Siemens Ediswan type R2135 (what is it)
Hi folks.
Please see attached photos. I have come across this whilst cleaning out the loft, It was my grandfather's. I was wondering if somebody could help me identify what exactly it is and if it has much worth? Many thanks for any help Regards Dan |

Stabilised HT power supply looks likely. The 12E1 is a valve designed for series regulation and the word "Stabiliser" is a strong hint!
Nice piece of kit, I wonder what its specs are?

Looks like a voltage stabilised power supply, I doubt it’s worth very much at all apart from parts.

It would make a good bench power supply for anyone working with valves.
Don't just plug it in as some of the components in it will have absorbed moisture from the air over the years. It is worth keeping intact. |
