Other CRT chassis & equivalence table

The arcade chassis landscape is vast. This page gathers the other makers (Toei, Neotec, Rodotron/Pentranic, universal Wei-Ya…) and above all the equivalence table: which chassis can replace a dead one. Repair is always the same family of steps → CRT safety + Recap.

Makers & common chassis

Maker Chassis (e.g.) Region / use
Toei TC-RM251S (25"), CM-F20U, CM-14 JP — a major, alongside Nanao/Sanwa
Neotec NT-2700 series / NT-2702 (≈ Nanao MS8/MS9) replacement chassis
Rodotron / Pentranic CH-688A, Rodotron 666a / 666b1 replacement chassis (EU/AU)
Wei-Ya (universal) C825H-2 / C825HR-2 / 825H1, 2929 / 2931a universal replacement chassis (modern tri-sync)
Makvision / Kortek M3129, 3125B… modern tri-sync → dedicated page
Others seen Orion, Glendale, Philips, Hitachi, Vision Pro, Betson… per cabinet/region

Equivalence table (chassis swap)

A beyond-repair chassis can be replaced by an equivalent — check tube, yoke (deflection) and frequencies before fitting. Per Arcade Otaku & vendors:

Group (interchangeable verify) Frequencies
Nanao MS8 / MS9 · Sanwa PM-1745 · Rodotron 666a · Wei-Ya 2931a · Neotec 2702 15/24 kHz, 29"
Nanao MS2932 · Rodotron 666b1 tri-sync (untested against MS2930/MS2931)
Sanwa 29E31S · Wei-Ya 2929 / 2931a tri-sync 29"
Sanwa PM-1723 B/C/D · Sega 200-5090 / 20V21S 15 (/24) kHz, ~20"

'Equivalent' ≠ plug-and-play

Same electrical family ≠ same connector / yoke / adjustments. Expect to rewire the input (RGB/sync), adapt the yoke if needed and set geometry/focus. A universal Wei-Ya chassis is often the simplest route for an "orphan" tube.

Repair (common method)

All of these repair the same way:

  1. HV discharge → CRT safety.
  2. Recap → method; read the BOM off the board (revisions), the big filter often outside the kit.
  3. Reflow (neck, flyback, connectors); HOT / flyback = wear.
  4. Adjust focus / screen (G2) / geometry.

Review & corrections

How this space is used

Spotted a wrong value, an outdated procedure, a chip reference that does not match your board? Say so here, with what you observed (model, board revision, serial number, measurement). Every report is cross-checked against a source before anything changes — an unverifiable correction is published as “reported by …, not cross-checked” rather than silently applied.

Reading is open to everyone; posting requires signing in with Discord. Reports from the wiki's declared reviewers are handled first; anyone else's are read too, but go through a human before anything is changed.
