BTW NEVER measure the plate of the 6LB6 OR the damper unless you like
fire trucks. Your meter will go up like a Tesla !
BTW #2 the HV regulator ( 6HS5 or 6HV5 ) must be matched with the
right damper tube. Look for tags on HV box or layout chart. Wrong
pair will work BUT not right & not for long.
Good you are taking it slow....

Will a dead tube still light or no?
