Rodgers 960

[edwardp001]

Hello everyone,

Im trying to find a schematic diagram for Rodgers 960 organ. Having problem with power shutting down while playing. It all began with shutting down once in a blue moon then weeks, days and now it's down to 10 minutes. All lights stays on but keys, stops and pedals shuts down, no output at all.
Any assistance will be greatly appreciated. Thank you.

This is the wrong section of the forum, the 960 being a Classical/Church organ. Post in the Schematics Wanted Section if you just want the schematic; post in the Classical forum if you want help (but don't ask for the schematic there). I'd advise, but I do not know anything about the Rodgers digital organs.

TBH, Rodgers never really published any specific service manuals for the larger digital organs such as the 960. For the most part, each organ would be built up from a prescribed set of components, and most drawings and schematics for individual boards and assemblies are available to their authorized techs these days on their tech website. It's possible that Rodgers would sell you a full set of those for your organ, but I can't say.

If I were servicing an organ of that type with that symptom, I would start by breaking it down, removing all the socketed boards from the cage (very carefully, one at a time, labeling and marking and making sure to get them back in correctly!). This type of problem is very spooky, and may well be caused by nothing more than an electrical discontinuity at some point where current or data is passing from a board into a socket, or through a ribbon cable or other connector.

In fact, a few years ago we had a 968 ("Masterpiece" model with about the same spec as your 960) that was doing more or less the same thing. In that case, we finally discovered that one of the DVM boards (tone generator boards in the cage) was the culprit, as the organ would operate normally with that board pulled (though the stops it created were of course silent), and fail again when it was reinserted. WHEN PULLING OR INSERTING BOARDS THE ORGAN MUST BE POWERED OFF!!!

But lots of other such troubles have not led to a specific bad board, but have cleared up once the organ was given a very thorough maintenance -- pulling, cleaning, lubricating, firmly re-seating every board, every socketed chip on every board, every cable and connector. It takes a lot of time and patience, and you might be better off to call in a good tech. But that may well be all it needs.

Thanks for your response. It's helpful to have the insight of someone who have encountered a similar problem that we're having. Next week, a tech from Rodgers is coming. At least we are more informed to make suggestions of what may need to be done. I am not aware of the schematic diagram section since this is only my second post in this forum, thanks for the info. and please accept my apology.
