Possible Oscilator Problem?
#8

May latest progress on the 41-610P was rewiring the oscillator. Many thanks to Chas for the advice on how to go about it. It helped al lot. I took my time and it all seemed to go pretty well. 

I installed it and turned on the set. At first everything seemed as before. The presets worked fine but nothing out of the tuner. Also, the volume was less than before. I probed around to check the connections and also tweaked the BC trimmer a bit. Didn't do anything very significant. At one point I switched from the presets back to the broadcast band and started picking up all local stations, that's progress, but the volume was low and the signal quality wasn't the best. Tried other bands and probed around some more looking for what could have changed. Then I lost the variable tuning reception and, on the presets the voices were sounding  like the chipmunks. I think the oscillator is ok because I was able to tune on stations, at least for a while. 

I'm curious about what caused the volume drop and why the problems seem to come and go. Any ideas on where to start looking?
Thanks,
-E
