   I said something like: `Switch to XTAL W/O any crystal, operate and work the plate tune and 
loading, ANY power in to your test load means it is osculating.'  A positive test!

   And:  `The driver|PA shield must make good electrical connection to the chassis and a lack 
thereof will result in osculation.'  (I had to solder the shield down in my DX-100 because it 
osculated until I soldered it down and both are copper plated.)
