Simple Circuit Single Ended Class-A Valve Power Amplifier base ...
The valve itself having to use a simple circuit enviable each transistor amplifier, but not many projects that a single active component. This design philosophy, as I call minimalism.
Speaking of minimalism, I think this project has all the prerequisites to qualify as such.
This is an amplifier, a built-cu final (compact), which deals signed in a single tube (triode) 6C45Pi. To do so, could more tubes, including 437A, E55L (pentode) and the fantastic and expensive to be used EC8020.
Two lines need for this valve: The EC8020 is an exceptional linearity, high power dissipation and performance worthy of a trasconduttanza triode. All factors, amplifier ideal for a good cu if not for the prohibitive price (on ebay offering easily exceed one thousand dollars!).
6C45Pi even if does not reach the performance of EC8020, leading to the task with dignity. The cost is several orders of magnitude lower and is currently manufactured by Electro Harmonix, and is part of its golden pins sets the most valuable.
The circuit used setup is classic: one end. This choice leads to cheaper power, an output transformer, but all will benefit, at least for my taste, the sound quality.
Diagram-Single-ended Class A power amplifier to 6C45Pi
About Nutrition, the first idea was to use as dressing, a valve, but with an excessive size of the Schottky diode and filter functions are also very good results (Sonic) was obtained.
Not many projects are implemented on the PCB valve, but it is my conviction that offer an ordered structure, the value added to the project’s success.
The provision is as follows: PCB-layout-single-ended Class A power amplifier to 6C45Pi
A basic principle for the design of the board is to avoid a ground contact, so you should avoid as much as possible use in a star structure. Normally, the stars are at the center of the negative of the first filter capacity.
Four resistors are metal film half a watt, the wound enamel coated 220ohm 6W, Panasonic CF electrolytic capacitors low impedance. Alps potentiometer and the diode, as already mentioned, the type Schottky 1.5A 1000V
Both are wrapped TU by the Company to certain ATC Electronix: www.atcelectronix.com/ offers the following features:
Mechanically, the TU are well made, strong, beautiful black caps, we see that the hand of a fan.
The cabinet is birch plywood 10mm polished with wax. I like the fact that the old yellow leaves. The photos have no idea of the size, but it is really small, (TU and TA excluded), only 230 x 60 mm, height 200 mm.
