My ancient Kenwood TS520 is starting to show signs of age.
The plate current drops off slowly when the carrier is switched on. Also cannot achieve full load anymore.
Methinks that the finals (a pair of 6146's driven by a 12BY7) are getting tired for the first time.
I do not have an oscilloscope for neutralizing a new set of tubes. Does anyone have a method of doing that with a non-scope situation?
