Recently replaced the 4 811 tubes in my AL-811H with a matched quad.
I replaced them because, upon turning the amp on a while back I heard a loud
POP and the amp went dead.
The fuse blew. Replaced Fuse -- same result.
Spoke to some amp gurus around here and said the tubes were probably shorting
out as they were bad - - replace. So I did.
Now when I turn on the rig and tune up I am apparently getting RF into the AMP
as the plate and grid meters move and behave as expected through the tuneup
procedures. However, I show no power out whatsoever from the amp.
Any ideas what to check next? I'm thinking I blew another component somewhere
and plan to take the cover off to see if the smoke has been let out of anything.
