  I have a R390a Serial @ 163.  Problem is turning on the BFO looses all output.  Rx is ok all bands with BFO off.  I have a manual for thr R390a but I guess mine is an earlier model.  The BFO in mine is nothing like the schematic.  Mine has a small relay that is switched on by the BFO switch.  I don't think this is any kind of mod as it looks factory wired.  The BFO circuit is also very different then the schematic I have.   The rig was given to me and I would love to see it work again properly.  So far I've had to change the 17 mc crystal and a few tubes to hear it work again.  Anyone have a schematic with a relay in the BFO switch?  73 Rich
