After pulling the E-6SN7 Linlai from my system, I'm back to my typical setup. Amp; K-R black glass VT-231 in gain stage, Sylvania VT-231 as follower, and Sylvania 6SN7GT 1952 bottom-getter as driver/phase inverter. Preamp has Tung-Sol VT-231 round plates.
I stocked up on Sylvania GT bottom-getter 2 and 3 hole plates (Bad Boys) as prices started to rise. Also have a couple pair of WWII VT-231.
