I would think that the Alpha microcessor is pretty basic and looking for simple analog inputs. Much like an automotive processor. I had a built up LT1/4L60E Corvette combo in a 38 Chevy coupe and the

It sounds as if it may be a reactive dummy load for performance testing the specs of a TX or small amp. But is there any switching of jumper options? The resistors should be non inductive, maybe Dale

If you dont need 160 the SB-200 is an economical choice. They work fine on 12/17M also. It is not an amp for RTTY or digital modes. The price stays low since over 10,000 were sold. I buy around 50 a

1KW input on CW, 2KW PEP on SSB was the FCC reg back then. For that reason many amps of that era had a CW/SSB plate voltage switch. Many left it in the SSB position irregardless of the mode (; No sen

Your slight technicality is a later revision to the regs, the FCC was having a problem defining the power so that advertising wording and tuning instructions didnt break rules. In 1963 1000W DC input
