MOS-1 900-D Amplifier Question

[Jramsey]

My Friend and I just acquired an Allen MOS-1 900-D organ with a rack of 6, 100 Watt (T-100?) amplifiers, no speakers sad to say. My question is regarding the output of the amps. There are 8 ohm, 100W resistors hanging on the outputs of each amp that look like they were wired in series with the speakers.

Why would this have been done? I thought maybe the T-100 amps were not able to match 8 ohm speakers, or maybe they had paralleled two 8 ohm speakers bringing the total impedance to 4 ohms which might have been too low for the T-100 amps.

Hopefully John, Toodles, or someone will have seen this before.

Thanks much,

John R

Somebody was probably making up a crude way to tap the organ output for a sound system. Just ditch the resistors and connect the amps to 8 ohm speakers.

Thanks John...I thought it was pretty strange, and didn't think Allen would do something like that.
