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.

The amplifier belongs to the group of devices produced in such a small number of copies that it's creator is hardly called a manufacturer. The amplifier does not have any notes or signs and to find information about the person who built it is almost impossible. It turns out that it is the product of (a term a bit exaggerated) manufacturer named ARG. The ARG "company" it is probably one person, Mr. Eugene Kremiński from Lviv. I have not found any corporate website or the official list of ARG products. The only source of information are online "notes" of a few users, or friends of the amplifier's builder. I decided to put the amplifier in the gallery because of its quite unique schematic configuration. It is a circlotron .

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.

Although the Ayon Orion tube amplifier is already presented in the TRIODA Web Gallery, but because of the fact that I had the opportunity to see the interior of the same amplifier, but of very different interior, I decided to share a set of photos with other details of this interesting device.

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.

I would like to present some photos of a very interesting STA25 Renaissance tube amplifier manufactured by Woodside Electronics. It's basically a modernized version of the amplifier produced by Radford. The main difference relates to the regulation of quiescent current of output tubes. The amplifier is characterized by interesting and controversial design line. Like previous Radford products, it raises big emotions - from admiration to total criticism.

BAT VK-150S is a powerful tube monoblock offering considerable output power of 150W/4Ω. Let no one be fooled by the "SE" symbol in the amplifier name. It is not Single Ended circuit configuration but only a special version of the device (Special Edition). Unfortunately, I do not know the details that distinguish ordinary amplifier versions of the SE version. Based on expert mentions in the press, the details are very important but supposedly secret .
