Thank you for your assistance guys.
Although I conclude from your posts that I don't necessarily need one (the 3 sets do have mains transformers) I nevertheless think, "yes", I will get one anyway.
I am very safety conscious and the warning about the possibility of the chassis becoming live due to a defective on/off switch is enough to convince me of the sense in having one. The rest of the advice regarding safety is welcome too, thank you. Fortunately I was already familiar with it, having served a pseudo apprenticeship working on battery powered sets. But the advice is still very welcome and appreciated. One can never be too careful eh.
Now I just need to decide whether to build a 240V equivalent of the Heathkit, or buy and enclose a TX. Decisions, decisions, decisions...
