Philips/Mag 9P6040c101 chassis PTV843 int size change H & VNo data found in
the archives, tips, nor download area.  This one comes on
and when cold the B+ is about 90v, then after warm-up it goes up.
Curiously, the focus is better when it is low and the pix shrunk.  Need some
infor on this one regarding the power supply (what should B+ be) and how to
touch up the convergence.

I can adjust the b+ but it never goes above 110v.  I suspect a problem in
the regulator control circuit, but would like to get a look at the schematic
b/f getting into it very far.

Anyone have a manual on it?

Thanks.
