Heathkit - SB-200 Problem - Help!
"Roger Basford" wrote in message
... I'd say, that as it was working fine on the lower bands, there is a good chance that the neutralisation wasn't set right for Ten and the amplifier went into self-oscillation, destroying one of the 572s. Roger/G3VKM Being a cathode driven amplifier, Heath did not use neutralization in the SB-200. My best bet is a bad switch. 73, Barry WA4VZQ |
