Beseler 45a Manual
Currently there are 2 heads available for the beseler 45. The good old 45s which is just bulb and filter.
A short guide to and description of Beseler 45 series enlargers. Feb 20, 2017 - I just bought a 45A and need a manual. Does anyone know of a free site that I could download one? Thank you Brandon. Instruction manual for early Beseler/Minolta #8289 and #8290 45A Enlarger Light Source systems.
I believe Nick has this one. The Universal 45 has 3 bulbs and requires a controller to go with it. You can get either a VC or a color controller. I am not familiar with this head. I have what is called 'color computer head' which very much the same as the 45s but the filter values are measured by the sensors in the mixing chamber and displayed in digital form with LED. I like this one very much, as the filter values will change with bulb aging and very consistent. There was also the Minolta/Beseler 45A, which used repeating strobes with 4 flash bulbs.
I heard that this one is very troublesome. Beseler Dichro 45 color computer head and D.A.T.A. Module I have a Beseler Dichro 45 color computer head and a Beseler D.A.T.A. The color head works fine with a regular darkroom timer, but not with the D.A.T.A.
I found out that if you use the D.A.T.A. Module with the Dichro 45 color head you need to replace one of the integrated circuit modules (IC6) inside the head with a new pre-programmed piggyback IC6 module. Of course Beseler doesn't sell these anymore and no one has any laying around.
I also found out that the module is a Mostek 3870 and the manufacturer went out of business in 1985. Even if I could find the right part it would be useless because it's an EPROM that needs to be programmed first before it will communicate with the D.A.T.A. It's simple to program one of these if you have one you can copy from. If not you are pretty much dead in thewater and the D.A.T.A module is useless. Click to expand.Beseler 45 S is a simple and straightforward workhorse type colorhead. The 'Minolta-Beseler' and 'Computerized' colorheads are tricky to use and difficult and expensive to service. Many of the computerized heads are sold minus the absolutely essential D.A.T.A.
Module without which the colorhead is useless. The flashtubes for the Minolta-Beseler haven't been made in twenty years and they were made in Japan. Make sure the fan runs strong on all the colorheads as they often don't work properly. Keep in mind though that you don't need a colorhead to make color prints.You can always buy a set of color filters and use the built-in filter drawer on the condenser head. No I scrapped the idea of converting the Beseler 45 to anything larger. I have a Durst 138 5x7 enlarger.
For the Beseler enlarger I have a cold light head and I converted one of the Beseler heads to take a 120 Volt halogen bulb with the same specs as the 83 volt bulb that was dedicated to the circuit boards that long since failed. I am using the Beseler right now but will be changing it out with the Durst this Summer. The Durst can be turned into an 8x10 enlarger with a head extension with a slot for a negative carrier and an Aristo cold light on top. Several people here have done just that. Beseler made or makes a conversion to 8x10 but it is or was very expensive, I am not sure about a 5x7 conversion. There are several models too, I have the model with a larger bottom lens stage that has a square mounting plate that the lens board goes on.
Some models have a small tapered bellows to the lens stage. Aristo had a Beseler 5x7 head listed but I believe it was for the CB model. Beseler 45 enlarger dichro color head Wow!
It was years ago you guys were last discussing these units. I received one of these today as I need to modify to 5x7 right away. Anyway, the bulb in the Dicro45 color head appears burnt. How do you remove it?
I have the unit open and removed the main large cylindrical lamphouse (condenser?). But the bulb appears to be in a small black metal box on the right side. No idea how to go further. Help would be appreciated. I have a bushel basket of new 7 inch long negatives to print.
Thanks for any help--oh yes, I will probably eventually have to abandon the dicro45 unit anyway and replace with a homemade or Aristo 5x7 lamphouse. But I would like to see this unit working. I hate having things laying around that are broken. Besides I could print up to 4x5 with it. I've got a 45 Dichro Computer head on a 45V-XL with two working MODULE contollers, one new and one used, and an extra chip needed to use the controller. Caldo Sangue Scarlatti Pdf Printer. I had to replace the 3 gain dials on the head with something more industrial. The gain dials that zero out the display are very fragile and if you ever have to remove the circuit board chances are you will pop one of them off.
