The part replacement for the flyback of my 1084s-P1 is HR 7533 after all (original AT2079-37591), just reserved one locally for 20€ . It seems that commodore used all sort of available parts at time and resulting in inumerous combinations for the 1084s series of monitors .

Time for update, flyback replaced, HOT replaced, monitor now as excelent image , sharp image and strong colors.

Now only remais some adjustements to the image, it shows kind of rotated to the left by 1' (last image), were can i adjust this??

Well, mine's fixed too! HR never wrote back to me about the flyback, so I ordered my replacement through Donberg in Ireland. They were very quick and helpful.

Some pictures:

The old flyback and the spare transistor.


Close up showing the model number on the flyback.


Make and model of the tube. PHILIPS M34EAQ01X


Flyback's 9 solder points


Flyback installed, alongside new horizontal output transistor, just right of the yellow rectangular thing, and clipped to the heatsink.


The picture is brighter and sharper than ever. Thanks for your help, AmiBayers!

JLPedro, the little plastic sliders around the neck of the tube adjust various aspects of the image, including rotation. They're very hard to move though, usually glued in place at the factory after calibration.

This is the correct replacement, yes?

Check which wires comes with the replacement flyback. Worst case scenario you'll have to solder the other end of the wire to the place it goes.

The little plastic cover should unclip and reveal the place where the wire joins on. If I recall correctly, it's a bit tricky to get off, but not impossible.

But yeah, that's all it is, there's nothing special about it other than the plastic cover.
