First I have a Mc Gregor R60 superhet sc receiver, I need info as to what crystals fit, ie: does it have the early unusual i.f. frequency or regular later standard?

Secondly, I have an unidentified superregen receiver 27mhz , As the relay is samped OS Japan , im asumeing its an early OS unit.
also anyone know what voltages these use?

Not sure about the first one Stewart but the Blue aluminium one is almost certainly 470khz IF frequency. 470khz below tx crystal.

Thanks Ron, I suspected the McGregor had a 470 if , you wouldn't know were I might obtain a set of crystals?

Hi Stewart,

Here is wiring diagram for my RS-1 superhet Rx which most likely has the same relay - max 6v/1A
