DE ED, KI6DCB (Seventy-two years old and off-air until I build a new shack with acres of antennas (antennae? HI HI) ready to go. I'm going to be using Icom's excellent IC-275H, IC-375A, 475H, 575H, and 1275A on VHF and UHF, with an old Kenwood TS-940SAT and a homebrew, dual 4-1000A, Class A, push-pull amplifier. Going to TS-990A and SDR soon, all for HF.)?

Eimac data sheet does show 890 watts out, but the plate voltage needs to be 3500 at full load. The AL-80 amps do not have this much plate voltage. Unless you¡¯re a CBer on 11M. Hi hi

also, in Class C the driving power and peak grid-cathode voltage will be higher. ?my home brew AM transmitter runs a pair of 1625s modulated by a pair. The RF deck runs a pair of 1625s in class C but the modulator runs a pair of 1625s in class AB1 push pull.?
anyway, happy to see everyone interrested in this topic. Nice to see people engaged, even if some comments have the posters not exactly in the ball park. Very entertaining!?
