In Reply to: RE: HELP: how do I connect a Tamura F-475? posted by larrymoore@ultrafi.biz on October 21, 2015 at 12:53:38
Thanks! I am blind! Did not see the letters in black until I watched with a magnifying glass.
Now it is clear to me that I will connect Speakers to C and 8 (I tested and this is clearly the secondary winding).
But I still have the same question... where does B+ and plate go connected to? Only E and NF have continuity... so I guess that is the primary winding?
Thanks and regards!

look closer:
B = B+
SG = screen grid
P = plate
So in my circuit, which is a SET I connect B+ to B and P to the 2A3 plate and that's it right?
I have measured resistance and there is 555 Ohms between those 2.
Thanks again!
There's two separate primary windings.
Look at the schematic here:
http://noguchi-trans.co.jp/digitalcatalog/main/tamura.pdf
it shows it all.
This is great info. Thank you! Now it is clear. I will use B and P only!
Looking at this picture it looks like a push pull transformer.
Are the markings the same for the PP and the SE transformers but only one set (B-SG-P) internally connected for the SE transformers?

That is correct. It is a transformer for SE. It is way too small for Push Pull anyway.
