So I finally had the time to really test my second Astro City cab, this time with a Nanao MS8 instead of a MS9. The tube is absolutely brilliant with no burn at all, but unfortunately the picture is kind of wobbling, really hard to get it stable with the HOLD poti of the remote board. Just now I was experimenting a little bit more with this and received a vertical collapse...
Switched it out immediately, after that it was working, but still wobbling. Further observations: the CRT has also a relatively high frequent feeping when turned on and the V. ADJ of the PSU isn't working.
Is my chassis dying? Is it the voltage? Should I open a claim with the seller? What can I do?
