Been updating my Studer A810, managed to get hold of a pair of VU meterpanels and a 4 speed controller which I have replaced th digital LED display and fader system.
Not an easy job as there is a fair bit of wiring and an extra circuit board for the old LED and fader interface and it isnt obviouse where to plug in the new VU panels even with the manual but I think I have it sussed now and it still sounds fab and looks better with VUs IMO
