Gettin' my groove on

Recently, a friend at church let me have her old Hammond 9822M organ. This is one of those classic 70's keyboards that were common in homes at the time. The particular unit here works, mostly. The volume pedal is busted. There is a loud hum, possibly in the amp circuitry. I believe the hum is related to the pedal. Anyhow, I'm ordering a service manual for it, and hoping to get some advice from others who have modded these organs before.

My goal is to get this baby back into working shape, as even with the hum, it's got a classic sound like no synth today has. This guy contains actual Leslie vibrato, which probably means nothing to most of you folks, but trust me, that alone makes this baby worth restoring. Leslie speakers achieved a cool woo-woo-woo sound by spinning the actual speakers around on a shaft. It's mechanical. Technically, it might be more of a phase shift instead of a vibrato, sort of a Doppler effect thing. Something like that. Anyhow, I've got high hopes for this guy.

For those of you who have wondered, my site has been down for a few weeks now. I'll dialog about that particular experience later.
