Michael Watterson, Ireland - Tube collection

Information - Help
ID = 14211
Photo Michael Watterson

Below you find a part of the tube collection Michael Watterson.

Generally interested in all old radios and useful old test gear. Particularly at the moment in valve portable gear. Also interested in Amateur Radio (Construction as much as operation).

I used to write articles on old and modern technology on my website Techtír.com (Technology land in Irish).

I still do some restores, but mostly write.
