20 watts clean!?
I put the transmit amplifier chain together yesterday - two 2N2219A stages followed by an IRF-510 stage to get the drive level where I needed it for the dual RD16HHF1s.? After adjusting the RF gain stage I am getting 20 watts clean out - which is a bit more than I expected.? The input drive level range seems to be fairly narrow and the amp runs a bit warm. Skelton has the bias on the RD16s at 500mA.? I may try reducing the bias and see how things shake out.
