Found this through google, searching on the words printed on another poster's picture of a MB cruise amp: "VDO Tempostat"

This is from one of their UK distributor's website.
I was curious if any members have ever seen or used one of these in north america?
The price is out of sight in the UK. If one could be obtained here for less than the price of a rebuilt or new MB amplifier or other $$ component, perhaps it would be an easy job to plug the column mounted MB selector harness into this one's control box and you'd have it all done. That is, providing it's a VDO unit that you have.
