The 300B-XLS will reproduce the required loudness with more ease than the standard 300B. The result is a more transparent sound picture at low or medium volume, while at higher volume, the dynamics of the original recording will stay unaffected. The 300B-XLS will bias in any amplifier the same way as the original WE300B.

Procedure The very first thing I needed to have was the schematics. Audio transformers optimised for all applications. "Out of the box, the amp is so good I can't

Psvane 300B TII Series (Matched Pair) This should allow auditioning of the KR tube operating at regular 300B operating stress levels. But the output power would be about the same, according to what I see on the KR data sheet. To get more power: The XLS tube's plate resistance, transconductance and gain (mu) are real close to the WE book values. EML 300B. Emission Labs. Regular price €339.00. EML 274B MESH.

It is a stellar performer that will provide you with the ultimate in clarity without sacrificing the music in its quest. EML XLS, Czech Republic, is a very rugged design and is exceptionally reliable and has a reputation for an ultra long lifespan. Just a terrific fit for my amplifier and the sound quality is superb. Elrog 300b, German, another superb sound quality 300b. Unfortunately I had the early production versions and had three tube failures.

The result is the "Fatboy" 300B amp - named as such because, like me, it is a tad overweight. Amp Design 300B SE Schematic: I am using the Sophia branded TJ perforated plate 300Bs. To my ears and those of my friends, these are as good as new production 300Bs get but not as satisfying as the 845.

300B mods (back to top) Mail from an experienced 300B builder (and my comments in red) #1) The most important (sonically) capacitor is the 300B Cathode capacitor and the Powersupply capacitor for the 300B Stage, because they are such large values and electrolytics, even Black gates are quite bad.

This amp would allow testing of even EML and KR high-current 320-style XLS … "Fatboy" 300B push-pull amp. The last few amplifiers that I've designed used pentodes and lots of NFB to get low distortion. So I decided to go to the other extreme: how low distortion could I achieve with no negative feedback of any kind. The result is the "Fatboy" 300B amp - named as such because, like me, it is a tad overweight. Amp Design 300B SE Schematic: I am using the Sophia branded TJ perforated plate 300Bs.

As a thank you for the 300B amplifier schematics, Stamou has shared with us his implementation of the 300B single-ended (SE) tube amplifier schematic by J.C. Morrison. I have assisted by translating, fromating and presenting his DIY 300B triode amplifier The texts about the 300B tubes and 300B circuit diagrams are made by Mr. Leven. At 4tubes.com you can not buy 300B tubes, or other materials. Here you only find information about the tubes 300B, 300B-XLS, 1605, KT88, KT120, EL34, 211, about the Lundhal transformers, Mundorf capacitors, Yamamoto Soundcraft parts, and of course the tube schematics that are used. Re: 300B Amplifier Schematic October 5th, 2019, 12:11 pm To follow up later in the morning, just remembering you are using the 300B amp in a midbass horn (100-500 Hz), I believe I had slightly better results using a PP2A3 amp than a set amp on my setup. Nov 7, 2016 - Stamou Tasos outlines the design and construction of a 300B single-ended triode (SET) tube amplifier following a single-ended (SE) tube amplifier schematic by J.C. Morrison.

I do own a pair KR Audio 300b as well. The Genalex Gold Lion 300b doesn't have the same sheer rock solid sovereignty like the KR. She sounds a little more flourish less sober and less detailed compared to the KR but offers a very wide soundstage nonetheless and a very good tonality over the complete spectrum and is or course detailed.

This amp is the quintessential triode amp. It just does its job, period. It is honest and accurate and sweet and will drive a surprising number of commercial speakers to acceptable levels.
