The power to the bench is protected by RCDs, and my test leads should be up to Cat III standards, but of course there is no such thing as being 'too careful' when dealing vith high voltages.
And to add to this, I should say that an isolation transformer is only to provide a means of safely connecting earthed test equipment to the live part of the circuitry - nothing more. There are a lot of misconceptions about isolating transformers. We've covered them in the past: http://golbornevintageradio.co.uk/forum/...p?tid=4593 - for anyone reading who is any doubt, that thread covers the ground fairly well - and gives some examples of the sorts of misconceptions that exist.
