Anytime from next week, collecting the thing on Friday and will need to learn how to drive it    :sd:

I don't care for trumpets on the hubs on vertical machines as they just add to poor gripping tension of the hubs with more "outboard" weight and Revox hubs are among the worst for poor hold down.

That's interesting Chris, I must admit that I have not noticed any hold down issues on mine, in fact there is a fair amount of tension between the reel plate on spool on both my units on testing, however I do respect your statement in this regard as without doubt the tension and hold down force on the Otari collet mechanism certainly seems better and stronger to me, not to mention truer centering of the reels, accepting some reel nab diameter tolerance in the mix.

Truth is I have always liked the appearance of the Revox crowns, which is why I am going full circle again in terms of designing and machining a Revox crown look with collet clamping system, its going to be interesting and just maybe a one off..

Lets see if I can pull this one off, good thing I did not damage any original parts..

I really do want to see your MTR10, will keep in touch.. :thumbs:

What a day yesterday - 825km round trip and got to see and experience BOP Studios! An absolute triumph of a place heading into oblivion. Heard that fabled Kinshito Monitors too
