Schober Organ Notes No. 89

Disclaimer: We accept no responsibility for any unfavorable consequences resulting from following our advice


I hope you all had great holidays and are ready for Spring. I hoped that this issue would be back on schedule, but unfortunately things did not work out as they were supposed to; I understand now that is to be expected when you deal with contractors. Anyway, the job took twice as long as it was supposed to and when it was finished several feet of snow had fallen and partially melted. A lot of things I had removed from the house were covered with tarpaulins and were under considerable amounts of snow, many frozen to the ground. I was so fed up and tired I thought I would leave everything as it was until spring; I had no more strength. Fortunately a friend came and helped me uncover and move things into the shelter of the house. Somehow moisture and powdery snow had gotten through the tarpaulins and plastic coverings and would have wreaked havoc if things had been left outside any longer. AK

When Fred Henn started our group, he published this newsletter as plain typed pages. Our member, Bill Kohrumel, offered to format and add graphics, etc., to these pages. He did this work for years for Fred and when I took over as editor/publisher he continued his fine work for quite a while. Unfortunately Bill could not continue for personal reasons and had to give up his duties a few months ago. Right now Bill has health problems. In his communication with me he mentioned how glad he is to get e-mail from friends. I know that he considers everyone in our group as a friend, so if you wish to communicate with Bill his e-mail address is: AK


This issue will be sort of a problem solver issue. If you can help, please contact the member in need or me.


Instructions, schematic, ANYTHING on the Reverbatape model RV2. This must be the original transistor model. It has several more transistors than the usual RV3 or RV3A. In all the papers that I have accumulated for our library, anything on this model has eluded me. Now I have been asked for the schematic, etc. Please let me know if you have anything at all. I will gladly pay postage and copying charges. AK

Dear Alex, Would you be so kind as to give me a lead to some info about how to trouble-shoot my Schober Recital organ which has two problems that have bothered me for some time now.

1a) With all stops off, the pedal board plays at about 1/2 volume;

1b) With all stops off, the swell keyboard plays at about 1/8 volume; (With all stops off, the great keyboard doesn't have this problem to any audible extent)

2a) On both keyboards, the middle D key also plays the D below it when any 8' stops are on; (except for the 8' trumpet on the great!)

2b) On both keyboards, the D key below middle D also plays the D below when any 4' stops are on. (The pedal board doesn't have this problem.)

These phenomena weren't present after I built the organ in the mid 70's, but appeared in the last 5 years. This really has me stumped, and anything you could do to help would be greatly appreciated. Thank you. Peter Soby:

Dear Alexander: I am sending this for my father-in-law. With respect to a 1972 Schober Theatre Organ: I am testing the TTG 4A/ 1120B tone generators prior to tuning. I have replaced resistors 71 and 72. I have replaced capacitors 7P I have checked transistors 7E, 7K, 7R. They are good (NPN) All outputs from 1 to 6 are very good on all boards. As to output 1: C - C# - D are there, but not quite as strong as 1?6 from D to B, the output gets weaker and noisier. Any Suggestions? Or a Tech Note? Thank You. Mr. Hill / Larry Bruen at:

Parts from a Recital Schober

Our member Charles Witherell writes: Schober Recital components recently removed to install digital circuitry, available free to an orphan in need. Everything from a fully operational Recital model, except console cabinetry and speakers, keyboards and pedal clavier (and their contact boards). Includes a Reverbatape unit, a Schober tuner, TR?2 amplifier, complete combination action and associated console installation hardware. Too awkward and bulky to pack and ship--should be picked up in Monterey, CA. Contact:

Interviewer: Can you explain jazz?

Yogi: I can't, but I will. Ninety percent of all jazz is half improvisation. The other half is the part people play while others are playing something they never played with anyone who played that part. If you play the right part, it might be right if you play it wrong enough. But if you play it too right, it's wrong.

Interviewer: I don't understand.

Yogi: Anyone who understands jazz knows that you can't understand it. It's too complicated. That's what's so simple about it.

Interviewer: Do you understand it?

Yogi: No. That's why I can explain it. If I understood it, I wouldn't know anything about it.

Interviewer: Are there any great jazz players alive today?

Yogi: No. All the great jazz players alive today are dead. Except for the ones that are still alive. But so many of them are dead, that the ones that are still alive are dying to be like the ones that are dead. Some would kill for it.

Interviewer: What is syncopation?

Yogi: That's when the note that you should hear now, happens either before or after you hear it. In jazz, you don't hear notes when they happen because that would be some other type of music. Other types of music can be jazz, but only if they're the same as something different from those other kinds.

Interviewer: Now I really don't understand.

Yogi: I haven't taught you enough for you to not understand jazz that well.
