Ilford Multigrade 600

I recently acquired a new enlarger with the Ilford Multigrade 600 system (head, power supply, controller, probe).

I have no manual, and I am looking for a manual and/or someone who is familiar with this system to help out - anybody out there? One specific question that I have is what bulb does this take? - I am pretty sure that the bulb that is in there is not the one that ought to be......

I think you already got an answer on the IfordPhoto forum, but in case you missed it, and for the attention of anyone else who needs it, Ilford have made PDFs of the manuals for the Multigrade 600 and 500 heads available at: http://www.ilfordphoto.com/products/page.asp?n=161

There are a few other manuals for what I assume are mostly (all?) obsolete Ilford products there too.

Cheers, Bob.
