Philco 77 Resistor
#1

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
