Hammond AO-39 and AO-35 organ to guitar power amp conversion

Post by Tubelube »

I have two Hammond AO-39 and two AO-35 organ power amps that I am looking into converting into guitar power amps with pre and post volume controls. Any rack mount guitar preamp could be used with them. This shouldn't be hard as they are organ power amps to begin with; I'm not trying to convert them into full guitar amps. Do you have any thoughts as to where I could obtain the needed info? Best Regards! :D

http://el34world.com/projects/StereoPowerAmp1.htm -- Not a Hammond conversion discussion, but should give you some idea of what you need to strip out/leave in/add/change to end up with working power amps.
