Philco 89 (123) (Update-Coil rewind)
#10

Hi Bill,
I found the data, thanks.
I tried to power up the set last night, nothing at all. But I seemed to have a very high voltage on the B+.

Did some checking and founf the wirewound 2 section resistor to be open.
OK, it liiked like broken wires on the form, but that was just string wrapped around.
Still, under the string, I was able to pull a couple of pieces of the wire from the resistor. Here is the part. (Chassis parts 23 and 33) The wire ends had tiny blobs on them where they burned apart.

I think the spec on this was 235 Ohms and 32 Ohms.

I assume I can install seperate resistors, but about what wattage whould I use on this. I have some 2 through 10 W resistors I can make up an substitute unit.

Was there any reason Philco used a wirewound part in this location?

Hopefully it will power up, as everything else looked ok.
Thanks,Gary.
