Below you find a part of the tube collection Bryce Ringwood.

For reasons of space have to keep the collection down to a few. I repair vintage radios as a paying hobby. I keep records of them for interest. Call sign used to be G8ARY many years ago when I lived in UK. I began my hobby by building a crystal set radio using Ivalek headphones, Repanco coil and Jackson Bros variable capacitor (which I still have!). It really didn't work very well. I used to listen to short wave on my Dad's radio and later on a Wireless Set No. 19. I tried without success to receive the first Sputnik using an R208 receiver on 20 and 40 MHz. I built my own receivers and transmitters for the amateur 70cm band and had a contact from Leeds in the UK with a Norwegian station using my 4X150A homebrew transmitter. Before leaving England for South Africa, I hurriedly built a five band shortwave receiver to listen to the BBC. On arrival, I more or less gave up radio for 20 years until a colleague presented me with a very broken NC 100. (Meanwhile, I had been very busy making electronic equipment for strain measurement and helping my children with radio control.) The NC 100 seems to have acted like a magnet, attracting all sorts of strange equipment to make a collection of sorts. My Wife bought the Phantom de Luxe for my Birthday.
