Toshiba D29C456 "SB" Monitor Info?

[Shinsengumi]

I picked up a few NOS Toshiba D29C456 "SB" monitors from Zax and was wondering if anyone had details around these?

Supposedly these are tri-syncs and the first box I opened does indeed have a PE0493 chassis.

From Zax listing;
*BRAND NEW IN BOX* Namco: (598-365)
29" FLAT CRT Trisync (15/24/31Khz) Monitor (D29C456)

Direct replacement for Japanese Maximum Tune 1, 2, and 3 cabinets.
Suitable with Japanese Mario Kart Cabinets.
Suitable for use with most TOSHIBA based CRT chassis architecture.

Have folks seen these before??? Any more info that can be shared? And what's with the "SB"?

Here's a quick pic

I have worked on a couple of these before. Was installed in Mario Kart GP 2.
PE0493 is a tri-sync chassis. Arcade otaku wiki has some info on it, but it’s basically the same chassis as the PD1843 used in a lot of Sega New Net Citys. The PE0493 has the geometry pots on the chassis, but you can use the same remote as the PD1843 to get to the extended menus.

Is it a Toshiba tube or Matsushita tube? In my experience the Toshiba tube is brither with a sharper image.
Regardless.. Congrats on NOS tubes! Epic stuff!

Thanks BuddyC!

It's a Matsushita tube. Bummer it's not a Tosh tube, but still stoked to have a few NOS monitors! Curious how this tube/chassis stacks up to the Sanwa PFX...

Frame marked "SB" as well... What does it mean!?!?!?

In my opinion this tube-combo is miles better than the Sanwa PFX.
Congrats again with an awesome score!

Thx again BuddyC!

I emailed Zax about the "SB" on the box and frame. Not sure why I did not think of that earlier!
