It appears that, I stopped this thread in its tracks…
Unfortunate, I always look forward to a lively tube discussion, especially 12AU7 variants, which my preamp utilizes, to great effect, in its gain stage
Meanwhile, if you get a chance at a pair of these, jump on it. They provide all the goodies in spades!
If I recall @vkennedy61 has a pair, or maybe the Siemens branded chrome plates in his VTL. Same flavor…
Best,
