Have a friend with an AL1200 that recently stopped transmitting on 80
meters
only. Works fine, full output on all other bands.
He said he heard a hiss and then it stopped working on 80. I looked
at the
bandswitch contacts and loading coil and can see no evidence of
burned/arcing.
We tried to load it again yesterday and a nice burned odor permeated
the
room. No output again on 80 only.
Any suggestions? I am leaning towards the input circuitry but he is
dreading
shipping it back to Ameritron.
Any suggestions as to reputable amp service work in the midwest in the
vicinity of Louisville, KY? He would much rather drive a little and
deliver the
amp rather than risk shipping this beast.
Thanks for any help/advice and will pass it along as received.

My AL1200 stopped working on 80 because the solder joint at the tap on
the main tank coil broke loose. Give the wire a tug and see if it is
still connected. It may have broken loose but only pulled away a tiny
bit so as to not be readily apparent.
Possible, but a burned smell could be a problem with an 80m padder C.
