Anybody know if there is a voltage adjustment on the RS-35M, if yes, where? Additionally, how do I calibrate the VOLTAGE meter to read actual voltage out? I measure 14.64 volts @ output terminals. THANKS (again).

I am working from memory here. I think R104 can be trimmed to show the proper voltage on the voltmeter. Just like how R103 can show the proper current.

Potentiometer R5 will adjust the voltage output.

Here is a schematic of the supply;
