Thanks all..I put the amp up on the bench today and heard something
"rattling" inside as I carried the amp. Upon further inspection the rattle
was the remainder of what looks to be one of the grid resistors.
Not sure how many I trashed or if it took the tubes with them yet. Its late
and that's another session at the bench with the elmer....
