I’m interested in integrating a step up transformer into my tube phono preamp. If anyone is looking to unload a pair of SUTs in the 1:6 (15dB) to 1:10 (20dB) range, please PM me.
My budget is flexible depending on what you have available.
U.S. sourcing is strongly preferred, given current international shipping challenges.

I have a pair of Sescom MI-8 and pair of Sescom MI-52...dont remember the SU ratio. I think the MI-8 was 150 ohm - 600 ohm (4:1)
Found info on the MI-52
Specs:
GN - GN/ WT 50k winding. (6k4 dc)
BU - YE. 400 ohm winding. (35 ohm dc)
BK - OG. 400 ohm. (32 ohm dc)
From BU & BK tied to YE & OG tied is 26 dB @ 1kHz
From YE to BK with BU/OG tied is exactly 20 dB @ 1kHz
