I have made the modifications which appear to be all that differs between my model and the model found here:

However, both low and high resolutions seem to be twice as wide as the should be and therefore double up. The vertical size seems fine though.

I'm going to investigate a bit more but without seeing that exact models board and the values of the caps on that model, I don't know that I can complete this project. I'll go over again though to try and rule out any mistakes.

No worries and congrats!

My other M1438s (which is now my only one, since I gave the purplish one to a friend, since I couldn't keep it - too many CRTs!) is a slightly previous model, which might be the one you have got.

I will do a tube swap between the two 1438s in the next 2-3 weeks to see if the purple issue is a tube issue. I will sneak some PCB pics in and see if those help you.

Please let me know which part of the PCB you exactly need and I will do my best
