Conect 121 Lathe - The toy collection grows!

After some tinkering this afternoon, I may have an issue with the spindle board/motor/choke.

The manual overide doesn't work, so started of by bridging the start connector on the spindle board (it's a Control Techniques ASP-5 with symbols drawn on for the motor/control connections), which would let me up the speed to maybe 50-60rpm, before it would start grumbling/hesitating a lot before either blowing the 13A fuse in the plug, or tripping the 32A ring main circuit breaker.

Does Emerson still manufacture ASP-5? My understanding was that they have been obsolete.

Here's a list of current Control Techniques DC drives. I believe even some of them on that list are obsolete.
