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.

PCL86 electron tube belongs to a group called "TV tubes" - tubes used in TV sets produced in the last tube TV's. In general, the models produced in the late 70's and early 80's of last century were already mixed transistor-tube devices. A classic example of this TV was the "Libra" produced in the Warsaw Television Plant (WZT). With this design sentimental memories bind me, because I belonged to a group called. "assemblers" who, as the name suggests, were involved in assembling these TV's from parts obtained from "Bomis" (younger Internet users have a little search online to find out what it was).

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.

The QUAD II tube amplifier was manufactured by a company with big traditions, as founded by Peter J. Walker in 1936, SP Fidelity Sound Systems, renamed later in the same year to the Acoustical Manufacturing Co. Ltd. The company was initially located in London, but after a bombing in 1941, was moved to Huntington. The name "Ouad" is an acronym for "Quality Unit Amplifier Domestic" and I must admit that the equipment bearing this name deserve to be called a high-quality audio equipment. The name "QUAD", used for many years only to manufactured products became so known in the market that in 1983 the company changed its name to QUAD Electroacoustics Ltd.

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.

This stereo tube preamplifier was produced by JJ Electronic. It is characterized by interesting colors reminiscent me Lotus cars competing in Formula 1 - a mixture of black and gold . I am a fan of Lotus team, so it's no surprise that I like this color combination. The only problem is the inability to take a picture in a way that surrounding objects are not reflected in the golden housing. It is presumed that one of the purposes underlying the company was to promote electron tubes produced by them (the preamplifier has as many as 8 tubes). This has been only partially successfull. Preamplifier certainly served the brand, but rather as an independent audio device, than the device equipped with tubes with JJ logo. In some copies, which I inspected I found tubes from other manufacturers.

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.

PHAST's audio equipment is very well known to our home audiophiles. PHAST name is an acronym for Phase Style, which in 1998 replaced the "Phase" - original name of the company, founded in 1988 in Lviv. Phast's current offer is not too large, but interesting. Includes both power amplifiers, integrated amplifiers and preamplifiers. It is difficult to collect reliable information on device models offered over the years in each group. On the company's website there are presented details only for the latest equipment, and some produced in small quantities and are no longer offered . This report is dedicated to the audio set which consists of two monoblocks based on the famous "devil" output tubes and remote-controlled preamplifier.

Not everyone likes the design of the amplifier. This is not surprising. Aesthetic values are not universal - this is what impresses some, others may not like. As for me, I have mixed feelings. I think that if the Designer was consistent and showed also the output transformers this amplifier would look nicer. But, as I wrote, it's just my subjective opinion.
