[QUOTE="marcochezzi, post: 958402, member: 21001"] The switches themselves can be gotten to after some considerable dismantling, I have to admit that this is the first Revox I have ever owned, and only the 2nd that I have ever looked into, the first being an A77 I helped a forum member get going, albeit a simple repair requiring a small short on the remote plug to get her spinning again.. Anyway, I digress... The physically broken switch was not functionally broken other than the switch shaft having been snapped off. Those shafts are available as replacement units on ebay at a dime a dozen, if you are prepared to wait for the inevitable 6 months SA Post Office delivery schedule, and if you are prepared to venture into the guts of the thing... Patience is not my forte, I have recently recapped this unit, and I am dying to try her out, preferably with a functional switch.. So I got to stripping, got to be careful with these things, the switch halves are held together with a double acting rivet of sort which needs to be carefully ground away, after which she can be split, carefully - there's a spring in there... This is what was left of the shaft.. [IMG]https://i.imgur.com/TjLUX6I.jpg[/IMG] [/QUOTE]
