Ilford 500 Bulb Blowing Blues

Moving the enlarger head while the light is on is not good practice, but 6 bulbs this sounds like a wiring socket problem.

Hello Bob,

So, I went ahead and ordered two new sockets for the lamp assembly, thanks Luis. I'm not quite sure what you mean by a wiring socket problem. Could you explain?

I also ordered some Made in Japans Wiko bulbs.

If they are Quartz halogen bulbs make sure you don't touch them with bare fingers. The oils from from your skin make bad things happen.

the sockets burning out and not allowing a good connection when the bulbs are inserted. But I think you are addressing this problem , oil on fingers as pointed out is also a big problem.

And the right voltage bulbs.

Take a look at the Ilford Manuals http://www.ilfordphoto.com/products/page.asp?n=161
First version 400W power supply with head that use ESD 150W lamps http://www.ilfordphoto.com/Webfiles/...1151751747.pdf
Newer version 600W power supply with head that use ELH 300W http://www.ilfordphoto.com/Webfiles/201172015792221.pdf Look at p.44 for frequently blown bulb or lamp contact black or pitted.
As said earlier, don't move head when lamps are hot. Don't touch lamp inside surface and manipulate them without glove and as Bill said make sure lamps are blown and not only the Ilford 500 system protection mechanism that stop them to lighting when they are too hot.

I am curious is anyone has experience changing out the halogen chassis, or knows of someone who has posted detailed instructions, or even a video of how best to go about opening up the unit, and swapping out the chassis, including if it is best to try and rewire at the chassi, or open up the top of the unit and run the new chassi cable up to the top and re-heat shrink it in there. Many Thanks.
