Oil boiler control box - please advise?

[Burnerman]

My ancient Panda 55 boiler, with an Inter 10 burner, uses a Danfoss BHO11.1 control box which I appreciate is long obsolete.
I gather that a suitable replacement is an OBC82.10 control box, but someone told me that it too, is obsolete.
Would there be any problems replacing the thing with a Satronic TF832 which needs a MZ770 photocell - or better still, using an 832 with a Danfoss LDS cell?
I'd really appreciate any comments or indeed alternatives!
Many thanks
John

Bump!
Maybe the TF830 with a MZ40 may be more up to date.

Either of those will do and will be the cheapest option. You will need to modify the wiring slightly as the BHO had a permanent live with the thermostat switching a loop.

Many thanks indeed for your reply!
I have 3 BHO's with me - one that has a blown capacitor inside, pending repair; one that has a spasmodic fault that I can't identify and one that is holding up for now.
I've a spare burner too so I can faff with that at my leisure to test my modified system.
Cheers again

The spasmodic fault will probably the failure of a holding coil under heat, like pump solenoid coils. As a boiler technician, it never made sense to delve too far into a BHO failure as replacement with a current set-up was quick, comparatively cheap, and more to the point, reliable.

Sound advice, ta!

Must agree re spending to much time on old burners.
We go one step further as we change better than 2 oil boilers a week always have a decent rdb burner about swap and away.

Due to the width of the Panda (300mm) means that the Inter 10 has to stay. A B9A would go in, but I’d have to modify the door.
Happily all parts are available including the drive spline which is a weak spot.
