would a mov rated at 500vac with selinium cell do the job?

I don't have the IC-720A schematic handy but is this the device that's wired in across the antenna connection?

yes its from coax to ground on chasis with a 33k resistor
thanks for replys

You don't even need it. The rig should work just fine with it removed.

It's really a lightning transient suppressor. An MOV won't do this job, it has too much capacitance.

If you have an external lightning arrestor that breaks down properly, this device is superfluous.

Thanks for all help but I have now tracked down the part direct from Icom UK should be with me in the morning..
