Hi, im looking for a test point to check voltage coming from my internal power supply on a trc-457. Can anyone confirm if i test one side of r302 as im not having any luck. Im using the chassis for the neg lead from my meter. Thx in advance
It's test point 10, the emitter of TR401 at 13.80 vdc. You can also measure it at C94 on the board but use a transformer can or the metal dividers by the PLL section for ground as the chassis and the board do not share ground.
