Rotary mixer to single ended triode amp

You need an XLR-to-RCA adapter. EBay has them.

Yes. I was actually looking for recommendations for specific brands of high quality interconnects with customizable terminals. Preferably ones people have had success with. Thanks again. 

Monoprice makes good quality xlr-rca cables 

Thanks @chayro. I ended up buying two different cables for comparison. A cheap one from Cordial and a pricier one from Cardas.

Zavfino cables are excellent and they have cables to suit many budgets

I prefer cables that use UP-OCC copper or silver
