Re: Phase Track Liniplex F2 receiver.
The outboard power supply unit for the Liniplex F2 is simply a transformer that provides a nominal 15-0-15 volts AC, although that will vary according to the supply source, and I’d guess was based upon a 230-volt input. The supply voltage switch is on the receiver itself, and appears to switch between half transformer output voltage for the 170 to 265-volt case, and full transformer output voltage for the 90 to 170-volt case. The rectifier and battery charging circuitry (for the internal nicad cells) is within the receiver. Alternatively, a set of regular cells may be used as long as the power adaptor is not connected.
I could retrieve my F2 from storage and measure the voltages on the power supply unit pins, if it is still working that is. But that might take a little while. I think that one could work out which power supply input pin is which by looking at the unit itself. One 15-volt pin goes to the fuse FS1. The other, and the 0-volt pin, go to the voltage selector switch.
Please let me know if you want a copy of the manual.
