hi, have here a valiant ii transmitter without the crystal dummy knob,
to cover the crystal holder,
now in the hole someone put a 6,3 audio female audio plug,
thas can easely removed,
deeper a see a radio tube socket, seems to be original,
question, how do you put the cristals in place,
is there somthing to plugin in the tube socket,
what parts most be present to work with the crystals,
can you change crystals from the frontpanel hole labeled crystals
thanks carlos
