This particular meter was bought in London, at the end of the ’90s, in Camden Town market. Good meter, at that time was very responsive and dead accurate. Last year I noticed a failure in accuracy and send it to Ian Partridge of www.ian-partridge.com .
He replaced the cell, re-soldered everything, cleaned the meter innards, adjusting it, etc.
Did a very good job, thanks Ian! It’s a good feeling to know that your precious tool has been given a new life.
