Wanted: SUT to suit Denon DL103

[surayne]

I’m looking for a step up transformer for my second system which will go between a standard DL103 and a World Audio Phono 3. Budget is around £200. There is a small chance that I might use it with a 103R instead so adjustable loading would be ideal but not essential. I'd be particularly keen on an older Puresound T10 (mk 1 with the dial on the back rather than switches).

This Fidelity Research FRT-3 is still available I think: https://theartofsound.net/forum/show...arch-FRT-3-SUT

It's perfect with the Denons and sounds amazingly good.

I have a Beyerdynamic SUT (1:15) bought on this forum (together with a DL-103R) which I no longer need.

Now sorted with a T10, thanks for the offers.

The key for the 103 is primary winding inductance.
Hopefully it's more than 2H , otherwise the bass will suffer.

The primary winding inductance for the Haufe T-7883 transformer is ~ 1H (actually it is quoted as an impedance of 6.8 kOhm at 1kHz, which translates to an inductance of 1.08H. I have ignored the winding resistance as it is much less than the inductive reactance).

The coil resistance of the Denon 103 is 40 Ohm, placing the low frequency -3dB point at 6.4Hz.
