Before I forgot, I undid the recent change I made to R14 of PDH box #1437. To refresh your memory, I changed this resistor from 25 ohms to 330 ohms to reduce the input stage gain of the box by about a factor of 10 (so that I could increase the optical gain). Unfortunately, this resulted in an exacerbation of the gain-dependent DC offset we noticed some time before. In any case, I am beginning to design our own proprietary gyro PDH boxes, so we will soon leave these aside for general purposes.

I couldn't find a 25-ohm resistor (or 2 50-ohm ones), so I used a 27-ohm one. I will update the schematic on the wiki.
