MS2933 to HITACHI A68KSA30X

[kal20]

I have a HITACHI A68KSA30X tube that I would like to put in a Blast City with MS2933 chassis.

Does anyone know if that tube is compatible with that chassis?

Thank you very much in advance.

Tube is, yoke isn't.

The curvature will be wrong, so it won't fit the bezel.

A68KSA30X tube has different curvature than A68KSM696X?

A68KMS696X has the same curvature as A68KJU96X?

OK, I take back what I just said.

The curvature is actually perfect. It's absolutely bang on. The front of the tube bubbles up way more, but it doesn't matter, since the sides are exactly the same. The only problem is the mounting depth. The front of the tube extrudes further from the dog ears, so you'll have to backmount the tube on the frame. You'll have to add spacers in too.

Nice find! I had no idea!

Here's the A68KSA30X with a NOA-1502-02 bezel (same curvature as the one in the Blast City):

Here's the A68KSA30X (left) next to a Sanwa 29e31s (right) (again, same curvature as the MS2930/31/33 in the Blast).
