Does anyone know if the  sensor arm Photo resistor is still available, and if so where can they be obtained, a leg has broken off mine and I need to replace it, failing this does anyone know  the specification of the photo resistor (OPH1) so I can try and find a suitable find a replacement

Alain ("boneofiel") on the Beolover Blog used an OSRAM LPT 80A with success as well.

Great, thanks, the manual shows it as an LDR as opposed to a photo diode but these are relatively cheap so certainly worth giving a go

Alain's blog post gives a detailed look at the original circuit and his replacement. It's good information whether you use his solution or not.
