John Koster, Holanda - Tube collection

Below you find a part of the tube collection John Koster. In 2004 I started collecting radios, loudspeakers and other items, mostly from the period before the Second World War. The first radio I bought was a Cossor 464. I bought this radio on a flee market in Amsterdam in 1994, but it stopped there. In 2004 I rediscovered parts of the crystal and diode radios that I made as a boy and I decided to start a radio collection. My radios are placed in a number of radio cabinets. These cabinets consist of a number of segments made of chipboard with beech print. The back panel of each compartment has a socket outlet and an antenna connection. A small "La Pico" AM transmitter works as a "home broadcasting station". A number of radios can be switched on and off with a remote control unit, that operates the socket outlets. More info on my website: see URL below.
