Thanks for the encouragement. I've almost decided not to try to repair it
but to build a modern, solid state oscillator using the mechanical
components as the basis. The dual variable capacitors are an almost
impossible item to find and there's more than enough space in the chassis
for anything with transistors or IC's. And, as a bonus, the bottom of the
interior foundation should serve to isolate the incoming AC from the
sensitive circuitry in the upper compartment.

I'm sure that with Jim William's help you could do a good job at this,
but the 200CD was really a very nice instrument by the time HP
discontinued it. I think it had a nearly 30 year lifetime, during
which it got many significant upgrades. If you have an early one,
there might be some reason to "rebuild" it, but I suspect that it
would be hard to do better than the late versions. Plus it would take
a lot less time to fix than to repair.

I have some NOS 200CD replacement parts here (caps and light bulbs.)

If you send me your serial number I can tell you how early or late
yours is.
