I'm sure the acoustics help a lot but our MOS-1 organ sounds pretty good, at least in my opinion, considering how old it is. Another church I visit once in a while has a newer Renaissance Allen from...

Well that was easy (thanks to the advice here) The outputs from the crossover where being sent to the wrong amps (bass was going to treble amp and treble was going to bass amp). The volume is back...

Jbird, I appreciate the detailed reply. You've been a big help to me in the past as well, the troubleshooting tests you once told me to do helped us discover a problem a year or two ago that was...

Let me ask this, the 2 amps that were replaced were the sw/gt/pd Flute Treble and sw/gt/pd Flute Bass. From what I can see, a single audio cable goes into a filter that separates the high and low...

Just to clarify, adding celete effect anywhere on the organ makes the problem worse, the swell and great are way to loud but their respective amps are set the same way they have always been.

The organ in my church is almost back to normal. About a month ago we had two amps replaced (Flute SwGtPd Treble and Flute SwGtPd Bass). The amps that were put in did not work so we had Allen back...

Thanks for the answers guys.

jbird, I'm not really sure what to do with my Rodgers at this point in time. Right now it still serves it purpose pretty well for practicing. Obviously the issues...

I came across this instrument when browsing on ebay. While I'm probably not in the market for a new organ now, within a year or so I think it will be time to give up on the Rodgers C-505 that is in...

So I get another phone call, the dealer fixed the problem. I have a suspicion this fiasco involves the Rectory and certain people in it who get involved with things they have no business in and not...

So our Allen dealer comes out, says there is nothing wrong, tells the rectory I don't know what I'm talking about, and leaves. Unbelievable.

Hi everyone,

After many months of no problems the old Allen in my church is acting up again. Prior to this some foam surrounds were replaced as well as some bad computer boards and the organ has...

The church it is in has nice acoustics despite the aisles and choir loft being carpeted. I can only imagine what it was like before they covered the aisles. Fortunately under the pews amd the Altar...

After a bunch of problems our 1981 Allen is working right again. I want to thank jbird for helping me so much with troubleshooting the problems as it made things much easier for the repair people....

Not to go off topic but just an interesting side note my organ is an Allen 903-3DKC. Would that mean it is basically the same organ?

John,

I will certainly keep in mind what you just said if we continue having problems after this next repair. I believe the first repair they tried was to remove the boards and clean all the...

A quick update.

The service man came out last week and replaced the MOS Board on one computer which seemed to solve the dead notes problem and the Keyboard Array on the other Sw/Gt/Pd Computer...

I spoke with the organ dealer today and explained the problems I am having with the instrument. They will be coming sometime this week, hopefully I will have some good news by the weekend! He was...

John,

I too was surprised to find the Great having trouble but not the Swell after reading what you had told me earlier in the week. I did take a quick look at the white wires running through the...

Hello John,

I had a chance to do the tests you told me about. I found out some interesting things.

Regarding the dead C and F#s on the Great:

When I got to the church all the notes were...

John, thank you so much for all the information you gave me, its appreciated VERY much. Here is my plan

Unfortunately I cannot get to the organ until Saturday, but I will then go through the...

Hi everyone,

We have been having an ongoing problem with the Allen Organ in my church. The issue seems to be every C and F# on the Great being barely audible. There are two batteries of speakers,...

Thanks for the information and the picture Michael, I appreciate it. Are there any connections on the MOS-1 I should look to clean to help clean up some of the scratchy sounds or am I asking too much...

Quick question, would an MOS-1 organ have the same pots you are talking about? If so, where inside the console would I be looking for them, or if anyone has a picture that would be great. The inside...

Thanks everyone, I was able to get a decent sound for Easter, but since then I have been able to spend a couple hours figuring out exactly what amp controls what. Apparently the labels next to the...

Ok, played around with the gain on the various amps this weekend. It's a little difficult because while all the amps were labeled as to what they controlled, some of the labels have fallen off and...
