Hello all,
I am starting on a Philco mod. 50 and have a question about cap # 15 on the schematic. It is a metal box with 5 leads. The schematic gives the values as a group(.1, .15, .25 2-.5's) but not as idividual values. The schematic shows all the # 15's but I can not find where the values are identified for the specific caps so I can trace them back and know what goes where. Thanks for any help.
Merry Christmas and a happy new year to all.
Jon.

You may try a couple of things: 1. Measure each value with a capacitance meter (remove the individual wire from its' connection) 2. Use .5 or 1 uf for all since bypass caps are usually non critical and see if it works normally. 3. contact the Philco repair bench linked to this site. 4. Have a great Christmas.

Hi Jon

Use this schematic:

At the bottom capacitors are identified by numbers and wire color.

Norm,
Once again you are the MAN! Many thanks and Merry Christmas.

Jon,

Look closely at the picture Norm sent as it shows the value for the cap.

I rebuilt one on a Philco 71 recently and I marked each wire with the cap value. I cut the wires to the can and removed it, Pryed off the end cap very carefully to keep the tabs from breaking and removed the internals.

Then I mounted the new caps inside the can (using the schematci for the #15 can as shown at the bottom of the schemactic)and used various color wires to indicate value to match up with the originals. After re-assembly, the whole thing looked like it was new.

Terry,
Thanks for the info. For some reason my schematics did not have the cap diagram. Once I got them, it was a snap to restuff the original can by just the method you describe. I just have to recone the speaker and it is done. I am surprised by the sound quality and volume from this TRF set even with a shot speaker cone.
Merry Christmas.
Jon.
