Mystery module/hybrid - Page 2

No, I would like to say they were very expensive but RCA gave
me five modules for testing in 1973 which in return I give them data from the tests.
I still have three that I found in my junk last week. I think the other two were destroyed in the tests.

The 2500 was the 'hi-fi' version of the 2000. The 2000 had fixed bias and flyback diodes across the outputs. Same package I think.

Wow another blast from the past. My old Heathkit AR-1500A receiver of early 70's used almost the exact same circuit. that Receiver was rated at 60 Watts RMS Per Ch @ 8 ohms and 90 @ 4
