Does any body Know what these EL84'a are

Post by Brewmaster »

I came across a set of El-84's labeled Hammond and made in Austria. Does anybody know who made them?

Can you read the small codes visible near the base of the tube. If you can, look on this document

Both have the following codes:

kM4
A7D4

I did not see them on the doc.

Thanks for the link though! :)

Hi, It is the A that denotes the manufacturer so they should be made by

Wiener Radio Werke

see

Do they look like these? Note the very similar codes

Bear in mind rebranding was very common at that time but the codes are correct!

I couldn't that lucky. These don't have the round hole in the plate like the Mullards in the pic but have a rectangular slit like in the Philips link.
