I've changed my mind over which tubes to use in 'The Brute', I'll still be using EF91's for the 5" deflection but for the 1" tube I'll use the 9002's...just for the heck of it.

AncientBrit wrote:Steve, re symmetrical drive to 1 inch scope. I was worried that I would run into the rails with single ended drive so I opted for push-pull.
AncientBrit wrote:You are correct that the tube is designed for single ended drive on the Y plates, and yes, there is some slight defocusing and geometric error when driving Y push-pull. It's a pity that a few more pins were not available for Y2, and for manual setting of the focus. Having said that, the focus is sharp and amazing for something 40years old. Regards, Graham
