First, an apology: I used to have a links section to direct you to other resources that I find helpful. Way back, this “disappeared” and I resist taking on computer issues! I knew that I was not reciprocating with people who have added me to their sites and “something happened” recently that caused me to do something about it. It may seem to some that I am either selfish or arrogant (you may be right) and I apologise to friends and all others who maintain excellent sites that have not been acknowledged here (for a long time, anyway).
Antique Radio Forums: A friendly and excellent US based forum on all things related to vintage electronics.
UK Vintage Radio Repair and Restoration: An excellent UK based forum on all things related to vintage electronics.
Oregon Tektronix Museum: These guys, mostly old (and perhaps not so old) hands from Tektronix, had a vision to create a bricks and mortar Tektronix museum. They put their money where their mouth is, fantastic!
Radiomuseum: A searchable German based museum mostly on vintage radio but many other things too, including obscure data. You have to be a member to access the full information on each item.
Oscilloscope Museum: My friend Volker Klocke’s site covering mostly european instruments, a must see.
Online Museum and Technical History of Hewlett-Packard (now Agilent Technologies) Electronic Test Equipment: My friends Kenneth Kuhn’s excellent site. Kenneth is a brilliant engineer and all around polymath (IMHO), also extremely supportive of amateurs such as I.
Kurt’s Tektronix Page: Tektronix repair blog, extremely informative.
TekWiki: A must visit if you want to know about an item of vintage Tektronix gear including both technical (and in some instances manual downloads) and historical information.
Greentrace: A showcase of mainly british scopes.
The ValvePage: A british site showcasing vintage radios, tvs and various test equipment.
HP Memory Project: Marc Mislange’s amazing home museum located in marvelous Basque country, VISIT THIS SITE, extraordinary. I have visited Marc at his museum / home, he has an example of pretty much everything HP made prior to I am not sure when. From the tube era well into the ultra high-precision solid state era.
The National Valve Museum: Marvelous site with data and history on a wide variety of types and makes. If you like valves and have not yet visited this site, DO IT!
