Welcome to over posts and to over 50 articles on amplifiers, tube-based preamps, crossovers, headphone amplifiers, single-ended amplifiers, push-pull amplifiers, Circlotron circuit design, hybrid amplifiers, cascode circuits, White cathode followers, grounded-cathode amplifiers, tube series regulators and shunt regulators, the Aikido amplifier, tranformer coupling, DACs and tubes � and hundreds of vacuum tube circuits that use 6SN7s to B s, all explained in careful detail.
Bipole Electrostatic Speaker. Blog Posts on GlassWare Products. Attn-2 Stereo Stepped Attenuator Stepped attenuators deliver decisive clicks and precise attenuation. Sadly, they are never cheap�well, at least the high-quality ones are never cheap, as the sealed switches with hard-gold contacts are expensive in the extreme. Thus, the need to be frugal with the number of switches used.
The new Attn-2 uses two rotary switches, one 6-position switch on the left for fine decrements of 1dB and one positon switch on the right for coarse 6dB decrements, which allows for 0dB to dB in 1dB steps for two channels Well, that is not what I did.
Why not? So, instead I created a 12Vac power supply that delivers a regulated PS High-Voltage Power Supply The PS makes building a tube power amplifier much easier, as it provides three output voltages taps: one for the output tubes, one for the driver stage, and one for the input stage Recently, low-voltage bipolar power supply kits are all the rage, so I decided to reintroduce the design.
Thus, the name change My existing two other 12Vac designs are big hits, as the volt AC sidesteps the wise fear of high-voltage. The most interesting part of the design is the on-broad power supply. How do you get Vdc out 12Vac? A voltage octupler circuit, which uses many rectifiers and capacitors to build up the raw DC voltage of about Vdc Both PCBs are 3. New CCDA Mono Noval PCB In post , I wrote about my urge to build a truly minimalist line-stage amplifier, which would take advantage of my PS power supply that offers a regulated high-voltage and two entirely separate low-voltage outputs.
Friends and readers had been telling me for years that giving each channel its own heater power supply improved the resulting sound Aikido Novel Stereo Rev. The most important change is the return to the option of building an Aikido push-pull headphone amplifier In fact, it holds two LV-Reg regulated power supplies.
Well, sometimes, you need two. But more importantly, this new PCB can be configured configured as a bipolar power supply for use with solid-state circuits. The odd fact about three-pin IC voltage regulators is that no one makes a great negative voltage regulator or, put differently, no one makes as good a negative regulator as the LD is as a positive regulator.
So, two positive regulators are used instead of the usual negative-positive regulator paring. How is that possible? How do you get a negative regulator out a positive one? Where the Unbalancer circuit accepts a balanced input signal and delivers an unbalanced single-ended output, the Balancer converts an unbalanced input signal into a balanced pair of output signals New Product: Atten-2 A stepped attenuator overcomes the liabilities of the conventional potentiometer-based volume control Like the new Rev E.
In addition, each channel's heater power supply connections are separate. And the new PCB is half an inch shorter Although the circuit remains the same, two Aikido gain stages with passive RIAA equalization in between, I felt that the new boards were different enough from the PH-1 to warrant a new name, PH Aikido Octal Stereo Rev.
E A small divide exists in the world of tubes: noval and octals. I know a few absolute partisans, who will not tolerate the other type of tubes. Mostly, these are old guys who love octal tubes and view novals being a steppingstone to transistors. In contrast, I have met many tube fanciers who have only owned noval-based audio gear and have shied away from octals due the high prices of NOS 6SN7 tubes This new power supply is quite similar to the old PS Aikido Noval Rev.
New PS Kit for Tube Equipment: PS For two decades now, I have been told by audiophiles whose ears I trust that giving each channel its own separate heater power supply improves the sound, specifically, the stereo imaging. The culprit might be the heater-to-cathode capacitance, which could provide a path for inter-channel mixing of signals The Aikido 12Vac is one of my most popular kits. Two reasons: you power it with a 12Vac wallwart and yet all the Aikido Mojo obtains.
Well, my expectation is that this new ACF 12Vac will prove even more popular. No gain. No gain, no pain. Most CD players and DACs offer more than enough output to drive most amplifiers beyond full output and into square waves. So why add extra gain? This is good news for me, as this is the power-supply that I use most in my own projects, as it small, but powerful.
That is a lot of juice It is now half an inch shorter. I wanted the PCB to be able to fit in more enclosures. For example, the Hammond extruded enclosure is 8. I have used this extruded box many times before, for example with my 12Vac Aikido PCB, as shown below I own many, say 30, old-school power transformers that offer center-tapped high-voltage secondary and both 5Vac and 6.
They languish. They just aren't suited to modern tube circuits that use both solid-state rectifiers and regulated eater power supplies. I started to write sister PCB, but the 5Y3 tube rectifier made me change my mind. Sometimes a cigar is just a 5Y3, but Bass Hunter Boat For Sale Craigslist Token not this time. Where the PS-Tube-SS was designed for those who wish to build a tube power amplifier, the PS-Tube was designed for those who wish to build a tube-based line stage or phono stage�using a tube-rectifier-based power supply Unbalancer Two Like the original Unbalancer, the Unbalancer-Two circuit accepts a balanced input signal and delivers an unbalanced, single-ended output.
Besides performing the conversion from balanced to unbalanced, the circuit provides a little gain usually, about 1. PS-Tube-SS It's a familiar problem: you would like to build a tube power amplifier, but you are daunted by the thought of having to deal with the high-voltage power supply.
Select-CM You already know that the standard Select-C switch allows you to switch between output coupling capacitors�in stereo. The new Select-CM allows you to do this in mono.
In other words, this is a special capacitor selector switch that is designed to work within dual-mono setups, either line-stage or power amplifiers. Aikido Phono preamp, Rev. B The Aikido PH-1 returns�and yes, it has been a long, long time.
What is an Aikido PH-1? The Aikido PH-1 is an excellent tube-based phono stage. It holds two Aikido gain stages per channel and uses a passive RIAA equalization network in between the two.
In other words, four Aikido gain stages reside on the PCB. One Aikido PH-1board is all that is needed for stereo phono pre-amplification New Three-Position Tilt Control Few stereo systems off a tone control and the few that do hold a bass and treble control, which seldom prove adequate. Often a recording is not so much deficient in just the lows or the highs, but out of sonic tilt in terms of frequency, much like a photograph that is tilted The PS is a tad bit bigger, being 3.
Where most of the increased PCB space went to is the lager heatsinks. Either a 1. It uses an LM for the positive output and Bass Hunter Boat For Sale Craigslist Quest an LM for the negative output.
Stereo-Mute-Mono Switch Here is something that I have wanted for myself for the longest time; its a rotary switch for phono playback that presents three positions: mono, mute, and stereo It is an All-in-One due to it holding everything, including the power transformer The Tr-PS-1 holds its own power transformer Tr-PS High-Voltage Power Supply Power supplies, particularly high-voltage power supplies, are often the big stumbling block to a successful completion of a tube-based audio project.
The other half is getting the power transformer. Well, with the new Tr-PS-2 power supply both problems are solved at once, as the Tr-PS-2 holds its own power transformer Cathode-Coupled Amplifier I have been writing about the cathode-coupled amplifier for a long time now and many have asked for a PCB based on this circuit. Well, the wait is over. Back in blog number , I revealed a clever cathode-coupled-amplifier variation that greatly enhanced the circuit's PSRR What another power supply?
Yes, indeed, as it fills a gap. The PS was designed for those who need a high-voltage power supply with two sets of regulated low-voltage power supplies usually for powering heaters. Why would anyone need two low-voltage regulators? More than you might imagine Some just prefer the sound from octal tubes, such as the famous 6SN7, so its absence was felt, myself included The boards are small, being only 4in by 4in, but pack quite a wallop due to the large-valued capacitors used.
Two RC-based pi filters smooth the bipolar DC outputs
