Subject: [Amps] AL-80A - Pi/Pi-L Switch Wafer Failure due to arcing
I have an Ameritron AL-80A, which unfortunately during the KH1/KH7Z expedition
experienced bandswitch arcing when used on 17m in the 20m bandswitch position.
(Oops!)
The arc melted the contact on the Pi/Pi-L switch wafer. The contact at the 40m
position is just gone, and the wiper has a bit of a corner melted off.
I have experience in replacing switch contacts, so that’s no problem, but I’m a
little worried about the condition of the wiper. How hard is it to obtain a
replacement switch wafer?
Amp is still running. I soldered a bit of hook-up wire so that it is
permanently in the Pi position — so I can’t run it on 160 or 80m. But I would
like to fix it.
Any ideas?
