You might want to try the Hot Foot keyer. I've never used one, but it looks like what you may be looking for. Just like the previous post stated, you will need 100 watts to drive the amp. A small 2 pill in low power should do the trick. Expect to get about 600 - 650 watts P.E.P. out on SSB. The amplifier was not designed and not recommended for AM operation. Somebody please correct me if I'm wrong in my last statement. Something about the duty handling of the 572b tubes and heat problem.
they operate well on am also........ maintain a peak-carrier ratio of 4:1 or so and you won't have any problems. 125+carrier to 600 - 650 pep on am and 650 - 700 pep on ssb. Tubes are 2) 572B/T160Ls.
greeaaat amp i had one a long time ago.I recomend you slide it out of the green shell and take the cover off the rf deck.Make sure its unplugged.Short the tank circuit to ground with a screw driver.Make sure the tubes are plugged in all the way take a look at the relay on the bottom.Look at the contacts to see if they are burned up if they are replace it.You may want to clean them while its apart. When you put it back together make sure the fan works.Jeff over at harbach sells all sorts of parts for that amp. Im not sure if the bandswitch is still in it but if abused the contacts usually fail.If they do you can just bypass it.That amp should do 800 pep easy it will key 200 and hold it.
Sometimes the existing tank coil will tune to 11m but usually the efficiency is not that great. A simple repositioning of the 10m tap on the coil is all that is needed. Some [slash] butchers[/slash] operators remove the tank coil completely and replace it with a home made coil for single band operation on 11m.
