Up for sale is a pair of Bent Audio Mu Copper 10:1 ratio S&B TX-103 step-up transformer in like new condition. Comes with upgraded WBT rca connectors. I am the 2nd owner. It was cryo'ed according to the original owner which would improve on sound quality although hard to gauge and compare the cryo effect.
No toggle switch. If you need to use it in 20:1 ratio, it can be done from rewiring inside the can. Lots of info available on how to do so. Or simply ask John at Bent Audio, very nice guy to deal with.
I can include a set of Bent Audio resistors for easy dial-in on cartridge loading at my asking price. Resistor set not came from the original owner.
Very hard to come by and I am hesitate to sell. Paypal please add 3% for fee. Email me with any questions.
