If you read my post carefully I said OWNED . I did not say BUILT. The amp
was built by W7JNC, if I can remember this correctly. In the same Radio
Handbook is " A DELUXE MOBILE TRANSCEIVER" also built by W7JNC. You will
see a very close relationship in workmanship of the 2 pieces of equipment.

Oh, LOTS of folks can and do build amplifiers.
