RE: stereo, single ended phono pre used in single channel balanced mode?

You would need to add two more 47k resistors in series across the mono cartridge output with their center connection tied to the ground of each phono input. That combined with the phono stages internal 47k resistors would load the cartridge with 47k. If you didn't add the second set of 47k resistors the cartridge would be loaded with 2 x 47k = 94k Therefore, by adding a second set of 47k resistors it might just work. The output from the phono stage would be in-phase for one channel and 180-degrees out-of-phase in the other channel providing a mono balanced output.

I think it might work. You can try it and see if it works.

Good luck,
