Rehabing 42-854 AM/SW Portable
#39

I need a jumbo size bottle of good whiskey!!!!!!!!!!!! This thing driving me nutzzzzzz.
Was working fine late night on the BC band and I don't think sw was working at all.
So this morning I snap it on and it's dead!! GRRRRRR! Audio works but I seems like
the IF is dead again. Did some poking around with the generator and wouldn't pass
any 455 signal. My generator has a flaky attenuator which may have been the problem.
Then the IF seem to be working but wouldn't tune in any stations. Hook the generator
to the ant and fed in a signal 455kc above a local station, pick it up fine. GRRRRR!
No LO. Clean the tuning cap, checked the ground connection at the cap. It work
for a few minutes and died. Recleaned the 1LE3 osc socket again. No joy. Started
poking at the tube socket terminals and poking the control grid pin of the oscillator tube
seemed to get it oscillating again. So now all is well with the BC band but how about
the SW? At first it was dead. Then I took a closer listen and it was working but
would die after a minute or so. That turned out to be a bad oscillator tube works
fine on the BC band but not up in the SWs. Tested abt 85% on the tester. So far
it's been working for a hour on SW. Got my fingers crossed and a shot glass!!
Still have to hook up the loop ant and do the RF alignment.
