I have wondered the same.Me too, me too. Outside of voltage reduction, I'd be curious to study why an enlarger light source would need any kind of fancy circuitry in the first place.
So we could still do it, but we would need 120V for the fan, and a regulated power supply of 82V (probably DC) for the light.Thank you Matt for that answer. Being a radio man, I'd still like to get my hands on some of that paperwork. I've read these powers problem threads before and can't believe I couldn't come up with a fix when factory parts are no longer available.
The instruction manual for the 45S states:So we could still do it, but we would need 120V for the fan, and a regulated power supply of 82V (probably DC) for the light.
These are part of my strategic reserve.
Sorry, i am lost...probably because i have never used that lever.First of all. The white light switch has a "paper saver circuit" . If you focus with white light, (filters out of light path), the enlarger lamp will not light until you put the filters back in place. This is to prevent the user from exposing paper without filtration.

OKSorry, i am lost...probably because i have never used that lever.
How or when will the lamp activate (via that lever) with no filtration.?
Thank You
.....got it... Thank YouOK
Start.
1. Turn on power.
2. Hit the focus button on timer, this turns on the lamp .
3. Throw white light lever to pull filters out of light path, allows you to focus with bright un-filtered light .
4. Hit the focus button on timer to turn off lamp.
5. Forget that you have NOT returned the white light lever back to engage filters. This is what gets people. If after focusing with white light and you forget to return the lever to normal the enlarger lamp will NOT light when you hit expose on your timer.
6. Remember to return the lever to engage the filters, hit the expose button on the timer and the lamp lights instantly for the prescribed time then shuts off.
This is the invaluable Paper Saver Circuit. Imagine you are portrait photographer in 1985. You get ready to print 100 identical 5x7 prints, you know the exact filtration and time. You insert your negative in your negative carrier start to adjust composition and focus. Ah, if I flip the white light lever it will pull the filters out of the way. You adjust the focus and composition, reset the lens f stop to f 8. BUT FORGET TO RETURN THE LEVER TO ADD THE FILTERS BACK. When you hit expose nothing happens, and you realize, before you make 100 bad exposures, that you forgot to put the lever back in place.
This was a great feature, the orange mask and colors of color negative film required bright light for focusing. God forbid you were a humble printer and you screwed up a big batch of prints that took 2 hours to expose and 2 to process only to find out you forgot to "lower the landing gear before touchdown!"
That's it.
I did not realize Beseler was still in business.Trust me, if you don't use the colorhead for a couple weeks, or months you will find yourself scratching your head. I wish I had a jillion dollars, I would love to see and try Beseler's new cold LED Dichro L head. Full white LEDs with dichroic filters. Not RGB LED arrays.
Yep, that's it. It's a big box. The price has dropped considerably since it was first announced. I think the prime target customer is education, and we all know what's going on with the chaos of pandemic and remote teaching etc. I would really like to see a review of this, maybe Silvergrain Classics could get a look at one. My concern with something like this is long term support. I've got color heads that work. I'm mostly interested in a variable contrast constant exposure head. I can do this with my colorheads I have now, and an occasional color print for fun.I did not realize Beseler was still in business.
Are you talking about this head that fits a Beseler 45.?
Looks like it has an external power supply, or is that something else.?

Would it be possible to also get the service manual as well?Schematic for the power supply sent via e-mail.
Kelcey, did you end up getting the service manual? I am looking for some info on the output voltage at the bulb socketWould it be possible to also get the service manual as well?
thank you

Those little springs on the filters are difficult. These old ones are analog, no chips. You choose well to get rid of the circuit boards, very obsolete components.I have an old Dichro head from the USA. So, I had to throw out the fan, electrical plates, and use a halogen lamp for 24V who connected to the power supply 220v -> 24v. There isn't anything that you couldn't repair, except for small color glasses.
P.S. I have no manual
