More PA Putzing ..


 

So ..Thinking of this and that ...Came to the blinding revelation that the IRF150 is NOT a current controlled device, but a voltage controlled device ...With that in mind, I bypassed the main current drivers in the pa Q92,93,96,97 and connected directly from T9 to T11...Circuit alterations in pix as well as sweep of PA pass-band ...Output seem on the order of 5 watts ...Spur checking tomorrow
