[TMC] part needed

[Telegrapher@worldnet.att.net]

My PSU-500 power supply has an open (wide open!) 80K 50W wirewound
resistor that feeds the regulator string for screen voltage.  I know
everyone has one of these laying around in their junk box right?  Who
would carry such a thing?  Its about 5 1/2 inches long and 5/8th inch
thick.  Looks like ceramic caps on the ends but i could probably get
around that.  Any help?  Was there possibly a mod done to later models
of this power supply that changed the values somewhat to help eliminate
the overheating?  Maybe a 100W unit instead?

Thanks
