Schober Organ Notes No. 50
FROM THE EDITOR
ALEX KRUEDENER is "on the lookout" for new members (outside of the states).
I've asked Alex to "handle the whole operation" himself (I'm not looking
for any added duties (my TIME is in short supply now). Additional American
members and additional items for Organ Notes; YES ... but additional duties;
YES! ... I'll remind you when your Organ Notes donation runs out. HOWEVER
... I'm now asking for SASE's and loose stamps as your donation.
6 SASE's plus 4 stamps will bring you 6 issues (1 year's worth) of our
newsletter. As far as I know, the Postal Service doesn't have any objections
if you use "return address labels" instead of having to "hand write" your
name and address on the SASE's.
BILL KOHRUMEL has kindly agreed, in addition to keeping our EMAIL LIST
current, to make the list available to our group. When I inquired about
how he intended to handle the procedure, Bill replied (in part); "if someone
wants a copy, they must have email facilities or they wouldn't want the
list. Why don't you just put my email address in the article, and let it
go at that?"
SO, if you're interested in the list, here's Bill's email address: firstname.lastname@example.org
LDR SPECIAL INFO
ALEX KRUEDENER writes; "Well I think I have some good news. Using a special
light meter and various other instruments, I think I have found a combination
bulb/photoresistor that acts the same as the Schober version. Also from
the only soft non-functioning Schober LDR that I have opened up, it seems
to me that the photoresistor is the problem. The bulb is rated at a much
higher voltage than what it operates on and does not burn out, consequently
the soft LDR's can be fixed. It has to be done with instruments as the
distance between the bulb and the new photoresistor is critical. I also
had a hard non functioning LDR and the bulb tested good, but when I opened
it up I wrecked the whole thing. The next one I open (if I get some more
bad ones) I will know what to do.
Another interesting thing is that the soft and hard versions of the
Schober LDR's show somewhat different resistance values, but since they
have the same Schober number I assume they are interchangeable. Anyway,
I will soon test two of my totally new homemade versions in the vibrato
section of my Consolette. If they work I will be just delighted. Then I
will ask someone who has a circuit using LDR's for volume control to test
one out for me. None of the boards that I have are the newer "A" boards
that use LDR's for volume control. So I guess that is it. If things go
as I hope, I will write up how to fix an old LDR, how to make new ones
and the specs and where I got the parts. Hope I am not being premature,
the test will prove it all."
SO ... ALEX NEEDS A FEW BAD LDR's FOR EXPERIMENTAL PURPOSES. If you
can help ... here's Alex' SMAIL & EMAIL adresses: RR.1 BOX 303,

AND FROM A MORE RECENT EMAIL:
Well, I have good news and great news. Here goes. I made three replacement
LDR's. Two "soft" versions and one "hard" version. Am expecting some more
photocells so that I can make some more "hard" ones. The great news
is that as far as I can tell, bad LDR's can be fixed! The reason is that
the lamp apparently survives, probably because it is an 18 volt lamp operating
at around 6 volts. The photoresistor deteriorates. By carefully removing
the old photoresistor it can be replaced. The type of photoresistor and
the distance from the bulb is important, but by using an ohm meter and
a 6 volt supply, the optimum can be found. I find that out of a "variety"
pack of photoresistors from Radio Shack, two are ideal for my complete
combination "soft" version. I will write up a "how to" guide for Schober
SCHOBER DEMO ALBUM
LLOYD SCHEMPP wrote (in a recent email): "I do have a copy of the Schober
Organ Demonstration Album, a 12" record album, with demonstrations of music
played on the Recital, Theatre, Consollette, and Spinet. I am willing to
make copies for anyone interested for only the cost of postage and the
cassette". If you're interested; here's Lloyd's Smail & Email addresses:

MR. HARVEY TOOKEY now has Henry Nieschlag's Schober organ. Henry
notified me of the change and Harvey followed up by informing me that he
is now a Schober Orphan.

CASIO CT 370 KEYBOARD
BOB BAINBRIDGE writes that he has a Casio Keyboard for sale and I quote
from his messsage; "CASIO CT 370, 49 fullsize keys. Tuneable with 210 Sound
Bank Pulse Key Modulation. Operates on D cell batteries or 9 VDC power
supply. Price $73.00 plus UPS shipping. Universal 115 ac power supply for
above keyboard $10.00.
Bob continued; "Was originally purchased to add piano sound to a Recital
electronic organ but due to physical problems of old age owner never added
to console. Keyboard was used only to check for sounds and is therefore
in like new condition."
Contact: MR. ROBERT BAINBRIDGE, 15 WESTLAND AVE., QUEENSBURY NY 12804-1212.

PUFF OF AIR?
From: DAVID BRUCE: "I would like to know if anyone managed to get the old
air combination action working successfully? Has anyone found a method
of replacing the pouch pneumatics on those stop mechanisms? I would be
interested in details if anyone in the group has accomplished this. I am
trying to ascertain whether to try getting it working." If you have any
thoughts?, contact David at: David.Bruce@digital.com
