Russian Factories of Vacuum Tubes

Russian/Soviet Tube Factories and their Logos

HELP PLEASE

If anyone has information to add here, please let me know!

	Svetlana Electron Devices, St. Petersburg: Svetlana is a Russian woman name, which means "light". The major and oldest Russian power-tube manufacturer, still in business today. Formerly a part of the huge Svetlana collective factory, now independent. Legal problems about the brand name have been solved in such a way that New Sensor Co will not use the Svetlana brand for Europe any more. Today, new production is cleary devided in S-logo from the Ukraine, and genuine C-Logo from Petersburg.
	Ryazan Plant of Electronics, Ryazan: Makes power triodes for RF and audio applications. Some are sold outside Russia by Svetlana Electron Devices. Ryazan has also made large thyratrons and pulse tubes. Types in production: 811A (popular and sold all over the world), 812A, SV811-3, SV811-10, SV572-30, SV572-160, GM-100, others. SV types and 811A are made especially for Svetlana Electron Devices.
	Reflector Corp, Saratov: Makes most of the tubes marketed by New Sensor Co. of New York under the Sovtek brand name, Tung-Sol, Electro Harmonix, Svetlana S-Logo, Mullard. Some of these are old Russian types, others are made especially for export. Types in production: 12AX7 (three variations known), EL34 (2 versions), 6550WE, KT88, 300B, 6B4G, 5AR4, 6L6/5881 (3 variations known), 6922, 6EU7, 7199, EL84 (2 versions), 6P15P. Sovtek also markets 5U4G, 5Y3GT, 6SN7, 6SL7, two 12AX7s and a few other types made at other factories. New Sensor (sais) to own the Reflectro factory.
	Ulyanov, Ulyanovsk: Large state-owned factory specializes in military eqipment. Also makes tubes for use in military aircraft electronics. Continued production of tubes below cannot be confirmed at this time. Types in production:GU-50, GU-13/813, 6S33S-V, 6S19P, 6S41P, others. 6S33S-V (often kept in Cyrillic form, 6C33C-B) is becoming popular in high-end amplifiers in America and Japan.
	Voskhod, Kaluga: Large collective factory, makes many ICs and other semiconductors as well as receiving tubes. Types in production: Makes 6N1P-EV, 6AX7, 12AX7WA/WB, 6SN7, 6SL7 and a few other types sold by various firms outside Russia.
	Novosibirsk: Large collective factory, makes receiving tubes. Continued production could not be confirmed at this time. Types in production: Unknown
	Orel: Moved to the hall of NOS tubes :(
	Poljaron, Lvov (Ukraine): Makes 833A and some Russian ceramic power types, plus related products such as vacuum capacitors.
