In the ham radio environment, Soviet amplifiers are stillday are popular. Radio transmitters, acoustic systems for home theaters, electric guitars and other musical instruments are built on their base. One big disadvantage of lamp samples is that they need 220 volt AC power supply, since the power transformer can only work with it. Therefore, it is problematic to use such amplifiers in field conditions. And the size, weight, of these devices is very impressive. What low-frequency amplifiers produced by the Soviet industry?
"Electronics 50U-017S"
The appearance of this Soviet sound amplifiervery attractive - the silver body perfectly harmonizes with chrome-plated adjustment knobs. The power button is located on the left front panel in the upper corner.
Further, in order, the location of controls and display:
- The luminescent indicator, almost eternal, is able to last for a couple of hundred years for sure. You only need to properly care.
- Switching authorities of two pairs of speaker system.
- Bass and treble tone controls. By the way, a feature of this amplifier is the presence of filters that cut the high-frequency part and leave only the low.
- Control buttons loudness.
- Switching between Stereo and Mono.
- On the right side are the volume and balance controls.
The inconvenience is still there - a plug with 5 is usedpins, which now can not be found. But if you want, you can install adapters or completely get rid of the old connectors, installing in their place the new RCA. If you do not refine the amplifier circuit, then it is much inferior in quality to the reproduction of the ULF "Brig". But in all respects it wins in "U-101 Radio Engineering" or "Vega".
"Radio engineering U-7111"
This is one of the best Soviet amps, in itstime was the most "budget" option. But when compared with modern Chinese-made amplifiers, the U-7111 Radio Engineering is significantly ahead of them. The ULF kit included a tuner (radio signal receiver) and a turntable.
Externally, a very attractive amplifier, there is an equalizer with adjustment in five bands. The front panel contains the following controls:
- Button to turn on the "Mono" mode.
- Button on the high pass filter.
- Loudness
- Timbre adjustment at high and low frequencies.
- Volume adjustment.
On the rear panel are connectors forconnect sound sources - only four of them. A maximum of two speakers is connected to the ULF output. There is also a grounding terminal, fuse and sockets. In general, music lovers rate the sound as not bad, but out of 5 points, a maximum of 4 points is plus.
"Brig U-001": description
One of the best Soviet ampsTop class is the "Brig U-001". The sound quality is very high, but only if you use a good speaker system. ULF holds the bass very well, there are no extraneous sounds. When listening to music at high volume, the speakers do not lock up, which allows you to fully enjoy the music.
Medium and high frequencies are also transmitted.the amplifier is good - they stand out brightly, so listening to jazz, blues, orchestral music will be great. Everything is great, but the mass of the amplifier is more than 25 kg. With excellent playback of live music and movies, it’s worth talking about a flaw — rock and metal is uncomfortable to listen to.
Appearance "Brig U-001"
The front panel is silver in color and has the following controls:
- Bass and treble controls.
- Balancing the right and left channels.
- Loudness button.
- Button to cut the high frequencies.
- Headphone jack 5.25 (better to connect through the appropriate adapter).
Много положений у селектора выхода, что позволяет make the connection to the amplifier of multiple sources and speakers. And in the process of listening, you can quickly switch. In general, very high quality ULF, but only to buy it is more and more difficult, especially in the original version.
"Corvette 100U-068S"
Another Soviet amplifier, in some respects, is not inferior to the “Brig” described above, but overall a little worse.
On the front panel of the ULF there are such controls and displays:
- Adjustment of filters of high and low frequencies.
- Selector to select the input.
- Smooth loudness.
- The indicator of the excess signal at the output (overload).
- Volume control.
- Protection against short circuit, overheating.
- LED indicator.
When connecting an 8 ohm speaker systempower 60 watts, 4 ohms - 90 watts. Maximum power consumption - 275 watts. The huge minus of the device is a plastic case, since the mass of the amplifier is very large. The very reliable technical part of the amplifier is balanced by the poor quality of the case and controls.
"90U-2 Kinap"
You can’t pass by such a legend, sincewith his help most of the Soviet people heard the voices of their favorite actors. This is a Soviet tube amplifier that was used in mobile cinema installations.
The number of adjustments does not shock the imagination,As described above - there is a setting for volume, bass and treble, an overload indication lamp. Also on the upper part there is a window to which the device was connected, which reads the sound from the film.
On the tape, sound tracks were placed on the side,which are read by optical devices. 90U-2 were produced in the 60s, when the tape could be heard only in the KGB. In civilian technology, it has not yet been used. On the sound quality, perhaps, it is better to remain silent - it leaves much to be desired. But still, some musicians, fans of the “tube” sound, use these amplifiers as a base for guitar ULF.
If you want to play music, then better.choose one of the above Soviet sound amplifiers. Power supply 90U-2 from the 110-volt network, for connection to 220 V you will need to use a special unit. This does not add convenience, and the input for connecting a signal source of impressive size is about 4-5 cm in diameter and three holes. Even the euro-plug freely enters into these openings, it is not fixed.
