When I have the main speaker turned on and antiphon off, I still get about half volume (actually probably more like 80%) out of the antiphonal. When I turn off main and antiphonal off I get nothing out of antiphonal. Is it normal that I should be getting sound out of the antiphonal even when it is turned off when the main is on? Why can I play with just antiphonal, but not just main? Do I have something hooked up wrong? Thanks for your help and opinions. I'm learning so much from all of you on here.

Must be something wrong with your relay, a short or near-short between the movable part of the antiphonal relay and the main speaker output. Check with a meter and look for a flaw. Possibly a wire whisker.John

Hmm, Ok. I have a meter but could you explain how/where to find this relayand the possible short? Thanks.At home: Allen T12 B, At church: Patrick Murphy Pipe organ. The console is a rebuilt Moller.Comment

Find the speaker cabinet (main) and inside you'll probably find the amplifier. Follow the output from the amp and it will go into the relays. The relays on the old Allens are very simple open-frame devices, so you should be able to see the leaf switches and such. Disconnect the wires from the relay and check it for shorts. Of course, if the problem is a wire whisker, you'll see that before you even start disconnecting things.John

Jan Giardot has compiled a nice ring binder with a lot of helpful information on early Allen organs and separate pages for notes you'd like to save. Look for one of his post and he'll be glad to give you information on how to buy one.Comment

Problem resolved. When I took the organ out of the church it was in, I disconnected the speaker wires from the speaker end. Therefore, I assumed that everything was right on the organ end. When I was inside the organ searching for the possible short, the problem was real obvious. The 2 white wires were hooked to the terminal marked Antiphonal, 1 black to the main terminal and the other black to the common terminal. Now I have both blacks on common and the correct white wires on the antiphonal and main terminals. It now works correctly and I can use either speaker alone or both together. Am I correct that black should be the common?At home: Allen T12 B, At church: Patrick Murphy Pipe organ. The console is a rebuilt Moller.Comment

Yes. Black is common inside Allen consoles and speakers. Good troubleshooting!John
