Audio Research PH1 modification
 
I have an Audio Research PH1, it is for MM cartridge. I dont have the schematic, but I want it tobe able to receive MC cartridge. Do anyone can help me on how to do it? I search the ARC website, but they do not provide any email to contact them, so I hope maybe someone can help me.

Use some quality step up transformers from someone like Lundahl or Steven and Billington. They can be added in a small box externally.

I think the MC version of the PH1 uses a pair of JT-346-AX-1 step-up transformers made by Jensen Transformers:

There are probably holes already punched for fitting it...
