Summary

Adorable Sony portable from the 70s. It's quite heavy due to its nearly all-metal chassis and multiple PCBs inside. Excellent picture quality and true 9" viewable area. Some models have "Quick Start" filament pre-heating that can be enabled by popping out the "Picture" adjustment knob on the bottom right corner. If you don't see a Quick Start logo on the bottom right, your model does not have Quick Start (see images below). The Quick Start models can be considered more risky to purchase because, if this feature was used, it can severely wear out the filament in the CRT by keeping it warm even when the CRT is not in use.

Notes

This does not use Sonys common 8" A20JKU10X picture tube. It is a true 9" tube which predates the newer 8" tube.

The capacitors on the deflection board are very likely to be leaking - they are cheap and subjected to a lot of heat. I had to replace all of mine - the main 33uF 160v actually started venting after I used to the TV for 5 minutes and the horizontal width started shrinking!
