Don,
Glad I was able to help you with your problem. Depending on how your connector
opened-up I could see the 8877 being damaged,or not being damaged. Lets just
keep our fingers crossed! Glad to hear the AL-1200 is doing FB job...maybe I
shouldn't have let that amp get away. I do not know Bruce Lykins but maybe
someone else on this reflector might know him and be able to help you.
Best 73 and Holiday Greetings,

You couldn't have been more right! Pin 4 of the molex has the solder
melted off the connection and is very flaky. Now to find (or make) a molex
remover and clear up the problem. My other question - what has this done
to the 8877 (s) if anything. Nothing good, I'm sure but I will likely find
out in short order. I just have the one spare 8877 unfortunately, but
that's better than none which was the case all summer. But not for lack
of trying! Do you, by chance, know a Bruce Lykins in Florida? We had a
trade going to get a couple of 8877 pulls but I never got the tubes and
his e-mail doesn't seem to work anymore!
BTW, the AL-1200 is running just fine and has proven to be a good contest
op with the rather non critical tuning and all.
Thanks again for the right on advice.
