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
