(I like to sleuth odd tube types): At: http://www.tubedepot.com/ts-ef806.html

you can buy one for $37.00+ It's like the 6267 and I find data on that one at:

http://tdsl.duncanamps.com/tubesearch.php It's like these: 6F22, CV10098,

CV2901, CV8068, EF86, Z729. It's a low-noise pentode with base pinout B9A

At: http://www.vacuumtubes.com/6267.html you can pay over a hundred bucks

for one or a similar tube A cross reference list I have shows the tube base to be

9CV and shows these other tube with the same base:

6BQ5/EL84 (miniature pentode with pinout 9CV)

6267 7189 EF86

6BQ5 7189A EL84

6BQ5WA 7320 N709

6P15 E84L Z729

Of course some of these are not the same sort of tube at all, they just have the

same pinout as the 6267.

Thanks for the tube info. I need to run it through one of tube testers or ck the

pinout for the filament, which I think is NG.

This likely was before WW-II: I don't have any examples of that convention. It's

back. There is a growing trend in EE and Electrophysics to consider current as
