Hello,
Question is where you want to use this. Is it just going to be used as a voltage amp or ??
This chart might help some.

There are differences but nothing too glaring depending on use.
Guess another question is why when 6EJ7's are so cheap ??

My understanding is you never want to use a semi-remote cutoff tube in audio service and the 6EH7 is one.
Thanks,

Hiya,
I know its the exact sub but have you given either Mullard EF184's or Phillips EF184's a shot. ??
The mesh plates are pretty darn stable I have found.

The 6EJ7s I run are not microphonic.
Hiya,
Straining my brain to remember what type I hated and it came to me.
The ones to avoid are the Swiss Cheese looking grey USA made punch plate's
Maybe fine in a 1968 Zenith Color TV but they have sucked (For Me At Least) almost universally for audio use.
