Description: Silicon NPN transistors KT3102EM Lot for 30 pieces Made in USSR by 1991. Please note that photos of guitar consoles are for informational purposes only. I only sell transistors. Here is a lot of 30 popular and widely known Soviet silicon transistors KT3102EM. These transistors gained wide popularity thanks to a whole line of famous guitar consoles Big Muff produced by the famous company Sovtek in the 90s. I found a rather interesting story about these transistors on the Code Effect website and I want to share this story with you. I hope these guys won't be mad at me ;) History of the Big Muff Russian: The Big Muff was originally released in 1970 by Electro Harmonix. However, the company declared bankrupcy in the 80s. In the late 80s, Mike Matthews decided to buy an old Russian military factory ExpoPul located in Saratov, Russia, to produce vaccuum tubes under the name of New Sensors. EHX was back on track! Mike Matthews met in the 90s two Russian colonels (True story!) running a factory making military training equipment, integrated electronics equipment quite close to guitar pedals. Meanwhile, many people asked for a return of the EHX Big Muff. The production then began in the Sovtek factory! The first pedals that got out of the factory were the Red Army Overdrivre (ultra rare) and the "Civil War" version of the Big Muff. This is why there is a star logo with a bird on the side of the pedal, which is the Sovtek logo. PCB is populated with film capacitors, carbon-comp resistors and of course 4 transistors like every Big Muff. The PCB is huge... As for transistors...They are unmarked, except for the white and green varnish dots on it. I did a bit of research and they are KT3102EM transistors. They are npn transistors with a hfe between 400 and 1000. A modern equivalent are the 2n5088 transistors. This Big Muff is known for its massive sound with a lot of bass.Actually, the tone circuit let quite a lot of bass go through it, and coupling caps have higher value than traditional Big Muff versions. It is really a hell of a pedal. There is a massive sound going out of this box, it is very impressive!
