This project born to test the 2A3 tubes and I have created a reference amplifier better than the previous with 300B. The main results should match these items: top sonic performances

New 2A3 PSE by Andrea Ciuffoli - starting in the November 2007 INTRODUCTION. The targets of this project are the following: simple and cheap; hi-end performances; a low distortion to 4-5w on 8 ohm; good damping factor with a Rout < 2 ohm; only 2 stage but no interstage transformer. to be cheap; enough sensibility to be used without a preamp.

2022年9月30日 · Uses Monolith Magnetics nanocrystalline interstage transformers, Electraprint silver output transformers with custom tertiary winding, Wein bridge oscillator circuit for a high-frequency filament supply (~44khz VAC for the 2a3 tubes). Case was custom designed by me in Fusion and then Protocase brought it to life.

2015年1月24日 · In this form the PSE retails for $5999 USD. Triode Lab offers two levels above this, based around either the James or Hashimoto transformers; plus tube upgrades and the aforementioned paint options – basically they’ll customize the build to what the customer wants.

The 2A3 is certainly not the champion of linearity among DHT's however, by general standard, is still very good. You can get 8W with THD within 5% from a PSE easily! Carefully selecting tubes it can be 3% and get a bit more power.

2006年3月9日 · I'm personally going with 2a3 and/or 845 because they're cheap in basic Sovtek or Chinese flavour, and I prefer a thinner more focussed sound than the usual 300b amp. Depends what sonic flavour you like - big and warm or clean and precise. Also speakers, source equipment, room size, listening material etc - what are they?

2015年5月20日 · The PSE is often referred to as a data retrieval machine, we prefer to think that it is not too analytical, but very clean and musical and very transparent. The 2A3 even more so, with 4 more active supply stages to ensure quietness, speed and resolution, the Silver Night is aimed at very efficient speakers and quality, tonality and musicality

A 2A3’s PSE Amplifier (click on images for enlargement) A structurally simple but effective design about a powerful and “cheap” Parallel Single Ended power amplifier is shown in Figs. 1 and 2. As a rule a 2A3’s PSE yields 7-8 Watts in Class A1 operation with 5% of THD and 10 Watts in Class A2 operation with greater distortion.

2019年6月23日 · Séduit par son montage, je me suis mis à rêver d’un PSE 2A3 classe A2 avec 20w à la sortie. Après avoir échangé avec Shucondo et comme il semble favorable à cette réalisation, j’ouvre ce sujet pour clarifier 2-3 questions que j’ai sur ce montage et avoir vos suggestions pour le peaufiner.
