Like the new Rev E. 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: 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 power supply is super simple: This new power supply is quite similar to the old PS The PCB color is now red, but the real difference is found in two major changes: 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. Well, my expectation is that this new ACF 12Vac will prove even more popular.
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.
I started to write sister PCB, but the 5Y3 tube rectifier made me change my mind. Sometimes a cigar is just a 5Y3, but 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.Sep 07, · Get up to the minute breaking political news and in-depth analysis on grupobittia.com The Nightmare before Christmas The Plot Halloweentown is a fantasy land overflowing with ghosts, vampires, and witches.
