So I have an old Hammond organ, nothing fancy but I love how it sounds. Anyways recently I noticed it has an output tucked away on it, all it says is 120 volts 60 hertz 2 amps. I can't find any info on this particular organ online.
So would it be most likely a speaker out I should only use with a cab? I haven't opened it up yet but I assume it has some sort of amp built inside, maybe a tube amp as it's from the 70's.
I have mic'd it before and it sounds amazing, it needs some repairs but it sounds great. Sadly the bass floor pedals often don't work, I need to check the wiring in the back soon...
Anyways should I avoid plugging it into anything? I have a cheap old guitar amp I could test it on.
My advice would be to try an unpowered speaker first. If there's little to no sound try the amp. Are you sure the 120v 60hz 2 amp isn't referring to the ac input? The 120/60 is standard outlet voltage. You could also plug a patch cable into the mystery jack and read the voltage at the other end of the cable if you have a voltmeter of multimeter. I hope this helps. Good luck.
