HI Vic: True... you probably could brew up an amp for less money. Looking at the commercial market, there is an Ameritron amp for $800.. which includes the power supply, too. It uses 3 type 811 tubes. Now... it's rated at 600W PEP with 100W drive. So, with 10W drive, it's output would be well less than 100W most likely. But then... it wouldn't be an Elecraft amp. And it doesn't work on 6 meters.
While the new Ten Tec amp requires a DC power supply, which would be an extra cost for base station use, it does work on 6 meters and it quite compact. I suspect that the KXPA3 will be priced in the same ballpark. Both the Elecraft and the Ten Tec amps would work nicely as mobile amps, since both will have frequency sensing, meaning you could mount them in a vehicle trunk or similar out-of-the-way location. 73 de Ray K2ULR On Aug 12, 2012, at 12:39 PM, Vic K2VCO wrote: > If a 100w amplifier has to cost $800, then it is going to be > difficult to market.
