Philco 89 (123) (Update-Coil rewind)
#12

Thanks BIll,
I installed a couple of 4 watt parts , and not I can get the set to receive. The resistors didn't get hot.

Today, I am going to recheck the remaining dogbones, they all have been way off in this and other sets.
The symptom is, the set will receive from 1600 and tune down to about 1200, then tuning a little more will stop receiving.
I doubt it's the tuning cap plates, but I will still check. It does not stop abruptly, but 'fades' at a certain point. I suspect there is a low pf cap that may be leaky. The SW band does the same thing, receive on the high end, then fades off.

The issue about moisture in the osc coil, I wonder if this would be a symptom? I'll probably remove that also and have a look.

Well, that''s the plan for today, at least the set is somewhat working.
Will let you know what happens.
Gary.
