I dident say but the driver tube can be a 6SN7 or 12SN7 or 25SN7 / 1633 / 13D1
This allows for more driver tubes to be tried I was useing it with a Ken-Rad 1633 on the 25 volt setting

I wasn't planning on doing this on your amp cause I thought you were good
with the BL63.
But I can do this in your amp no problem Just add a voltage quadrupler and a three position switch.

Well, there is silence in my listening area for now.  I decided I was sick of fixing cabinets and windows and painting walls and decided to listen to some music last night only to discover my OTL amp somehow got damaged during the move.  It got to ride on the front seat of the car and never got bumped so I'm not sure how this happened, but she's out of commission now.

To frame the situation......  It's not physical damage but a malfunction of some kind.  With the volume on steps 1-5 only the left channel works with the right channel dead.  Once you click the volume pot to step 6 it gets interesting, the left channel goes silent and the right channel comes on in its place....... completely unattenuated (at maximum volume).  I have tried the usual trouble shooting steps such as trying different tubes.
 
Logically it would seem to be that the volume pot has mysteriously gone bad, but I will wait for the expert himself to weigh in with his thoughts.

Perhaps, a loose connection... whatever this challenge turns out to be, it's nice to see you at once in a new space (living) and this space (visiting).

Had the volume control got bumped and pushed the shaft back in the switch a little??
Can You take the bottom off the amp and look at the switch and see if a ground wire came off
or something??  Then let me know what you see.
