Got this wobble on screen as well as not being able to vertically shift the image up or down.
any ideas? ta.

Voltage regulation issue i'd say. As said in the other thread, check the B+, should be 126v

Its sitting at a stable 128v

Is it adjustable though via the big pot at RV12?

Ive read that the standard non e version is 126v but the e version (mine) should be 115v. what do you reckon??

The MTC900/E USA version is 115v. All standard MTC900/E UK/Europe versions are 126v. The MTC900 was the previous chassis to the /E, it looks similar but is a bit different in design, thought it used the same voltages for B+, so 126v for the UK/Europe version. You can tell the USA version as it doesn't use the green connectors for power and rgb, it uses the white/clear mate-n-lok/molex type ones like you see on a WG chassis. Also, the USA version doesn't use two separate voltages, it uses one voltage for both deflection and degauss.
