Uniden PC-383 AB schematic and service manual anyone?

[Robb]

Local operator dropped off his President McKinley radio for me to give it a thorough tuneup.
It works, but it also needs an alignment info in the SM.
Never worked on this model before, so what files do you have for it?

ALSO: need the procedure for the clarifier unlock.

Thanks!!!!!

sorry just saw the board number.

this is the mobile version of the 142GTL/ Washington, and is a single conversion MB8719 chassis.

you should be able to use the service manual for the Teaberry Stalker IX:

also check out the service manual for the Stalker XV, as it is the base version that is like the 142GTL.
if you find problems with one manual, check the other. there may be differences im not thinking of right now.

For the clarifier mod, it said to remove D36 and R187; then reroute the red and orange wires to +8v from the MB3756 reg.

I looked for R187 and my dumbazz can't find it. Noticed some of the resistors are not marked on the board.
Can anyone give me a clue please? General area or specific is fine.

Signed/'Clueless' . . . lulz
Thanks!

Robb,
It is here on the schematic. In the chassis??? Center wiper of clarifier to emitter of TR45 via R201 (3.3k ohm). Appears to be a 22k ohm. That may help narrow it down.


Full schematic attached.
