Default Re: Taut band meter repair- Ferrograph RTS2

Thanks Retailer,

I was looking at clock hairsprings yesterday, but they are mainly listed by the tension force, rather than physical size. I shall however measure the size & then have another look. It is a flat cross-section, as would be expected.
Other than that, I have seen a 1mA version of the meter, so if all else fails, I might fit that with an op-amp.
