The Best Soviet Amplifiers: Photos and History

Technologies

In the environment of radio amateurs Soviet amplifiersday are popular. On their basis radio transmitting devices, acoustic systems for home theaters, electric guitars and other musical instruments are built. One big minus in tube copies is that they need to supply a variable voltage of 220 volts, since a power transformer can only work with it. Therefore, in "field" conditions, such amplifiers are problematic to apply. And the size, weight, of these devices is very impressive. What kind of low-frequency amplifiers were produced by Soviet industry?

"Electronics 50У-017С"

The appearance of this Soviet sound amplifiervery attractive - the silver case perfectly harmonizes with the knobs of adjustments covered with chrome. The power button is on the left of the front panel in the upper corner.

Next, in order, the location of the controls and displays:

  1. Luminescent indicator, almost eternal, can serve a couple of hundred years for sure. You just need to look after it right.
  2. The switching bodies of two pairs of speakers.
  3. Tone controls for low and high frequencies. By the way, the feature of this amplifier is the presence of filters, which cut off the high-frequency part and leave only the low one.
  4. Loudness control buttons.
  5. Switching the "Stereo" and "Mono" modes.
  6. On the right side are the organs for adjusting the volume and balance.

Inconvenience still available - plugs with 5pins, which now you will not meet. But if you want, you can install adapters or completely get rid of the old connectors by installing a new RCA in their place. If you do not modify the amplifier circuit, then the playback quality is much inferior to the ULF "Brig". But wins in all respects in "Radio Engineering U-101" or "Vega".

"Radio engineering U-7111"

This is one of the best Soviet amplifiers, in itstime was the most "budget" option. But if we compare it with modern amplifiers of Chinese production, "Radio Engineering U-7111" significantly outstrips them. The set of ULFs included a tuner (receiver of a radio signal) and a turntable.

Soviet sound amplifiers

Outwardly very attractive amplifier, there is an equalizer with adjustment on five strips. On the front panel are the following controls:

  1. Button to activate the mode "Mono".
  2. Button to turn on the high pass filter.
  3. Thin compensation.
  4. Adjusts the timbre for high and low frequencies.
  5. Adjust the volume.

The rear panel contains connectors forconnection of sound sources - there are only four of them. A maximum of two speakers is connected to the output of the ULF. There is also a ground terminal, fuse and sockets. In general, musicians rate music as good, but out of 5 points the maximum is 4 with a plus.

"Brig U-001": description

One of the best Soviet ampsThe highest class is "Brig U-001". The sound quality is very high, but only if you use a good speaker system. ULF very well holds basses, there are no extraneous sounds. When listening to music at a high volume, the speakers are not locked, which allows you to enjoy the music to the fullest.

Medium and high frequencies are also transmittedthe amplifier is good - they stand out clearly, so listening to jazz, blues, orchestral music will be great. All is fine, but the mass of the amplifier is more than 25 kg. With an excellent reproduction of live music and movies, it's worth talking about a disadvantage - rock and metal to listen on it uncomfortably.

Appearance "Brig U-001"

The front panel is silver-colored and has the following controls:

  1. Low and high frequency controls.
  2. Balancing of the right and left channels.
  3. Loudness button.
  4. Button for cutting high frequencies.
  5. Headphone jack 5.25 (better to connect via the appropriate adapter).

Many positions have an output selector, which allowsto connect to an amplifier of several sources and acoustic systems. And during the listening process, you can quickly switch. In general, very high-quality ULF, but that's only to buy it all more difficult, especially in the original performance.

"Corvette 100U-068C"

Another Soviet amplifier, by some parameters is not inferior to the above-described "Brig", but overall a little worse.

Soviet tube amplifiers

On the front panel of the ULF there are such controls and displays:

  1. Adjustment of high and low frequency filters.
  2. Selector to select the input.
  3. Smooth thinning.
  4. Exit signal level indicator at output (overload).
  5. Volume control.
  6. Protection against short circuit, overheating.
  7. LED indicator.

When connecting an 8 ohm speaker systempower 60 watts, 4 ohms - 90 watts. The maximum power consumption is 275 W. The huge minus of the device is a plastic case, since the mass of the amplifier is very large. A very reliable technical part of the amplifier is balanced by poor quality of the case and controls.

"90U-2 Kinap"

You can not pass such a legend, because it is withhis help, most of the Soviet people heard the voices of their favorite actors. This is a Soviet tube amplifier, which was used in mobile cinema installations.

Soviet high-end amplifiers

The number of adjustments does not shock the imagination,as described above - there is a setting of volume, bass and treble, an overload indication lamp. Also on the top there is a window, to which the device was connected, which reads the sound from the film.

On the side of the tape, sound tracks were recorded,which were read by optical devices. 90U-2 were produced in the 60s, when they could hear about the magnetic tape only in the KGB. In civilian technology, it has not yet been used. The sound quality, perhaps, is better to remain silent - it leaves much to be desired. But anyway some musicians, fans of "tube" sound, use these amplifiers as a base for guitar ULF.

Soviet amplifiers

If you want to play music, it's betterchoose one of the above-mentioned Soviet sound amplifiers. Power 90U-2 from the network 110 volts, for connection to 220 V you will need to use a special unit. This does not add convenience, and the input for connecting the source of the signal is impressive size - about 4-5 cm in diameter and three holes. In these holes, even the euro-plug freely enters, is not fixed.
