Beseler Dual Dichro S 23 schematic

[Roscoe]

I'm looking for a schematic of the PC board for a Beseler Dual Dichro S 23 color head. I've had no luck at Beseler so far. I've also contacted off list participants of the "Beseler lamp delay for printing" thread who received schematics to see if I could get a copy but with no response.

The electronics people I've talked to say they might not be able to fix my lamp delay problem without the schematic. If you have one, I would appreciate a copy.

Thanks!

I did get the scematic back then and wanted to make a copy of it but instead I gave it to the lady that had the problem. She said that the part her guy recomended worked but I don't remember the part number although it was mentioned in the thread I think. I may also have some of the e-mails from back then on my old 486 computer.

I did send you the partical scematic, but I guess it's not enough for you to redesign a retrofit into the system.

I'll dig around some more and maybe I can get one for ya, I may still have the ladiy's e-mail address too adn try contacting her again.

This is one of the e-mails I got from Vera with a part number... Allied Electronics (800-433-5700) was PerkinElmer # VTL5C3

Okay, spoke to my guy. He did not have to make any modifications. When he first installed it without the schematics he had the leads reversed. This he then corrected. No problems.

Good news... Vera has sent me an e-mail saying she has the scematics and the information form when her enlarger was giving problems. I asked her to mail them to me so I can maybe get it scaned and posted as a PDF somewhere.

BTW her enlarger is still working fine with the part she had her electronics guy install.

Many thanks to paul ron for his diligence and kindness in tracking down this schematic. I'll post notes on "the fix" when it happens.
