Anyone have a data sheet for these ???
1 Attachment(s)

Picked up a coulple of boxes of vintage radio parts and these were in there. I have no idea of the ratings but would like to use them at some stage. I have done the usual Google search....nothing:confused:

They are quite large 68mm x38mm & 47mm x 35mm

Any help would be great

Open them up and look at the diodes inside...they might have traceable numbers on them.

You will destroy them. They are selenium rectifiers. The one on the right is a 250V 100mA bridge, for the left one you should look for another indication.

Or post your pic in the tube section, they should be familiar with that kind of component.
