    • Yoke and tube specs for monitors

      Let's start one of these as there seems to be interest in one. Hopefully everyone will contribute so we'll get a comprehensive list at some point.

      For measuring the yoke, the tool that I use is the BSIDE ESR02 PRO. It seems accurate enough.

      BSIDE ESR02 PRO- cheap tool recommendation

      It's a really nice for this job, because it shows both resistance and inductance at the same time and keeps the values on the screen fixed for 15 seconds, which is enough time to jot them down or to snap a pic.

      You can pick one up for around 20 USD. Remember to get meter leads for it.

      Some specs can already be found here:

      However, I would like to see additional info added to these.

      ---

      The list will follow this format:

      Monitor name (usually on a sticker on the frame somewhere)
      Tube brand and model (sticker on the tube)
      CRT base / neck connector (see here)
      Chassis model (found on the PCB somewhere)

      So I have three "100% working" Toshiba PF's (PD1843's) coming from yaton. Will test them on NNC's that already have Toshiba PF's when they get here to validate "100% working" status. Then will install them on my Sanwa PFX-based NNC's to confirm compatibility. If I would have known this sooner, would not have spent any effort trying to assemble Martin Jones's Sync Pulse generator.

      Also have one of those meters on the way.
