Abbas Audio RIAA valve phono stage EL84 EF86 EZ80 81 / Audio Note / Croft Excellent beautifully constructed (August 2021) valve phono stage made by classically trained musician in Kyiv. Rated 230v. Good for UK, Abbas confirmed, and so it is, I have three of his preamp units. Potent dynamics, wide soundstage, air and natural rich tone allows magical depth of natural sound LP playback. After 10 years using a Glenn Croft (x3) valve phono stage with off-board dual mono 500kva PSU, I found the Abbas delivers appreciably more, begging the question, how much more could one hear from LPs? I have two units. I will retain one with dual voltage transformer. This second should go to a new home. EF86 input, passive RC RIAA with Siemens PIO capacitors, output with choke-loaded EL84s, Use either EZ80 or EZ81 rectifier (Mullard EZ80 supplied as well as original USSR made valve) Audionote tantalum non magnetic resistors in the EF86 anode and in the correction circuit. Black gate and audio note capacitors. Vintage Siemens MP coupling capacitors. Black gate VK in the cathode. Standard specs: Gain: 42db at 1kHz flatness 0.2dB 47k input load The preamplifier has a very high overload capacity. The RIAA amp is dead quiet using 104dB efficient loudspeakers. The amplifier is listed elsewhere. Local collection or could send via Courier, Ebay shipping programme insured, in original shipping box and materials, with valves removed from RIAA and packed separately inside carton. ADDED: 23 August - (x4) Abbas supplied valve dampers colour red oxide included in sale (not the white items appearing in some of the listed images) Manufacturer’s statement: This product is not for connoisseurs of cold, thin sound, taken as a standard in high-end industrie. This device will not give you a chance for dispassionate contemplation. You will be forcibly involved in the process of perceiving music. There is no sterile cleanliness and whiteness, predictability and boredom, characteristic of modern electronics, developed in the dull office of a famous company. Here it’s the other way around. A riot of colors, mood contrasts and unexpected twists. A violin playing a cantilena will amaze with its tenderness and ability to sing, while aggressive rock will impress with strength and energy. The tone will be wide and powerful, and trebles are natural, without ringing and ostentatious brilliance. You will hear the voice of another era, the golden period of valve technology. In those days, engineers knew a lot more about what music was for. It is needed in order to excite hearts and make us more spiritual. We did not just go back in time, we tried to take the best of the past and combine it with some of the latest advances in technology, such as superb modern audio note resistors and black gate capacitors, alongside vintage Allen Bradley and Telefunken components. Low distortion, good detail clarity, articulate bass, short signal path, no negative feedback, powerful output stage. As usual, there are non-standard solutions that are specific only to our product. These are special boards covered with gold and without a mask. Violin varnish coating, special preparation of electronic parts — resistors and capacitors. Handmade wire made using vintage copper, vintage Kester solder was used to assemble. Please pay attention! We use wires, resistors and capacitors only in accordance with the direction of best sound. In the audio world, few people care about this. This way of working takes much more time. It is all more like a building of musical instruments than electronics manufacturing. Each device has individual features, unlike a faceless conveyor product. That is our approach.
