Hi Fellows,

I am pressing need of a schematic for the Johnson Electronic T/R Switch, Catalog no. 250-39.

The one with a 6X4 rectifier and a 6BL7 gating tube.

Or, the value of the button ceramic condenser feeding the output to the reciever  and
the values of the power supply filter condensers.

I'm in a "fix one thing and two others break down" in my boatanchor station situation.

Thanks and any help greatly appreciated! Take care,

Ken   N5CM
