Greetings everyone!
I recently was given a Philco Model 77. Cabinet is in great shape, almost looks new. I am going to replace all of the capacitors and that shouldn't be too tough once I get past the tar. My question is in regard to one of the wire wound tubular resistors. The shorter one is a two-stage affair and the 800 ohm winding is open. Looks like someone was into it before me and about half of the winding is missing, so even if I could re-connect, it would probably be the wrong value. I was thinking about attaching a power resistor between the lugs and was wondering if 5 Watts would be sufficient, or if I should go higher? The schematic makes reference to all resistors being 1 Watt, with the exception of the two wire wound jobs.
I was also thinking about rewinding it, but not sure what type of wire I should use or where I may obtain it.
Any advice would be appreciated.
Thank you and regards,
George B. Reisdorf
