ctc12 clone beam current

My thinking is this

New tube goes in, gets smoked enough to drop the K down due to leakage just enough to screw up bias, Thinks tube must be good since it brand new, etc...


I had Timmy pull the back off a known good set to observe the look of a functioning tube (how the filament changes intensity as it regulates). I warned him of the X ray exposure so not to do this long just see how it should look when working. Needless the say the bad set tube did not behave the way the good tube set worked.
