A new home for my UV solder masks: 15 ml amber glass jars with airtight plastic lids.
From the beginning, there were problems with the syringes, which often dried out or leaked from the top. Although the masks have now expired, they still cure and are too good to throw away.

1. Back of the linear PSU board.
2-4. The switching PSU is a Sanken SSG030-05A, whose LED flickers irregularly when switched on.
For now, I am only providing photos of the inside (three different screws hold it together) and will begin analysis/repair at a later date.

First impressions of the Pioneer CD-I AUTOCHANGER COMMANDER COI-V10:
CD-i PCB, A/V PCB, I/O PCB, a switching PSU and a linear PSU (transformer, power PCB, power switch PCB). Of course, these are not all of the PCBs; there must be at least three more at the front of the unit.

Pioneer COI-V10 โ two power supplies.
The fuse holders on the linear PSU board were a bit loose and brittle, so I had to replace them. I also cleaned it with ColorCoral โ you can really see how dirty it was from the before and after colours.

I finally upgraded some discs from my PC-FX full set: Super PC Engine Fan Deluxe Vol. 1 & 2 (the last photo shows what I had before, just the discs and inserts that someone else had cut out of the mooks)
@leonkiriliuk Are you satisfied with the DFO output? I noticed that the frequencies on my DFOs were about 1.1 kHz lower than programmed, which caused issues on some TVs. However, since you are combining it with CD-i RGB, you probably won't notice this.
Random stuff from Japan (last parcel for this year):

Hudson Soft Super Joy Card (HC-691)
IBM USB Portable Diskette Drive (06P5222)
@CabriDIY Replaced the laser sledge and cleaned and greased the CDM. The focus error is now gone and the discs are reading perfectly again. As a finishing touch, I added a drop of UV lacquer to the spindle.
Reworked the Timekeeper with the PCB by @CabriDIY and thoroughly cleaned and greased the tray loader. The CDM has not been touched yet, but appears to be defective. The repair is a story for another day...
