Does anyone know a good place to pick up some silver push buttons? Partsexpress has pretty much all plastic.

Radio Daze has metal push button switches:

* Dielectric Strength 1000VRMS Min. * Contact Material: Copper Alloy/Silver Plate
* Contact Mechanism: Slow-Make, Slow-Break Butt Contact * Screw Terminals
* 0.50" Mounting Hole * See Figure A For Dimensions
Part Number Type Action
( ) indicates momentary Actuator Price
Each
S-PB-SPS1 SPST ON - OFF Metal $4.99
S-PB-SPS2 SPST OFF - (ON) Metal $4.99
S-PB-SPS3 SPST (OFF) - ON Metal $4.99
S-PB-SPD1 SPDT ON - ON Metal $5.49

These are on the top of page 29 in the current (#306) catalog.

I can't speak too highly of this company when it comes to vintage/restoration parts. AES has been steadily moving toward supporting the guitar amp business, while Radio Daze remains committed to the entire spectrum of vintage electronics.

You can download the entire catalog as a pdf.

Great reading!

You mean you can't speak highly enough? You're saying they're good, right? I just ordered a 5/8" chassis punch for making holes for 7-pin tube sockets. Can't wait for it to arrive!
