Thanks for all you replies. I had no idea that my question would generate so much interest.

I had been looking for an EMER or W.H.Y. with a parts list, but had no joy. You've come up with the goods. Thanks.

My dog kennel unit is actually labelled 5886 and rated at 180VDC 70mA. It delivers this fine into a dummy load, despite the rectifier valve being low, but I haven't checked the transformer temperature over a long period. There is no mains voltage selector switch and there is only one primary winding.

As I said, one or perhaps two, of the caps in question were inside the pitch filled choke can. I had to mechanically remove the pitch to get the o/c choke out. The cap I recovered intact was 0.01uF and 32mm square by 8mm thick, which made me think it was a high voltage type.
