[Boatanchors] Johnson Viking I questions

[Carl]

Id replace any paper and electrolytic cap, the originals will go south 
pretty fast after applied voltages accelerate the chemical action.

The PTT can be found in that Mod section you mentioned, or in the Viking II 
in the CDC model.

Im guessing that Mod A is the 829B swap for the then unobtanium 4D32 during 
the Korean War.

I use a I and II CDC regularly.
