Tube Leslie Connection Mod

[Drawbar Dave]

I have found a way of making the connection to my 147 a bit safer.In my small studio the back of the Leslie is against the wall and I am worried about the rigid cable pulling the 6 pin plug to the side. I found some of these amphenol "back shells" in my spares box. It recesses the plug nicely so there is minimal sideways movement. These back shells often appear on ebay. They do not work on solid state PSU's though as the circuit board would clash with it.

The black cable on the right is another modification I did today. One end is soldered to the brake jumper plug and the other to an in line lamp switch so that the slow motors can be switched off.

What a great idea!
Seen the hardware before, just never thought of using it on a Leslie.

One teensy thing of probably no importance. Because you're pushing the plug against the can, I might be inclined to use a small nut-bolt fastener instead of a sheet metal screw to hold to the chassis. It probably holds fine as-is, just throwing that out there as a thought.

It's an interesting idea, but it will not work with the now-standard plastic end-caps on Leslie cables or the older heavier metal end caps. Neither of those would fit into the recess. It will only work with the black metal shell types.

[Drawbar Dave]

Yes that is true. It works for me as the Leslie does not leave the studio although it does get moved around. All my Leslie cables have the same ends on them. If I was playing out I'd use a box mounted in the Leslie with a more robust connector and have a short run of cable into a vintage 6 pin plug. I first saw these recessed back shells used on the Bill Beer Hammonds and Leslies.

Unless you're running a rental agency and send out solo Leslies it doesn't matter.
Or unless the world supply of Amphenol connectors dried up, it doesn't matter.
So beware, in case all that happens.

Otherwise, yes, what works for you is great.

Looks cool. And it lessens the chance for the thunderstorms when the plug gets bumped.

Would only use metal plugs anyway.

I use these and strap that end down when at backline venue.

I believe these are called MS21919. They come in a huge variety of sizes and configurations. Commonly called "P-clamps."

Now my curiosity is up - gotta look up the number to be sure.
