Zone VI Compensating Enlarging Timer instructions

[Bill Burk]

True this is an old post... But there is a renewed interest in the instructions... So it's a good time to bring this thread up.

Hello Luther and Bill
Thanks so much for posting these instructions.
We have the round shaped light box with the tubes; my husband is just now making a mask as a secure seat to set the cold light head on.
The Beseler CB7 enlarger came with one Zone VI Stabilizer with "lamp intensity (settings A - L...)" and "exposure reduction-drydown (0 - 15%)" knobs as well as two timers both labeled "Beseler P-104 Timer" - one looks like it will work like a timer, the other has a gauge with 1 - 150 volts. Both timers sit side by side on their own "plugs" in the Beseler cart.

Thanks again, Bill, for forwarding our request to Luther. For the next few days we'll be testing as per the instructions and using some step wedges too.

bluejeh,

As soon as I can obtain another compensating timer, I intend to run some paper test also. It sounds like you have a variable contrast light head with a controller box and a compensating enlarger timer or just a Beseler timer. Does your light head have the blue and green tubes. If so, I am interested in learning how to run step wedges using a variable contrast light head.

Regards,

Luther

Luther, Bluejeh: For your paper tests, you might find the following chart useful:http://www.bnimages.com/files/zonevicontrast.pdf

Also, the instructions which have been scanned and posted are for the ZoneVI variable contrast head, not the compensating enlarging timer. I transcribed the set-up instructions from the timer instructions in the thread that Luther started; hopefully in the next few days I will get around to scanning the actual 2-page instructions and post them.

Luther, We have the Beseler timer made for the CB7 enlarger. Our cold light head tubes appear white.

We took the head apart to look at the light, its an Aristo DS2 HI marked on the outside of its canister, and is still on the Aristo website. It has white tubes, not green/blue, not turquoise.

Would it be a variable contrast head?
