[Amps] Alpha 76/78 front panel 'flag' buttons

[Jim Barber]

Does anyone still have an inventory of the 76/78 switches? (no, I 
haven't called Alpha, this thread got my curiosity up)

I have a 76A that could definitely use a new set.

Thanks,
Jim, N7CXI

Pulled the button off and wrapped a single layer of scotch double sided tape around the square shaft end; about 1/8 inch was left to overhang the front end of shaft.  Fold it to cover the front of shaft facing you.
