Philco 41-285 wiring issue

[jr_tech]

OK it sounds as if the solid state diodes are working ok and producing a decent B+ voltage for the set as measured on the cap. Now this voltage passes through the speaker field coil (part #60 on the schematic) to a second cap (part #27a on the schematic) the second cap should have about 180VDC or so between the + side and chassis ground. If that voltage is not present, it is possible that the field coil is open.

If you can't locate the second cap take another picture that shows a bit more of the wiring, and I can try to spot it.

Does the speaker plug in to an outlet on the chassis or are the wires just soldered to the circuit?

I can almost hear the music! You're making great progress with jr tech's help.

ALL RIGHT!!

I am starting to really follow along. Thanks man.
I think I haver located it here on the drawings...but not sure location in the chassis.
Are we talking about the other bigger electrolytic..since we are talking (+) sides of caps?

[jr_tech]

Yes, It is the one that you have indicated with the "smilie" face on the schematic. It would be an electrolytic, perhaps a metal can on the chassis, or perhaps similar to the the one the diodes are connected to, under the chassis. Perhaps if you took picture that shows more of the wiring, I can spot it. It could be the one that is right next to the first cap, but I can't tell from the picture what that cap is connected to.

Great.
I will take a few pictures and post them tonight.
thanks again
