mystery functions on tuner

Vintage Asylum

Classic gear from yesteryear; vintage audio standing the test of time.

I have an old realistic tube tuner that I got at a hamfest a few years ago. It is FM only and is very basic - it has an on/off switch, a tuning dial, and switch for 'FM', 'FM AFC', and 'PH'. I'm not familiar with this 'PH' function.
There are three outputs - the surprisingly obvious 'output' along with 'mulit' which I assume is an MPX out (which means this is a mono tuner), and 'PH'.
Does anyone know what this 'PH' function is?
Thanks!

I don't think so . . . . - eedork 11:45:31 04/01/07 (2)

Might the 'PH' selection be an input? I have .... - PureAudio 18:05:33 04/01/07 (1)

it's probably a "phono pass-through" - mhardy6647 17:16:50 04/02/07 (0)
