Thinking out loud 3-500Z and the like gettering with RF?

I have seen on Ebay and Alibaba small to medium RF induction heating boards for sale for not a whole lot of $$.  Has anyone tried to use one of these in a setup with a coil of suitable size to cherry the plates of a 3-500Z or 572B?
In theory it should work OK and it would be a lot safer than running 500 V or there about and positive grid voltage to cherry the plates.  The tube manufacturers used this setup in production to flash the getters on smaller tubes.   Your thoughts??

Thanks,
Randy AB9GO
