I've had this Zone VI cold light head laying around for years unused. It came with my Beseler 45MX enlarger, but the way it was just set down through the top of the enlarger head to rest upon the negative carriers looked haphazard and rigged-up. Some sort of wool band was stuffed around the outer edge to in an attempt to block light spill; all in all, it did not inspire confidence.
When I eventually brought the 45MX into service to complement my 23C, I remove the CL head and found a condenser head to print with. Not bad but contrast is an issue and I tend to find myself printing with grade 1 to 00 VC filters to compensate.
In addition, I recently started reading all of the Zone VI newsletters in which Picker relentlessly attacks condenser head enlargers as being impossible to use for "real" printing (as well as RC paper, but we will leave that alone for now).
This got me to wondering if I should try to revive this head.
Looks like it is the earlier head, as (if I read right during research) it appears to produce "white" light and not the "aquamarine blue" light of the 2nd generation heads Zone VI produced.
Also, while the lamp works, I am noticing some phosphor delamination on the tube which cannot be good.
As I also understand, I would also need to purchase a used Zone VI stabilizer, which runs about $100 on Ebay to have good, repeatable results. The enlarger was bought second-hand and the stabilizer was either lost/separated from the enlarger, or never used in the first place.
I am concerned that after buying a stabilizer that either the head or stabilizer will not be long lived enough to make it worthwhile and that the slap-dash mounting setup will result in varying exposures despite the addition of a stabilizer.
Posts I have seen also seem to imply that the white-light version of the head is not very useful for printing VC papers anyway...
A modern LED lamp house would be nice, but is beyond my means at the time.
Opinions on if I should resurrect this beast or if I should continue fine tuning my exposure and development times on my film to try to bring the negative contrast down to print in the middle range with a condenser head?
After reading so much about it, I would hate to miss out on the experience, but would also hate to spend a lot of time and energy re-aligning my processes to be let down by equipment failure or lack of flexibility in the future.
You don't need a stabilizer. Just plug in the heater side of the head 30 mins or so before your start print. I check light output on the easel with a Luna Pro with an enlarging adapter (the same ones every time for consistency), and at each height/lens combo I normally use, and these show no drift of any significance over time.
You may need a corrective filter to print with VC, I don't know because I don't use that head (I have the VC head from Zone VI which is really nice). That may be necessary to get normal VC filtration to work.
Zone VI compensating timer is an integrator but you have to use its timer.
The Zone VI stabilizer actively changes voltage to hold a stable intensity so you can use any timer.
Zone VI Metronome is simpler and beeps every compensated second.
All three would work with that lamphouse.
As for the life of the bulb, you can get replacements for it. I have a spare.
For evenness, it should be a little above the diffuser. Mine actually fell down once (the clip in the middle of mine was just a twist of wire that came undone). It looked pretty ugly with the grid obviously showing
@Bill Burk are you aware of a source of replacement bulbs for the Z VI VC heads?

Once I started printing with a cold light, I never went back to condenser. The comment by poster above about them "not being good when they worked", is ridiculous. I have an Aristo VCL4500 for almost 30 years, and a 1212.
