I'm a collector of vintage electronics and designer of circuits involving them. I'm collecting these parts since the beginning of the year 2014 when i saw a post in an electronics forum. I started with a few experiments with tubes and control electronics. As i found out how many different tubes there are, i started collecting them. Currently i have about 70 different types of tubes (March 2016) but from time to time this collection will grow. As searched for Information about Nixie Tubes, i found out that there were alot of other display technologies such as panaplex, numitrons and vfd tubes. Im collecting these too.
