MHDT Orchid TUBE ROLLING

6922 on top of converter will go through the cut out of the top plate... unlike the 6sn7 whose diameter is larger than the hole in the top plate, thus running that tube w converyer you need to run without top plate or enlarge the hole

but the 6922 with converter plug will sit tall, will protrude up far above the level of the top plate by 2/3 of the glass envelope of the tube

I tried the 6SN7 with the converter in my Orchid and did not care for it. No experience with the 6922.

Tube Depot has the we396a 1958 “D” getter just in.  Or is it a Western Electric JW2C51?  I ordered one.  Let you know.

Curiosity Question
                             I have a DAC and Phonostage using E88CC's.
How does the 6SN7 find a usage in a Circuit that can use the E88CC, 6922, 6n23p Valves.
I would be keen to learn about this as an alternate option for my own trials.
