I've been busy converting the PMR10 schematic to Brit convention. So attached are;
- Model 59 (Brit)
- PMR10 (Brit)
- PMR10 (original)
That original PMR schematic takes a little time to unravel, and I'm not yet sure it's 100% right. It seems to show that the PMR is based on the model 59, but the PMR has the pot ganged with the tuning capacitor and has three resistors mounted in each coil assembly and the values of those change with frequency. Considering that the 59 was highly rated, someone seems to have gone to a lot of trouble to develop the PMR derivative!
