Yes I picked up on that earlier, it was an auto-transformer. If you can sort the heater for your future project, it will do a good job.

I don't like the idea either, safety apart, a live chassis is a pain when it comes to connecting to test equipment, indeed, connecting to ANY other equipment. I may be able to help - I have a project in the 'day job' which is a one-off, but will need a low-power isolated supply and for quickness I'll be using an off-the-shelf small toroidal transformer, modified. If so I can get an extra one modified for you. Will send you a PM.
