Best tube amplifier books audiophile
Members Portal. The audiophile preference for tube amps over solid state is based more on emotion than on science. Skeptoid Podcast October 21, Podcast transcript Subscribe. Tube amplifiers. Since succeeded by more efficient, miniaturized circuits, tubes still enjoy deep loyalty by musicians and the audio enthusiasts who spend to reproduce their music. Is the ardor for this antique appliance misplaced, with appreciation colored by extraneous associations?

Building a brand new valve amplifier using the RH84 design and off-the-shelf components. A number of recent visitors have registered surprise that we do not have any music playing in our workshop. We do have a small radio, but it seldom gets turned on. I reckoned it was about time to put that right. Valves were largely superseded by solid-state systems from the mids onwards, but have made a real comeback in the past decade or so — particularly amongst audiophiles — as people realise they produce a warmer sound, as well as having great visual appeal.
These days any kind of valve amp attracts a premium price and I thought that building one for myself, daunting prospect though it was, would be a relatively economical route to take. After doing some research it seemed the perfect beginner's project was the RH84 single-ended amplifier. At the time I designed it I was practically penniless There are also two transformers for the power supply: one 6.
In addition there will be a bridge rectifier and smoothing components in the power supply, and this will be covered in a future post. Where he seemed lacking in information was in the use of a toroidal transformer, which is what I had, although on reading up about them it would seem they have a very low or negligible stray field. I imported the images for the transformers and valve bases from PDF data sheets into Inkscape, drew some of the other components and experimented with different arrangements until I was happy.
I then shared my design with Alex Kitic via email, and he seemed to think the layout was OK, which was good news. I was now happy that I had a viable design at least for the audio stage of the amplifier. We would be using a pair of bench power supplies for testing, so the power supply could come later.
Having used the Fostex FE83En full range drivers in my project to build a Portable 12V Sound System we knew they performed well with relatively small amplifiers and so decided to use them again.
The one disadvantage with this coating is that it only seems to be available in black, red or white unless you are prepared to wait for weeks. We got in touch with our Goth side and went for the black. Given our previous experience and the fact that these were passive speakers and therefore a lot simpler, these would be comparatively simple to put together. As is often the case with these blog posts I have embarked upon something completely new to me and somewhat out of my comfort zone.
It is going well so far, but there is some way to go yet. In future posts, I will be sharing the building of the prototype single amplifier, followed by the final version with two of these and a power supply. Finally, fitting this all into an attractive enclosure, with cabling and connectors etc.
WARNING: The circuit designs are shown here for informational purposes only, this is not a tutorial and the designs are not warranted to be safe. Dangerous voltages are involved and you should not work on such designs unless competent and safe to do so! I make it that for a mono amplifier, 3 transformers are require as you are using a seperate ones for the heaters and the HT supply.
A stereo amplifier would therefore require 4 transformers. Not quite the 2 that the parts list stated. Zonko That's correct. R7 27k and R6 k. I schematick is shown R7 27 and R6 Which one is correct?
Dear sir , thank you for your nice project you are sharing with us. I have a question. Can we skip the supply tranformer and use only the fillament one and the output two? Anyway we are using the same voltage with the socket. I am seriously thinking of building this valve amplifier.
Are there any important facts i need to know before i order the spares? How do you get the v dc with this 2x v transformer? The circuit asks for a 2x v trtansformer. Jdev99 volts 2 x v is the RMS voltage on the transformer. Bonzadog the stereo version is on the bench waiting to be tested. Watch this space! Hi Dave, I'm a bit confused about how you would build the power transformer with the two transformers you list.
The seems to be a isolating transformer and can't provided you with the VV. Hi Dave, Awesome project. Even more awesome is that these parts are available from RS.
A couple of things to note about the toroid HT transformer: 1. Mains type toroids can have a primary to secondary coupling up to 20 to 30 KHz, so are effectively full audio bandwidth for any noise coming in on the mains supply. This is compared to a standard EI laminate transformer which has the primary and secondaries in separate sections on the bobbin - coupling there should be 1 KHz at best worst?
Toroids can also produce an audible hum if the mains sine wave is distorted, e;g; by computer switch mode power supplies. By comparison the EI lamination layup gives a nominal gap so the transformer is less susceptible to small amounts of DC in the supply. I would suggest a delayed relay and or other timer for a few seconds turn on. A mechanical relay with snubbing across the contacts gives a nice satisfying clunk : Single ended amplifiers need well smoothed HT supplies, otherwise the ripple will modulate the signal.
Hope this helps. Best, Sue. Sue Interesting information on toroids, I was not aware of these characteristics - thanks for sharing. All the part number links above result in a server error. The part numbers are RS component part numbers. I had to look these up on rs-online. I'm following this project. Looks fun. Hi Dave, This looks like a great project, do you have any idea of what the finished project might cost?

6 Best Tube Amps 2021 Under $500, $400 And $300 (& A Low Priced Live Performance Setup)
This 7 page chapter on valve amps is centred on understanding the operation of the Williamson Ultra Linear Watt valve amp. Valve technology is now redundant and there is no point discussing valve amp designs that fall short of achieving the highest performance for replicating music. Rod Elliott sound. We have collaborated on what we are best able to describe with minimum overlap.

Whatever Happened To The Audiophile?
Linton Weeks. There are still people willing to drop a large chunk of their income on the best audio equipment available, says music professor Mark Katz. You may remember the type: Laid-back in an easy chair, soaking in Rachmaninoff, Reinhardt or the Rolling Stones, enveloped by the very best, primo, top-of-the-line stereo equipment an aficionado could afford. In robot-like, s cadence, the audiophile could rattle off favorite components, which might include an all-tube Premier One power amp by conrad-johnson, a Sota Sapphire turntable, an Ortofon MC cartridge and a pair of Magneplanar speakers. But the audiophile was a symbol of the Golden Age of Audiophonics, a time when certain people worshiped at the altar of expensive high-fidelity, two-channel stereo equipment.
