G05-805 Tube swap.
From a friends cocktail cab.
The monitor came to me slightly faulty, the Contrast adjuster on the deflection PCB was totally out of spec. and was replaced. Also the Focus adjuster on the HV PCB was bad causing brightness issues on the monitor, this was simply 'worked' back and forth a few times and the issue cleared. The HV and deflection PCB's had previously been repaired and now was all good.
I also the chance to swap the tube over for a NOS one that was sold on the UKVac forums a few years back.
Needless to say the new tube gives a great image and only takes around five seconds from cold to show an image. Here's a few photos of the process. Yoke swap was interesting to see how moving it around altered the screen image.
