You cannot put an MOV in series with the load, as you have shown,
because it has a high resistance, except during over voltage

Thanks for the advice. I've obviously misunderstood the use of MOV's.

I'll put one (I'll have to check at home to see what rating it is) in
parallel across my RC (LCR - combined 100R and 0.1 Cap)
