SP 261B psu schematic

[Experimentonomen]

This question is mainly directed to Steve aka mixedgas but if anyone else have what im asking for, feel free to answer.

Im looking for the schematic for the sp 261B psu, mainly because i wanna figure out the light sensor in the 161B head, if its calibrated for 1mV/mW if hooked straight to a dmm or if the signal from it passes some transistor or opamp circuit on the way to the power measurement output in the remote control connector. I did put a dmm directly on the wires coming from the sensor and got 25mV with the laser running at 7.86Amps.

Note that i do not have one of these psu´s available to backtrace the sensor wiring, which is a shame

I don't have a 261, but what about a 262???

Bummer
I´ve had the schematic for the 262 for some time already but its no help for me as the remote control jack isent even drawn out

Oh well, i guess i´ll have to wait till i get an lpm after all then.

Thanks anyways.
