Radius Monochrome (Greyscale) Pivot Capacitor List
Posted by: warmech on 2026-01-21 00:10:54
So, I have disassembled a monochrome/greyscale Radius Pivot (model 0361 - apparently identical to models 0276 and 0425) in order to recap it. Deflection and geometry are perfectly stable, but the image itself is trash. The symptoms are almost identical to the ones experienced by my Apple Portrait Display from a few years ago when I acquired it from a warehouse in Houston. Its geometry was far less stable, though.

This, too, being a warehouse find, decades of exposure to uncontrolled heat/cold and humidity have almost certainly trashed the caps here as well (as was the case for the APD). The weather down here in the DFW area is supposed to be absolutely miserable this weekend (hello, freezing rain!), so I'm hoping to pick up a will call order form Mouser before then and will hopefully have a nice little recapping project in a few days... if the power stays on through the inch or so of freezing rain we're supposed to get.

I hope to make photos/video available as well, but the disassembly process is a real pain. If you need to work on one of these, I'd just say to shotgun all the caps in one go, lol.

Anyway, without further ado (dimensions are approximate):

Looks like I cannot edit the above post anymore, but there is a small update, as I finally sat down to recap this thing. There are a couple of errors/missing caps on the list above that I've since either corrected or added; for reference, they are as follows:
  • C109 was not 4.7uF - I misread. It is instead 47uF.
  • C326 is a bipolar capacitor - I had originally thought it was a polarized one (writing on one side looked like the anode band).
  • I somehow completely missed one on the PSU - CX517 is a 1uF 50V capacitor.
After an almost complete recap (missing the bipolar cap and CX517), this display is looking good as new. There are some extremely minor pincushion issues that are barely noticeable, but I think the last couple of caps and some burn-in time will correct this the rest of the way. This monitor went from entirely unusable to bright and crisp, so I'm very happy!
