I'm an appliance operator, here to learn ... but I can't help commenting
on the above. What kind of an amp manufacturer says "It'll bang sometimes
when you turn it on; if it happens a lot, replace the $350 tube."?
Apparently the answer to that is Ameritron. Is this a common practice??
My ACOM 1000 manual certainly says no such thing ... nor does the amp
any noises at all.
