Yes...
All of the Drake PTO's need a good ground on the slug shft. Dont have a
C version but I think it is the same construction. It was a Drake field
mod if I recall.I think if you google Drake PTO ground braid or similar,
you will get a picture of the mod. A little desoldering wick braid from
the vertical slider to the frame does the trick. I'll send a pic direct.

Hi Mike,
The PTO could well be a poor ground of the PTO shaft. Be sure the
spring is there on the slotted lever that comes up from the shaft and
rides on a rod. The spring holds it against one side but if the rod is
cruddy there's an intermittent ground. A common fix is to solder a
small braid to the top of that lever and the other end goes to ground on
the can, or close by.
I believe the TR-3 S-mtr zero pot is the rear one of the 3 on the side
of the chassis.

First off, I have a tr4 that works just fine, good output, receives
fine, but...
the pto is 'jumpy' as you tune through a station. It doesn't drift. So,
what's the problem?
And,
anyone know where the s-meter zero adjust is on a tr-3?
