You may have gathered I'm not a fan of Thorn AVOs. Is it really worth having a centre pole movement re-worked, only to fit it into a meter with crummy switches and unstable cermet resistors, with a few shunts thrown in which generally function as fuses? New boots will also be required on the buttons.

So, would you even bother to repair a Mk V when you can still get a good Mk III for relatively little money? The "proper" AVOs are almost everlasting when fairly treated.
