Amplifiers for electric guitar "Electron" and "Impulse-20" from 1973 and 1978, respectively, produced Kherson factory p / p. Amplifier "Impulse-20" is different scheme. TX on amplifiers yet. Here is a description of the amplifier "Electron" from the site http://oecc.ru/kombo/elektron-73.php: This instance, released in 1974, has a factory number 402, from which it can be indirectly concluded that the production of this model did not carry massive character. The design of the Electron amplifier is simple: on the wooden frame, equipped with a pair of wooden legs and two veneered "furniture" cheeks, an adjustment unit is mounted and, in fact, the chassis of the amplifying part. On the front side, covered with yellow radio tissue, there are two broadband loudspeakers 1ГД-35 and a label with a logo. On the top panel covered with black enamel are: power button with indicator, button for switching on amplitude vibrato, high-frequency button, which is analogous to modern Presence, volume controls, high-pass and low-pass filters, frequency and depth-control knobs. There are two SG-5 sockets on the rear panel, corresponding to the modern "Low" and "High" inputs. At the bottom of the combo is a board on which a voltage switch (110/127/220), a network socket, two 1A fuses and a SG-5 socket for connecting an additional loudspeaker are mounted. ELECTRON dimensions 54x33x15 cm, weight 9 kg. For the convenience of carrying the device is equipped with a spring-loaded retractable handle in the upper part. It cost this miracle 150 full-fledged Soviet rubles, that is, slightly above the average monthly salary of an engineer. From the point of view of exploitation, the combo causes contradictory feelings. On the one hand, ELECTRON has its completely unique voice, which cannot find analogues among well-known brands, such as FENDER, VOX, MARSHALL, etc.,. And the matter is not at all that it is a "scoop" and a "collective farm", but the fact that just the structure of a sound is like nothing - besides that it is "that sound", the sound of the 60s, irrespective of the "state" »Snapping.On the other hand, by modern standards, ELECTRON, of course, is absolutely not suitable for the performance of alternatives, heavy metal or grunge - its diocese of surf, rockabilly, rhythm and blues and mod-rock. Not harder. But in this category, he is definitely a worthy fighter. Its power is enough to sound the guitar at school parties, in small cafes, etc. For home use - especially depending on relations with neighbors. Among the shortcomings we can note the high level of the background and the fact that as the vibrato depth increases, the signal of the master frequency generator more and more penetrates into the playback path so that with the fully unscrewed Depth knob the amplifier can be used to emulate the sound of a flying helicopter.
