hi keith,
yes it does, all clear now,
the power supply here delivers all voltages needed for rx and tx,
its has even an audiostage build in with speaker volume bass and treble,
so the audio output from set 19 is also delivered to the audiostage of the power suply and is working,
the volume pot works also on the 19 set,
no phones are connected at present time,
so this can be the reason, i suspect that headphones should be connected to the 12 pins pye output connector since i see no other6.3 audio ouput connector on the set,
will search for the output pins and connect a headphone to it(if i cand find them on a schematic.
