Looking for BIG power resistors
Bill Noble wrote:
the big resistors are common at swap meets here, and the heating element
is still available at some appliance stores (at least I've seen it
there) and also at swap meets- you can just replace the heating element
if you like, nichrome coils are readily available in various
wattage/voltage combinations.
If you want to try a surplus store, try ford electronics in fullerton CA
- they should have some of that kind of stuff - if I remember right the
phone is 714 521 8080

I'm in the process of restoring a WWII vintage transmitter.
So far I've been able to use all of the original parts but some
of the bleeder resistors in the HV supply are bad. Hoping
someone has these in their junkbox;
25K ohm 80 watt; these are 11.5" long and 1.125" in diameter,
ceramic with cartridge type ends. Made by Groves Corp (bit this isn't
important). Need at least two of these.
The other resistor is really one of those old style ceramic floor
heater elements. It has wire wound on a ceramic cone and
uses a standard light bulb base. 220 volts, 660 watts.
This monster is put in series with the primary of the plate
transformer for "low power tuning". Chuckle...
