  • Another chassis problem

    Does anybody know if you can take the diodes and resistors that are under the capacitors and spot relay out of the circuitry of the chassis? I had a sweep reverse switch short circuit the omega tech boards in a chassis. I replaced all other burned out parts in the chassis, including varasitor and diodes on the heat sink. I have checked the fuses and circuit breakers. I checked to see it the heat sink was grounding out. Found the capacitor was burned up and stopped there because I saw the resistors and diodes soldered into the circuitry. I was thinking with the omega tech boards in the chassis are those diodes and resistors necessary. I have 82-70 machines, SS chassis's/with both omega tech boards, and accuscore. Any ideas? Thanks.

    You are an overachiever. I can barely handle PCboards on my antiques. You are attempting to repair OmegaTek's! Woah!
    Best of luck, get out your microscope!

      AMF MAGIC, Let me clear this up. I don"t mean the resistors and diodes on the omega tech boards, I mean the diodes and resistors under the spot relay and capacitors of the ss chassis with omega tech boards instead of the traditional 5 board setup. Maybe I'm crazy or thinking too much. Knuckles [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img] [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img]

          Hey Magic, I think I'll join the club. I 'm going to call one of those repair/exchange services in the thread pindecked started "chassis repair/exchange." To many gremlins, not enough beer or advil. Knuckles [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img] [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img]

            I saw you didn't get even one real answer to your question, so I will give it a try, at home without any books or anything.....

            The purpose of the diodes, putted parallel on your relays( swsr/be/main-24VDC contacts #2 and #10) are simply there to give them a little longer live or/and let them sound a little bit better. If you want to live without those diodes...Buy some new relays but then between 24V and 50V AC, AC? YES AC!

            I think Bowlequip or 8270/king will have better answers but I give it a shot..

            Good luck

            So it goes.

              I Don't understand why you stopped at the 25 cent diodes and resistors and settled on spending $75+ on a rebuilt.

              Sounds like a commercial for a club I don't want to belong too.

                Bender, I was working on the chassis and checking the continuity of the resistor under the capacitor, sometimes it had continuity and the next second it did not. I know the resistor is bad but then I thought with the omega-tech board maybe the resistor was obselete and you could bypass it. I have several chassis available so its not a high priority. It was just something that crossed my mind. I called omega-tech and they said all that hardware is bypassed by the omega tech boards.
