[VHFcontesting] AM-6155 PS Question

Fri Dec 9 21:23:19 PST 2011
Hi All: I decided to blow the cobwebs out of my AM-6155 amps that had not
been used in 20 years. I have HV ok on two units but the screen V is low on
one (275V) and not present on the second. I will check the screen dropping
resistors and Zeners tomorrow, I'm just curious if others have run into
similar issues..... Actually, not having the HV caps go BANG on start-up
after 20 years was a pleasant surprise.... Mike wa3tts
