Get the switch from Ameritron...it is a PnP replacement.
Then quit underloading the amp; that is the major cause of zapped
switches. Load it up to maximum obtainable output with 100W of drive.
Then back the drive ONLY down until you have ~ 800W. Do not reduce power
with the amp controls.
There is something amiss in the basic design...same as the AL-80... that
causes zapped switches when underloaded.
