[Milsurplus] GRC-215

I am finishing up on reverse engineering the PA for a GRC-215. Does anyone 
have info on this set? It uses a pair of 40 Watt transistors in the PA. The 
driver takes 500 mW. It appears to be segmented into 4 bands. The input top 
the PA has a circuit that appears to linearize the input so that the PA 
puts out the same power across the band.

The PA is fed 24 VDC via a rather small, about AWG 24, wire. The 
transistors are capable of drawing 15 Amps when driven to full output (from 
the transistor spec sheets). It appears from the size of the wire feeding 
the PA that it produces significantly less than maximum power. What was the 
power out for this amplifier? What would the ALC voltage be?

Any help would be appreciated.

Thanks
