Is it possible to add an astigmatismus adjusting board in the PG machines??? Who can help, or is it nonsence??????

I think it must be easy to upgrade the PGÂ´s into PG plus or EXTRA,

if IÂ´m wrong, please help!

Does anyone has the service manual from the PG+ or extra, how does the astigm. adj. works on the three tubes??? Do we need also new deflection yokes??

Any ideas out in the blue?

All the best

Daniel
