Just ignore that 5-pin Amphenol connector on the back of your AO39 amp. It is there to connect a Hammond Tone Cabinet to the organ. You could rewire it, and maybe hide your hook-up kit inside the AO39, but the easy way out is just to add on a Leslie hook-up kit. Unless you have the ultra-rare A-100 with the finished back, and you don't want to add holes. You can buy the 6147 kit from several on-line sources, or you could build your own. The stock hook-up for a 147 / A-100 combination is what I saw someone post in response to your question. The AO39 outputs (speaker leads) feed the Leslie. You use a Tremolo switch to control Leslie speed (with AC switching), and an Echo switch to select either organ speakers, Leslie, or both. The console load selector on the 147 amp must be set to 8 ohms! You get Reverb only through the organ speakers. The kit is ridiculously simple. Just a small metal box with one 6-pin connector and some wiring. No other components needed for this hook-up. I recently did this same hook-up. I was too cheap to fork over the $150 or so for the kit, so I did my own. Well, also, I decided (as always) to be difficult. I wanted to supply the signal to the Leslie directly from the G terminals on the A-100's AO28 pre-amp. I mainly wanted to do this to perfect a hook-up schematic so I can hook a 147 up to my old BCV (something that God, and Don Leslie never intended). I ended up using the transformer that was in the 122-style hook-up kit that came with the A-100 when I bought it to convert the balanced (2 G terminals) output of the AO28 into an unbalanced signal (1 G and ground) for the 147. If you are going to keep the internal speakers in the A-100, I'd go with the factory recommended hook-up to the speaker leads, and live with Reverb at the organ only. Why complicate things? It's a very easy hook-up. Let me know if you need more details. BCV-KG -----Original Message----- |
