Hello, I have an Ilford Multigrade system on a de vere 504, with an RH Designs analyser pro timer.
Earlier today I went to print and just as I turned on the focus the left hand bulb blew. I replaced the bulb with a new one, but now the left hand light in the head of the enlarger doesn't turn on at all! and I'm at a complete loss as to what to do.
I have tested the bulb in the right hand side, and it definitely works.
I have tried a separate power supply (500s, as I have a spare), and it is the same.
I've also tried the ilford timer instead of the analyser pro, and that too doesn't make any difference - basically only the magenta light (the right hand side) turns on. The left hand light which normally gives the yellow light, won't turn on at all.
I have no idea what the problem might be, or how to repair it, and am quite upset as I use the enlarger a lot.
does anyone know what the problem might be? any help or advice would be greatly appreciated!
