[Amps] Alpha 87A Problem

[TNeill1648 at aol.com]

I am experiencing my first ever problem with my 87A.  The problems appears to 
be the "ON" switch not functioning properly.

The amp was working fine when I turned it off but failed to turn ON the next 
day.  Fuses are OK and the amp is getting AC power.  The internal fuse by the 
AC strip next to the rear panel is OK also.

Wonder if anyone knows of a method of checking the "ON" switch without 
removing the front panel or if you might know of something else to check.

Thanks for the assistance.
