used 8-32 swageform screws. They will form new threads and go in nice and snug.

When I compared the 8s I have the threads looked different than the old screws. But good to know they will cut new threads. Never heard of swageform, looks good!

As noted, those are ‘self-tapping‘ screws. Notice the taper to the start of the thread? Probably 8/32. And yeah, different from #8 machine screws that thread into a nut.

Doug carries a nice selection of self-tapping screws, but I think they’re the short kind Fender used for mounting OTs etc. He tells you how to use 'em. Hmmm, what are those vintage part sites that seem to carry everything Fender?

Thanks King Fan!

I also ordered black solid core from Hoffman which I couldn’t find at the other usual places.

Here is the AA1164 I am restoring before and now. The holes were bugging me. Also found a wire under the board in parallel with a cathode resistor & bypass cap.

And the black wire will go for an all black 5E3 build. How I feel inside:
