"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 The considerably more expensive Svetlana 300B turned in a much more evenhanded and refined performance than either VA or Sovtek. However, leaving aside concerns about reliability and availability of the Svetlana 300B, I got even better sound from the "Billie" Kits using some new Chinese made 300B's also supplied by DIY Hi-Fi Supply.

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. 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. The single-ended 300B tube amplifier circuit will deliver about 8 Watts and is well suited for use with high sensitivity speakers. The design you have there is a classic 300B design using a cascaded 6SN7 driver. It's been around for donkeys years in various guises a-la JE Labs, Walton Audio, Sun Audio etc.

The specifications for the 320B XLS meanwhile suggest a different beast that comes into its own at non-standard settings. Unless your amp was specifically optimized for it, you're better off with the 300BXLS. The 320's distortion specs reduce as the tube is made to work harder but traditional 300B amps won't provide the necessary conditions.

Bias of the 300B-XLS. The 300B-XLS will bias in any amplifier the same way as the original WE300B. Here are some schematics with the 300B-XLS tubes are listed. This tube behaves like any normal 300B tube, if biased as such.

Quoted from 6moons.com 'Rated at 95dB, the Colotube 10wpc amplifiers had an easy job of driving these speaker and did so very well. With just three tubes and avoiding the almost ubiquitous small driver tube by favoring a full-swing 20A instead—proving fearless of higher gain and voltages—the Colotube mono's sounded liberated from the tubular confinement often praised as tube sound.

NO. Procedure The very first thing I needed to have was the schematics. Audio transformers optimised for all applications.

almost twice the power). 300B-mesh. 300B-XLS. 520B ® EMISSIONLABS is a registered 302B / 32B or the Emission Labs XLS tubes, which provide even more power than the standard 300B (e.g. more than 40W with the 32B).

So I designed and built this: There is an article in audioXpress magazine (May, 2009) I put together on this, so I won't post all the details about the design and construction - please buy the magazine! This is our DIY tube amplifier with famous Western Electric 300B triodes and Siemens C3g pentodes (here strapped in triode mode). It is a parallel single end 2010-09-29 The 300B-XLS will reproduce the required loudness with more ease than the standard 300B.

Triode curves for the 829B - Thanks to Paul LeClercq - Tube #1 (XLS) (PDF), tube "Valves and Electron Tubes", indexed 67-page tube manual (BIG, full- color, file) - Nice 1939 full data sheet on the 300A and 300B- Thanks t

To my ears and those of my friends, these are as good as new production 300Bs get but not as satisfying as the 845. The regulated power supplies make this amplifier fairly easy to adapt for other tubes.
