Jacques, your guess was correct, pretty clever thinking.
Thank you for replying to message with your help.

C9:
It was labeled NTK 112K, only have a multimeter and it measured open (no charging).
Replaced with a 100pf/3kv ceramic.
C4:
Since already in area, replaced C4 also. It was labeled NTK 302k.
It seemed to charge up with meter but very quickly.
Tried to replace with a 470pf (close to drawing) but didn't work good.
So replaced with 330pf/3kv ceramic,, it works.
It is way tight area under the PA box where switch is, very difficult to work in.?
Fortunately the new caps are much smaller than the old ones, giving some extra space.
I have acquired a complete Elko-cap replacement kit for the radio and will later start replacing all the elko's.
There are what looks like qty>50 elecrolytic caps in the kit, will be a big job. Probably work one section at a time.

The radio is actually an ZSD model for 10W output. from Japanese market? It's same radio otherwise as the ZD
Now have the PA board for twin tubes and am considering altering for 100W.
Radio is in excellent condition.

Thanks again!! :-))
