Rothwell should have one and he uses Lundahl transformers. You might even be able to find one on the pre-owned market at your budget. New might be a little higher but not way out of budget.
SUT for AT-OC9XSL?
Finally looking to get a proper SUT for my AT-OC9XSL cartridge. Does anyone have any experience with a good SUT for this cart? Internal impedance is 12 ohms I believe… haven’t seen many SUTs that mate well with anything but 3-5ohm carts. Any recommendations???? Trying to stay under $300 if I can.
