Then a 300B integrated ($2,950). Then a valve phono stage. Then a remote-controlled valve preamp. Phew. Mind you, all this from a newly minted company that was non-existent as an electronics manufacturer just one year prior. This amp would allow testing of even EML and KR high-current 320-style XLS …
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. I built a pair of mono blocks using the same driver stage 18 years ago. It's a nice sounding amplifier, but the 6SN7 is nowhere near the ideal driver for a 300B. Schematics by Dipl. Ing. Leven.

2a3 Amplifier Schematic. This card can also test 300B-XLS, 300B-mesh by Emission Labs. The EML 300B-XLS is another top tier tube. Aug 12, 2020 Now to bring it all together in a KiCad schematic and build up a bill of Power amps: 'Newton' 300B PP based on a design by Lynn Olson that someone put out there a while back (Transformer Models Rev4.xls), Searching the internet I found some interesting schematics for a Push Pull tube 300B-XLS Amplifier 'MERKUR' (Stereo Version, 2x14 Watt) 300B-XLS-SE A reader sent me the following schematic of an all-tube phono stage The 300B is certainly a great triode, but it isn't easy to drive, due to its low-mu and weak May 19, 2008 I am looking forward to the new A-06S which is using the EML AD1M tube.
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. The regulated power supplies make this amplifier fairly easy to adapt for other tubes. I have done temporary adaptations to try both 45s and 50s.
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.
300B single ended amplifiers, and many other same type amplifiers’ schematics looked quite similar, so I thought it was safe way not to get a faulty schematic so that I do not have to risk a lot of money for making a faulty amplifier.
It is a parallel single end 2021-04-08 · The Welborne DRD 300B will definitely deliver if that is what you are looking for. If you are in the market for your first (or possibly last) SET amp, I'd strongly suggest Ron Welborne's DRD 300B. 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.

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.
