This box contains one HBB15-1.5A power supply. I recapped the supply (replaced all the electrolytic capacitors), as I had done for the MOTM cabinets. The caps on the MOTM-900 were also replaced. I implemented my new protocol of grounding the two sense inputs and connecting zero volts (i.e. ground) rail to the AC earth. The outputs were re-trimmed to be close to plus and minus fifteen volts.

After installing the refurbished power supply, I checked every module in the Quantisise, both red and blue panels. Then I made a silly little patch, between it and the DIY Quantussy.
