I bought a pair of Revox 1970s tuners.
Just like in the A77 tape recorder of that period, the moving coil meters are falling to pieces. This is a well known illness of all 1970s Revox meters.
The glue used to hold the bearing "needles" to the coil and bobbin crumbles, and the armature falls out.
Also, the pointer itself is made from (I think) a narrow strip of aluminium, and whatever is in the glue caused this metal to corrode. Not only where the pointer was glued to the coil bobbin, but the corrosion has spread some distance along the pointer, so re-gluing it will be only a temporary fix - until the pointer breaks off halfway along. It's all very brittle.
I need inspiration on what to use to make a new pointer. About 0.75mm wide, and about 25mm long.
I had thought of cutting a strip out of a pie-plate, with two razor blades glued together 1mm apart.
Any other ideas?
(I'm now very pleased to have the binocular dissecting microscope I acquired a few months ago!!!! This repair would be impossibe without it)
