I had the same problem with the Svetlana 6550. I think this is normal.
New to tubes.
I own an ASL MGSI15DT that I bought on Audiogon a few months ago.I've noticed that the last few times I turned the amp on,one of the 12ax7 tubes flares up inside
the bottom of the tube.I'm not sure of the age of the tubes.Is this an indication that they are starting to go,
or could this flareup be a sign of an internal problem?
