Stereo Cart to Mono Pre Amp

[vasu]

My project: MC preamp only one channel (mono) , Moving Coil Input Transformer, tube preamp and passive riaa.
My cartridge is Audio-Technica AT-09 stereo MC. Phono cables together or what? Input impedance should be 1/2 ?

Hi,
I would try paralleling the cartridge pins and then feeding into half to full impedance value.

You may find that the impedance needs altering from the recommended anyway.

I paralleled the cartridge outputs and used 24k for my mono record player. It seems fine.
