Default Re: Eddystone S640. Mains primary open circuit.

I tried the bucking transformer and it worked really well hardly any voltage drop when loaded. I ended up with around 215 volts, it was a 0-17V 0-17V secondary.

In the end I found an autotransformer with a 200 volt tap so will use that while I go through the restoration. Noting of course no mains isolation is given by either method. Meanwhile I will keep a lookout for an origional replacement or a transformer that will fit in the shield of the origional. Colin.
