[Heathkit] sb-221 problem

[paul]

amp was working fine. then rig swr went to infinity on xmit when i =
tripped the amp. when i "pass through" the amp without closing the ant =
relay, the rig output makes it through the amp to the antenna no problem =
and perfect swr.. with the relay tripped,no amp output and high swr..  =
tested the rf out and with the power off and when i hand close the =
relay, the output jack shows a dead short. any ideas? i pulled the =
finals and the results are the same. tnx  paul w8jn
