Chewed up my first KT90

Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

These were comfortably running in my W6m's, with 2W/10R cathode sense resistors. Flash of blue and the some smoak issued forth as I was reaching for the power switch( was right next to it, fixin' to swap in another disc). Rolled the amp over and found that cathode R was crisped, and to do that I assume I had some sort of internal failure that resulted in the blue flash. These were from Jim's last good batch of Type III.

Off to rehab, though my only good set of replacements is a set of Type II's.
cheers,
Douglas
