Requesting help with vintage Marantz tuner.

[jaffy]

Hi, I just found a vintage Marantz ST325 tuner for a good price ($2 ), and I want to integrate it into my current system. Only problem is that it uses a non-standard power connector. It looks like a 3-prong molex, and is labeled:

Top connector: GND
Middle connector: 15.6V - 120MA
Bottom connector: 11V - 50MA

I suspect that it was designed for use with a Marantz amp. Is there any way to power it without the associated equipment?

You are correct.... the tuner you have was part of a set.
It plugged into a PM225 Amplifier.

Excellent, thanks! I've been looking all over and couldn't find any info anywhere.
