These were made for the military, as you can see from the sword signs on the back side of the tube. Ask our experts To ask our Hanna experts a question please include your contact details. In other words, I want to turn this: I went ahead and added -channel RGB to my answer. They are often used in guitar amplification and include versions of the popular 12AX7, EL84, EL34, many of the vacuum-tube amplifiers in modern production are factory-fitted with Sovtek valves, due to their low noise performance and lower prices than other makes. I'm still letting it break in, but so far it's wonderful, better than it has the right to be for so little money (I bought 6 829B's, 4 RCA's and two Mullards, for a total of about what a single Sovtek 2A3 would cost). SOVTEK 2A3 2A3, direct heated triode with oxide cathode is used for low frequency power amplification in output stages of amplifiers.
When you intent to get the maximum out of a 300B, and operate this tube at the limits of safe operation, it is a better idea to use the 300B-XLS in such a case. Resistance Coupled Amplifier Charts: It can produce 17 W output in Class AB1 in push—pull configuration. All these links open in a new browser window so that you can return quickly to this page without having to reload. The sound quality is seriously improved from any other tube manufacturer when used in this BluRay Universal deck. You will get a bit more power out of 2A3/6B4 tubes by going to 5000 ohms plate-to-plate.
The best part is that you can get a quad matched pair for about $50.
Though 40 Watt is possible, this is a peak value only, and no normal working point. The 2A3 amplifier schematic above uses the parafeed topology with plate choke, parafeed capacitor and parafeed output transformer. RCA was likely the developer, since it had assigned a development number of “A4273B”. much gain when play Classic.Power is around 5W rms at 3% with Sovtek 2A3 and clear sound.2A3 EH gold is a little bit expensive than 2A3 Sovtek and Sovtek 2A3 sound is much better than 2A3EH gold.even 2A3C is good sound to get and very clear and powerful. Dec 19, 2019 - This Japanese single-ended, vacuum tube amplifier can be purchased in ‘kit’ form or fully assembled. Holding my breath hoping my amp didn't go up in smoke, I turned on the switch to the system (you know what I mean, you've been there before). The sound was congested with a spatial constriction and a dull and sluggish presentation. Feb 6, 2019 - This Japanese single-ended, vacuum tube amplifier can be purchased in ‘kit’ form or fully assembled.
It‟s a solid tube, but for the current 6V6 tube production, I have tried some Tung Sol reissue, and they do sound really close to the old NOS 6V6 tubes. Before you use the A and B versions, check the filament current requirements to ensure they don't exceed the original design specs for the 2A3.
I put Sovtek 2a3's in and they measure 2.5v filament but when I put in 300b's they measure 5v filament. The low end is better than the chinese KT but it's a trade off because the sovteks have the seemingly patented brittle high end going on so these are a better match for humbuckers, single coils beware!

Unbeatable prices on thousands of guaranteed vacuum tubes for sale, vintage NOS hi-fi audio tubes, radio tubes, ham and industrial ready to ship. Unfortunately I had to sell it at a pawn shop in florida so I could get out of that place. Modulation is a broad category which also includes phase shifting, vibrato, chorus and more. A legacy of great sound at great price - just $599 - Now shipping with Sovtek monoplate 2A3s The Paramour kit is a pair of single ended parafeed 2A3 mono-blocks.
I chose the 2A3 directly heated triode power tube to implement the Loftin-White circuit. The 12AU7 and its variants are a miniature nine-pin (B9A base) medium-gain dual triode vacuum tube. It belongs to a large family of dual triode vacuum tubes which share the same pinout (RETMA 9A). Driver ECC88 and 6N1P are more clear and not too much bass but sound more musical.
Modelled after the vintage RCA 6L6GC "blackplate," the Sovtek 6L6WXT+ features larger plate dimensions and improved grid structure for increased power handling capabilities. We design and manufacture our tubes, engineered for demanding high fidelity, reliability and overall warmth.
This Japanese single-ended, vacuum tube amplifier can be purchased in ‘kit’ form or fully assembled. Features a conical, rugged tip that can be directly inserted into moist or soft soil. As of [update] a slightly modified version of the 6P14P was manufactured in Russia for Sovtek. Sovtek 2A3 is more cheap than any kind of new 2A3 but sound is very clear than 2A3EH and 2A3C.feel like minor distortion than other new 2A3.I'm using 3.5K out inpedance for plate. I'd like to try out the so-called 2.5 volt 300B, but I have dozens of real US made 2A3's and don't want to spend the money on the 2.5 volt 300B's.
hhi Be the first to know when we have news, discounts, special offers and promotions. The 2a3 tube, which produces around 5 watts, consists of a single-ended triode amplifier utilized mainly for output stages of audio power amplifiers. Audio Note Conquest Schematic.pdf schematics and service manuals - download for free! Here you'll find manufacturers' data sheets and curves for many popular (and some not so popular ) electronic valve types.
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. Here is a longer dissertation of the amplifier theory that I wrote up:It is an integrated amplifier with a passive input stage, putting out 6 watts per channel. The Silver Night Stereo range can reproduce subtleties and nuances in music that can not be found in other amps of this price. Feb 6, 2019 - This Japanese single-ended, vacuum tube amplifier can be purchased in 'kit' form or fully assembled. I am the original owner and I am rating this amp as an 8/10, but I think it could pass for a 9/10.
5V (for 2A3) render this idea as very bad until we realize that there is an octal equivalent of 2A3 called 6B4G (Russian name is 6C4C). This is a model that takes into account the physics of the filament, something I call composite triode model. In this project, the 2A3 power tube runs at a 60-mA plate current with no signal applied and has a 410-V plate voltage. The Silver Night Parallel single ended amplifier comes with either Sovtek or Electro Harmonix 2A3's but can also be made with 300B or PX25 tubes upon request. The 2A3 vacuum tube is a power triode capable of outputting 3.5 W in a single-ended Class A configuration. Rejoined several times by Minna — now matronly, charmless, and censorious — the Huldigungdmarsch affair had soured their marriage beyond repair at a time when Wagnerfeeling the middle-aged itch, was looking elsewhere.
