The meter on my AVO VCM has gone open-circuit.
The movement is undamaged, swinging freely as it's
now undamped.
Is there a repairer in the UK anywhere ?

Test Instrument Services
at the same address.
Contact them and please report back whether they still do or do not.


Emailed Inmar, but no reply so far.
Found a company (Glanford Electronics Ltd.), who offered to have a go,
but it didn't sound very hopeful. I've sent it to them, but still awaiting
the outcome.
But I've since found another company (Crowthorne Tubes Ltd) who
offer a replacement moving-coil movement which can be installed in
the original Avo meter case, and using the same dial. Their trick is
to use a 1mA movement (much more robust than the 30 microamp
original Avo one) and feed it with a suitable opamp! Neat!
