Summary

Interesting middle-era CRT somewhere between the 2530 and 2950Q generation of Sony chassis design. I say middle-era because it has a digital menu like the 2950Q but it doesn't have any digital geometry or convergence controls - those are still handled by internal potentiometers. It is also not as feature-rich as the 2950Q, in that it only supports the single NTSC color system instead of a world-wide compatibility.

The tube number is strikingly similar to the Sony KV-32S42, possibly just with a different yoke and/or darker tint color on the glass.

Notes

Corner convergence can be tuned using potentiometers on the "Convergence" board (see pictures).
