A GU50 - ГУ 50 - LS50 pentode.
Military equipment!
GU-50 is also used in the audio frequency power amplifiers.
The pentode GU-50 uses radio-frequency oscillator and power amplifier in the metric wavelength range of RF equipment.
Cathode: indirectly heated, oxide coated.
Envelope: glass, there is no basis
Operating position: vertical connectors down.

Welcome to the Webshop
The NOStubeshop webshop, an old "love" of the electron tube technology and its relation to rebirth, I created because of the needs that.
I thought that a lot of like-minded people rarely have the opportunity to visit these shops, on the one hand the lack of time and because there are very few of these shops. The Internet is now available everywhere in the postal courier companies to deliver it to all the goods.
Present specialties in itself.
Many old vacuum tube (NOS or operational use), is still not readily available, even from these few pieces trying to make up for the horrific prices instead áron.Segítek solid construction and repair advice is dealing with pipes for 35 years. In any case, I check the pipes IL-14 military vacuum tube tester and if needed also paired quad-sorting.
after prior appointment it is possible to choose goods on site as well.
I wish you a good time and all of our internet users purchase online store.
Thank interests.
