I plan on fixing stuff till I can’t , I really enjoy it.
If or when my soldering skills go to crud, that will be when it’s time to call it quits.
I’ve seen a lot over the years. ?

Lou, If only to be a fly on the wall!
Amp Guy, You mentioned soldering. I remember B4 I retired working in
the automotive field, watching pretty good mechanics soldering, was,
well, lets just say funny!
Guys could rebuild a transmission with their eyes closed but you
better keep the soldering irons hidden!!!

John, that was an amplifier that belonged to me. I was sent an
AL1200by a person up north of here to look at, he claim the amp was
was problematic. I told him how to pack the tube for safe trip
about 300 miles. I got the AL1200 safely. I put the tube in the
amp and the tube was totally dead! Wouldn’t do anything. I
called the guy and told him the tube is totally dead and I
couldn’t get a lick of power out of it. He said it was working.
Anyhow I said you need a new tube. Trying to get a new one was out
of the question. Finding a good used one is sketchy and I
wouldn’t stick my neck out. Bad situation at this point. Told
him I would take the 1200 and give him this AL1500 of mine which was
working just fine. Did a swap on the RF deck and he just paid less
money than he’d pay for a 3cx1200a7. Shipped him the AL1500. He
got it and in a while mentioned issues much like he had with the
AL1200. I told him with two amps acting strangely it sounded like
antenna or feedline issues. Sounded like high common mode to me.
Told him two amps not working properly is suspect of load or
something. Again amp working fine at time of swap. Ends up he
sells amp to a guy. That guy blows up radios. Amp guy gets it and
finds it’s got a bad tube. Probably arcing plate to cathode
sending power back to radio. So who knows what happened in the
interim? Amp eventually got another tube. A bad tube problem the
cause of guy #2 problem, probably blown like the original 3cx1200 in
the amp of guy #1. Other issues like a line filter were already
installed when I got that amp. A harmless line filter doesn’t
blow radios but was removed. Step start relays always have a black
spot over time but still work, doesn’t blow radios. The so
called train wreck amp worked for me no problem. It seems to me
the that amp fell victim to the same fate as the AL1200 with a bad
tube.

Could you elaborate on what "installing the proper way" is?
Without
those details, this statement is not very useful.
