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. 73, Al, W8UT www.boatanchors.org www.hammarlund.info "There is nothing -- absolutely nothing -- half so much worth doing as simply messing about in boats" Ratty, to Mole On 5/7/2011 6:50 PM, mike bryce wrote: > Gang! > > 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.
