I had a similar problem with the flat loading capacitors plates burning
a hole and failing on my Drake MN-2000 ATU and found some very nice low
profile 200pf 10KV mica transmitting capacitors from Bulgaria on eBay
for $6.00 each. There seems to be a good supply from the vendor as they
are currently listed as:

2 200 pF 10kV LOT OF 2 HIGH VOLTAGE CERAMIC DOORKNOB CAPACITORS KVI-3
(???-3)
Shipping took only a week and the items fit inside the tuner easily. I
used some tinned solder wick to make the connections to the switch as I
did not have any tinned braid available.

I have an MB-V and an MB-IV.
The MB-IV experienced a fixed capacitor failure. There is a stacked capacitor bank that was fabricated by Nye
using insulating sheet separated by metal plates. One of the insulator sheets
broke down.
I repaired it myself by unbolting the stack, cleaning up the affected capacitor plates, and replacing the insulator with a piece of teflon sheet that one of my friends happened to have.
So far so good on the repair, but I don't need to use the tuners much these days.

What is the model number....there is not to much that can go wrong with
them. You might check at the switches and coil for any bad contacts
which normally if not burned can be repaired with a pencil eraser or
some very light emery cloth.
