Hi to all,
Exciting stuff!
First internal/external photos ever of a 1967 Sony Chromatron color TV.
17 photos so far. Seems to be an all-tube chassis.
The Sony 19C-100 belonging to the Japan Radio Museum has been entrusted to Japanese friend N. Tezuka to make it work again.
Follow the endeavour by reading his blog:

Please keep in mind that Google's Japanese to English translation is, well "creative".
Later day update from info received from Japan:
CRT diagonal is 480mm/19"
CRT type is 480AB22
2x EHT rectifiers used: 1 for HV and another 1 for MV* (6.3KV) and FV* (4.1KV).
Also thinks it's a 3 gun tube, therefore not a true Chromatron.
*MV: Medium High Voltage
*FV: Focus Voltage
The Sony Museum Chromatron TV is a 19C-70 and this one is a 19C-100, therefore a new unidentified model with a smaller screen.
