Hello All,
Now that I have the PTO aligned and stable its time for the next round. Does 
anyone know of a 'known to work' schematic for an R-390A product detector? 
Either something solid state, something that uses a 6BE6 or one that uses 
the ballast tube socket would all be interesting to consider.
Thanks All, 73,
Keith, ve3ts
