Philco model 048 set tester
#1

I am at a standstill. Got some battery packs and a new #30 tube. Few resistors had to be replaced. and restufed the capacitors.Problem with the frequency generator. I get excellent readings on my frequency counter.That's if a pull the top corner of the variable condensor towards the front of the instrument. Let it go and I loosethe signal.I cleaned the variable and resolderd all the joints and still the same problem. Any one had any experiance with a similar tunning problem.
I also replace the attenuator control .This was a 500ohm wirewound pot. I subbed with a AB 500ohm pot.Would this bother the attenuation . Not sure if the original is linear or audio I really not sure of the difference.
Thnks..
