Anyone know primary output impedance for 6g3? 8k or 6k6?

Looking at Hammond 1760H. http://www.hammondmfg.com/guitarLineOT.htm

Hammond says 1750H is a replacement for Fender 125A1A, which is the PN on the Fender 6G3 schematic. It's a 6k6 primary. http://www.mouser.com/ProductDetail/Ham ... %252b%252b 1760H is same w/ multi tap output. There is a Mag Components equivalent too, http://www.classictone.net/40-18002.html Scroll down for multi-tap and upgrade versions.

I think what he said is, 8K or 6.6K primary resistance output transformer for 6V6GT power tubes.

Good luck figuring out what was going on with the last of the 2X 6V6 tweeds from 1960-62 and the brown Deluxe OTs. I did a lot of searching for a 5G9 project. Seems the late 50s tweeds were 8K, BF were 6.6K, but were the early '60s 125A1A Schumachers just a version of earlier 8K Triads but with bells - who knows?

Anyone got a '60-62' amp w/a 125A1A and bored enough to map it for web posterity?

BTW I went with the BF 6K6 just cause I was bored with 8K OTs. One day I'll get the thing built and listen if I hear anything notable. Seems to me Fender went to 6.6K with fixed bias, but again who knows.
