Ah, always seems to be something. But at least the trouble shooting is going in the right direction.
I replaced all trim pots in my amp some years ago and it really helped stabilize any measurement readings.
The octet of power tubes in the set I purchased consisted of 7 6550 Winged C and 1 6550WE. They are all matched extremely close and I believe originally came from ARC. Due to availability I suspect they chose the best options available to make up the sets. That may explain the different tube brands you likewise have come across.
Glad you are able to use the KT120 instead of the 6550's. That is a lot of tubes and I can only imagine the heat. I only have 5 6550's total and it is indeed very hot. Unfortunately ARC says I cannot run the KT120's in my amp. It would have been nice to have that option as tube supplies diminish.
While doing some research on your amp I came across your rebuild on another forum. I don't usually spend much time anywhere other than Audio Asylum but looks like you've been at it for some time. I admire your passion and especially your patience. Quite the journey. Thank you for sharing some of it here.
