Hi-
I've a Dynaco St35 with original transformers, but rebuilt with Audio Regenesis boards and the Gillispie EFB Mod. I bought it already modded, but I re-tubbed it. I bought JJ driver tubes and Genalex Gold Lion re-issue EL84 power tubes bought as a matched quad. Not long ago, one channel sounded scratchy, and today, the plate in one of the power tubes turned red hot upon startup, so I shut 'er down right away. Before I put in new tube/s (I've an email message into Jim McShane already), are there any components on that board that should be checked that may have damaged that tube? All I have is a volt/ohm meter.
