I've been looking at my assortment of scavenged step-up transformers, and it looks like a range of 1:15 or 1:16 might be suitable for both my AT MC Cartridges. I have a pair of Beyerdynamic 1:15 transformers, a pair of McGohan MC-2s, and a pair of Cinemag CMQEE-3440AH that may fill the bill. Comment if you have experience with any of these. I plan to use them into the input of my current phono preamp into a ~50k load. It looks like the Hana SL I have would be best suited with a 1:10 step-up ratio.
Hi, I also just got a UA-7045 which I intend to put on a diy oak armboard on a TD125 mark I. Could someone please elaborate on how to replace the arm wiring and whether or not it is possible and advisable to upgrade (or polish) the bearings?
Thanks in advance for any advice.

The bearings are not your typical pointy screw in a cup of balls. This arm uses minature precision ball bearing assemblys, the assembly has an inner race, outer race and bearing balls like you would find in an electric motor. Don't mess with them unless they are corroded, in that case you replace as an assembly.
What makes you think the wiring needs replacing. I have several of these arms and have never had an issue.

Thanks. I thought it was almost standard practice to rewire with thin 36 Awg wires with vintage 40+ yr old tonearm’s to get more detail retrieval.
