I changed the cristal quartz (4,43Mc) and the odd colors left finally place to more normal colors. I then grounded pin 2 of the 4,43Mc and then I tuned the reactance coil for steady color bars. The results were amazing especially thinking it is a tv more than forty years old! Ok, there are more things to fix, the focus control must be set fully counterclockwise to get a decent picture, there are few retrace lines on top of picture and the hue control must be set to its position were you normally get pink colors to achieve normal flesh tones.
Here are few pictures of the set...
I must admit I'm really happy!

I am happy too!
Is there a PAL delay? There is a hue control, i see.

There is a coil that will allow you to adjust the hue range. Set the hue control to mid position and adjust the coil for natural flesh tones. The location of the coil should be identified on the schematic. That's a great picture by the way. That's a lot like the way mine looks. I love the deep reds these sets produce.

Hi Gianni, the set has a tint control (useless with our Pal system) but no chroma delay line. Hello compucat, thank you for your advice! Do you remember what the coil you mention is? The flesh tone is achieved only with the control fully counterclockwise. Turning it even just slightly makes flesh tones go completely off (blue skin tones). I think I also need to replace few tubes here and there... You're right. The reds are deep,really amazing!

Interestingly, this set has no PVA cataracts...

I believe this set is fitted with simple PAL circuits. Simple PAL has no delay line but a tint (or hue) control.
