I am looking for some technical data on the following Heathkit TR relays:
69-21     TR relay, 4PDT, Used in HX-20
69-35      TR relay, 4PDT, used in HW-100, SB-100 and others

I would like to know:
Coil Resistance
Coil Operating Voltage
Plus where I can get some!

My guesstimate at this time is that the coil operating voltage is 120
VDC to 140 VDC (need to find out if AC coils are ok) with a typical
resistance of 6,500 ohms.

I have done web searches but have not found much. I did find one source
for the new equivalent 69-35 relays. Some references to sources on the
old Tempe list but computer couldn't retrieve them. Knowing these
pieces of data, I should be able to poke through catalogs and find
sources.  

Thanks to all
