FrankenPilot? ST4000+ and linear actuator?

Hi everyone,
I was given this control head when my father upgraded his autopilot. It was used with a wheel drive (he kept the old drive as a spare) and I'm trying to convert it to a tiller.

Is It possible to use a 2005 vintage ST4000+ control head to drive a linear actuator vs a Raymarine tiller drive?

One of the things holding me up is I'm unsure about is what the maximum output amperage of the motor drive circuits are? It appears like its a simple pulse type speed control.

Am i correct in assuming there is no feedback from the tiller drive?

This head is the same as the 5000 that could drive a Type 1 drive. They burned up alot which is why they are no longer made. If you mount it out of the sun you will have better luck. There is a master setup mode you need to get into to change to the 5000 format. Raymarine tech may be able to help you with that.
