Hi all,

I have located a Macbeth Tr 927, though the seller tells me that the light in the transmission part is not working. I'm sure this is a easily fixed with a replacement bulb? Where would I get one? Also the check plaque (black/white) is missing? I'm unsure what this is? It could be calibration plaque? Where do I get one of these? From what i've read these things do "Status T + Orthochromatic (ISOType 2) + Ultraviolet (ISO Type 1)" ? What exactly are these used for? The Ultraviolet I understand is if I'm using Pyro stained negatives, though unsure about the Ortho or Status T? There are other Macbeth's that do Visual and M? "M" is for masked negative, C41 orange based ones, is this correct? The Visual could also be the Orthochromatic channel? The Reflection part of the densitometer is working. Any help? Thanks Jacek

I have a pdf of the 900 series - download it directly from this link. (http://johnesimmons.com/Graflex/MacBethDensitometer/MacbethDensitometers.pdf)
There is a company in the US that repairs these machines and once quoted me about $25 for a bulb. I wonder if another bulb would work.

Also, when I opened mine, I found that there was a spare bulb under the cover. You might check yours.

Hi Juan,
I contacted Xrite who now handle MacBeth and they said they dont support this densitometer or have parts for it. Would you have a part number for the transmission bulb?
Thanks
Jacek

I'm sure this is a easily fixed with a replacement bulb? Where would I get one? With my 502 a replacement bulb was stored inside the densitometer, fixed to the lower lid. Maybe this good idea made it into the 927?
