The NJM2100 opamp is used with unity gain in the stock form, but it can be used with higher gain. Replacing the feedback R from 18k to 27k will increase the output signal voltage by about 50%. E.g. at 1 kHz there is an increase from 1.1V to 1.6V. The signal is still undistorted and there is no clipping. Cheers, Mick

You have to adjust the Laser at 11,4 mV for short connection cable and 24,4 mV for long connection cable. Turn on the PS, push the cover close switch, you have to messure while the laser moves up and down.
The original laserunit and the laserunit of the PS ONE have a short cablefor connection. The laserunit AAM,ACM,BAM have to be adjusted to 11,4 mV, the AAM and AEM to 24,4 mV
