I had a bounce as well and on looking at the address, no Japan, so please fix 
your mailer.

The 12A6 is a 12V heater version of the 6A6? 

Try asking vintage radio societies or radio hams and I expect they will know 
where to find the data.

A 1945 publication did not know of the 12A6 under RCA numbers, whilst the 6A6 
in various forms was well covered, and the 25A6 is mentioned. Characteristic 
stated as equivalent to 6N7.
No curves though. 

I would be reluctant to put any tightly specified characteristic on tubes, 
they tend to vary greatly particulary vs. age.

If you are still stuck email me directly.
