Recently I purchased a Zone VI cold light head (8x10). Basically it works fine, however, every now and then only the green tube is working when the head is switched on. When I switch off the whole head and wait for a couple of minutes it works correctly for the whole session.

I wonder if there is anyone out there who is aware of such a problem and if you know about schematic diagrams to get this head fixed if the problem gets worse.

Thanks a lot

Andre

Thanks for the advice, Robert. Indeed, Calumet in Chicago still have some spare parts on stock. Right now, the cold light works fine. Its probably a matter of temperature. So I won't disassemble the head right now...
Is there anybody out there also using this head and if so have you ever noticed such a behavior?

Regards

Andre

My enlarger has been great, but I've had less than good luck getting even info from Calumet about parts. Hopefully this means they've returned to their former selves in service!
