Dear Ladies and Gentlemen, Yes, they’re still available! The premium TELTRON and NEVA electron tubes are still in stock in their proven excellent quality and at their traditional low prices. World-wide there are only a few locations where electron tubes are manufactured. Only specially trained experts with many years of experience have been able to master the technically demanding manufacturing process necessary to guarantee consistently good quality. Our location in Klingenthal / Saxony fulfils these strict requirements. This is where we produce all of our tubes. On the following pages we have...

Highly evacuated electron tube with focusing electron gun, fluorescent screen, and Faraday cage positioned on one side. For demonstrating the negative polarity of electrons and estimating the specific electron charge (charge-to-mass ratio) e/m by magnetic deflection into the Faraday cage, which is connected to an electroscope ( ­P-1003048). It is also possible to investigate the deflection of electrons by two magnetic fields at right-angles to each other and to demonstrate the effects, for example by generating Lis­ ajou figures. s Filament voltage: 6.3 V AC Max. anode voltage: 5000 V Anode current:...
