It is now fully functional copy, unfortunately without the original parts. As you can see, power amplifier uses:

  • the beautiful 6P3S tubes at output stage,
  • the 6N8 as a phase inverter,
  • the EF183 as microphone preamplifier and
  • EF80 as gramophone preamplifier.

As the result of long-term "residence" in the wet room, all the paper capacitors were "dead", and so the most of the resistors.

Under the name of A. R. Electronics hides Audio Electronics Company - a small workshop producing tube amplifiers in Gdańsk. For the first time I saw a product of this company at the end of the 90-ies of the last century, when I became the happy owner of the amplifier with the symbol SE-41. Unfortunately, I do not know if the company still exists, because for some time I have no information about new A.R. Electronics amplifiers. Anyway, in the secondary market one can meet the A.R. Electronics amplifiers characterized by good sonic parameters and interesting design line. Despite the lack of information in the official offer, A.R. Electronics produce or produced not only amplifiers but also other audio equipment such as tube preamplifiers. They were made to individual order or in a small number of units. To this type of products belongs a tube preamplifier with the symbol PL-02.

QUAD 22 preamp was designed to work with one (mono system) or two (stereo system) QUAD II amps. Its features, in particular, interchangeable external modules predestined it to act as an audio system control device. This has been reflected in the name of the device, which identifies them not as a typical preamp but the control unit (full, original name is "The Quad 22 Control Unit." Due to the fact that even the manual is common for QUAD 22 Control Unit and QUAD II amplifier, photographic presentation begins with a few shots of full audio system designed for stereo reproduction.

After the PS-1 control unit, I became the proud owner of 100Bis tube amplifier. This amplifier and PS-1 control unit constitute  an electroacoustic set. More specifically, the set includes two such amplifiers and one control unit. Amplifier, which is presented below is of excellent condition. The only apparent damage (except for scratches resulting mainly from improper storage) is a small loss of the plastic shield, which acts as an amplifier decorative front panel.
