I was told, years ago, after experiencing the same malady in a Yeasu 2100 by a more experienced ham (sic) to never change bands with the amplifier on.? Seemed sorta silly? to me.? I heard later on in my journeys’ down ham’s road, that was only true when changing the band switch to 160.

I’ve never had a band switch problem, but let me tell you about the T/R relays in an AL-82…….I actually have 4 in my cupboard, just in case.? I have been through 5 already on a 3 year old amplifier.? L? I can even do it now without getting shocked!? J

I had one of the first AL-80s quite a while ago.? It was very good at vaporizing one of the bandswitch contacts when operating on 160.??
