My stereo corrector (834P with air-vane caps) has a shorting switch across the two channels at the input. I suggest you incorporate the same.
With it out of circuit I did indeed get that hum you refer to with the SPU Mono. Switching to short eliminated it. |

I see, it is exactly what I thought. So, you short the “hot” between two channels at the input? It is already shorted on the cartridge side but you shorting it locally (on the corrector side) kill the loop across the cable. The same effect might be archived if we drive signal from SPU via one cable and then split it on the phonostage side via a switch or having a switch on outside of the corrector feeding right and left cable. It looks like your solution is less painful… Oh, well, not I need a switch and to drill a hole… I will need to learn to disengage the mono switch. I wonder if other options are available… for instance to shunt the RCAs on the cable that feed signal from SPU. Then it will be still bridge locally and the loop will be not 120cm but a few millimeters.

Something similar to what you have, mine is combined with ET2 transformer.
