what would cause an amplifer to draw a small amount of plate current for a few seconds after you unkey the amp. I noticed today that my alpha 77dx was drawing about 100ma of plate current for a few seconds after i unkeyed the amp. i had been running it hard for about 10 min. after i let the amp cool for awhile it no longer drew plate current for that few seconds after i unkeyed. Seems to do it when the amps been transmitting for a long time.? Also it only did it in the SSB position. when i put the amp in CW the problem when away.
