Speaking of 6J5s, I recently bought a quad of 6S2S (from
this listing) and tried them out in my Glenn's 6SN7 spot, with a Deyan adapter. After 6 hours or so, I noticed the metal XLR end of my headphone cable was hot to the touch, and the amp housing was much hotter than it's ever been (and since switching back to dual 7193s, no issues). I don't see 6S2S's on
@Zachik 's guide (thank you, btw). I'm now also worried about using the quad in my HA-300b - anyone have experience using those on the Glenn OTL?
