On a French forum, I found a 4 pages PDF scan of an article published in Nov 1932 in Electronics magazine.
It talks about an RCA ribbon mic with an integrated 3 valves amp. Pics and schematic included...

Sorry if this has been posted before, but my search and a look at the meta returned nothing.

The link to download the article is there:

It is the link in the first post. Don't worry, the whole article is in English!
