So...the SR-160 can be converted to resemble an SR-500 by changing the finals to 6DQ5s, adding a cooling fan, and a few other changes.?
1.? Could a similar QRO modification be inflicted upon an SR-150??
A pair of 6DQ5 finals in an SR-500 (original or ex-SR-160) with cooling fan would operate with 500 W PEP or 300W CW input? The pair of 6DQ5 finals in an HT-44 operate with 200W (either mode) input.?
2.? Could an HT-44 operate at SR-500 power levels if a cooling fan were added and it were connected to a P-500-AC or PS-500-DC power supply?
I bought an upgraded P-500 at SEAPAC last year and haven't found a use for it yet.
