[SBE] RCA Dummy Load

[DanRapak at verizon.net]

All:

I'm looking for information on an old dummy load. I have an old RCA 
liquid cooled dummy load that's been collecting dust for several years. 
It is an RCA  P/N 216251. It's a nice unit with substantial heat fins. 
It's rated at 1 KW continuous and 1.5 KW for 30 minutes. I'm about to 
put it in service in the ham shack. However, I have no manual for it.

My first question is, does anyone know what the frequency range of this 
unit is?

Second, there is a two-pin, military style Amphenol connector on the the 
dummy load. What is the purpose of this connection?

Finally, what is the recommended transformer oil / coolant for this thing?

Any help would be appreciated.

Thanks in advance,
Dan Rapak
