[R-390] Product Detector

[Judi Doran]

You can also check on the plug in product detector manufactured by Universal 
Service for the 75A2. it is a two tube unit, I have one and schematic. It 
sure looks like it could be easly converted to sync det by feeding the osc 
some carrier. schematic is online.  Bernie W8RPW
