@rocray thanks for the break in info. Mine are on the way from China and will take time to arrive. Will update their progress as they break in. Previous Don Sachs Model 2 linestage owner set it up with two gray glass RCA VT 231, two Ken-Rad black glass VT231, and a Coke bottle Sylvania 6BY5GA rectifier. If Linlai can match or beat this and have a long life, I'll be thrilled. Looking forward to your break in updates.
How tall are the Linlai? Hope they aren't taller than the Sylvania rectifier. It is twice the height of a standard 6SN7.
Thanks,
