Hammond M3 - How to add 1/4" output to leslie or phones OR still use speaker

[proche3]

Hi,

New to the forum and inherited a 1959 Hammond M3 that I am so excited to play! It is all stock components with original bench, no modifications have been made to it. It's fantastic! BUT this summer I'd like to be able to run it through my dad's 122 Leslie. I saw one post at the link below, but I'm just not that great at reading and understanding his schematics, or making sense of the posts afterwards where better solutions are shared. I was wondering if someone has the definitive answer on how to properly wire the M3 so that you can choose between the built-in speaker, an external Leslie or Headphone levels. A video or detailed pictures and parts list with current manufacturers would be amazing. I am hoping someone on this forum has got my back! These are amazing organs, I really want to bring the best of out of my M3 for my home studio. Thanks in Advance. :-)

As you have seen in the archives, there are many different ways to achieve what you need to do.

I would start by installing a line out with the option of silencing the speaker. I've attached a design I normally use although you can purchase one from trek ii. http://trekii.com/products/obl-2-sl.html I would then use a small mixer connected to the line out to drive headphones. This gives you the option to insert an effects box.

A Leslie 122 - 6H connection type, requires a balanced input and a transformer to change the audio ground reference for speed switching. The 122 kit for a M3 is 8010. However if you handle the speaker load with the line out box, other 122 type kits which are more readily available can be used.
