Nathan's Philco 118MX
#21

Thanks Bob!  Icon_wave

I won't post much on the electronic restoration - so I'll just add it here to this thread.

6.5K Resistor

Part #60 - the large wire-wound resistor - tested open.

After replacing it with the one from a parts chassis and putting in new electrolytics I tried bringing it up on a variac. No sound...

Speaker

Even though the speaker looked to be in really clean condition the output transformer tested open.

Fortunately I have a spare H-13 speaker. And it lives! Actually it works pretty well but I'll still go through and restuff all the caps.  Icon_thumbup

Tuning Condenser

After making sure it was mostly working I got to the root of the original problem - the one that resulted in an extra hole. I swapped in the tuning assembly from a parts chassis. It was also the perfect time to put in new tuner rubber mounting grommets.

Before:

Note the addition of a shaft parallel to the tuning condenser axis. The original mechanism uses a pulley system to give much finer control.

After:

(Tone control is out.)

Shadow Meter

The shadow meter tests good, although it doesn't move much. I verified that it moves correctly using a 9V battery. It will likely do much better after I restuff all of the paper caps and align it.
