Hi John, the B7G plug will be gratefully received.

It's a very easy task to remove the chassis from the cabinet. Disconnect the loudspeaker leads, the five control panel plugs on the left side of the chassis, remove the two 2BA hex head chassis securing screws and withdraw the chassis complete with the CRT.

Only one waxie found in the frame timebase, C96, a 0.2mfd TCC component - and it's leaky. The cathode bias capacitor C97 500mfd is OK but the PCL85 screen grid decoupler C98 might be suspect.
Lots of black tubular Hunts capacitors to check for leaks.
The attachment shows the circuit diagram of the model DR39.
