How to connect the Gyro speaker to my Allen C-1?

[Arden]

I picked up an Allen C-1 with an Allen Type 90 "flute" speaker, but cannot get any sound from the speaker. I figured out how to connect it so the speaker turns and I can vary the speed, but still get no sound. On the right side of the cabinet, going up to the rotating speaker contact rings, is a small metal box with a transformer on it, marked "<U>amp</U> <U>com</U> <U>com</U> <U>lo</U> <U>hi</U>". There is a separate line (?) cord running to it, connected to "com &amp; com". The wire was just hangingloose when I got the speaker, so I assumed (perhaps incorrectly!) that this should have a male 110v connector on it. When I plug it into the mains, I get an extremely loud "hum". Perhaps this should be connected somewhere else?</P>


Any help will be appreciated!!</P>


Also, I need to get another speaker for the "diapason"; any suggestions as to what might work would be greatly appreciated!!</P>

Arden: Did you get any answer to your question yet? I looked a a couple of units I have and from what I gather, you might have hooked up 120 volts directly to the speaker line. Only the presence of a capacitor in series with the speakers, which are not designed to carry much bass, saved you from blowing them out. </p>

Norm, thanks for your help on the phone. I took your suggestion, and hooked the audio outputs into the amps I use for my keyboard - all the keys &amp; stops work great! Now all that's left for me to do is figure where to hook up the unattached wire from the unit on the side of the amp. the amp in the speaker does power up, but I get no sound... </P>


Perhaps someone else will have the answer.</P>

[:D] It works!! After fidling around with all the wires, I started turning things on the speaker amp - and found that the Master Gain was turned all the way to OFF!! A big DUH to me!! Also figured the wire in question is just to attach to an additional non-Gyro speaker. Another big DUH!! I'm in business for now.</P>


Thanks for this wonderful forum!! There is SO MUCH good info here.</P>

I forgot: one more question re the Gyro amp.</P>


When I plug the power lead in to the wall, the amp powers up. The Gyro relay doesn't power on till I turn on the organ. Is there supposed to be a relay / switch for the amp power, or does it just stay powered up?</P>


Thanks</P>

There's an AC outlet on the back of the big chassis in the gyro box that's meant for the amp to be plugged into. That way the amp only comes on when the gyro itself comes on.</P>


See my post on your other thread for more info on the wires coming and going to the crossover assembly.</P>


Glad you got it going. No need to feel bad about the pot being turned down. I've overlooked the simplest things in many cases!</P>
