12ax7 headphone amplifier schematics

My Opamp based balanced preamplifier sounds good, it sounds very clean, quiet, accurate and very high resolution. But at the same time I found it a bit plain. So I think it is time for me to try something sweet, warm, and "musical". Even order harmonics sound as musical chords notably octaveswhich subjectively makes the sound "richer". Odd order harmonics sound less pleasant.

The circuit diagram of the filter section is shown in Figure 1. It is a completely conventional The circuit has been designed to accommodate all those who dedicate many hours of their lives by An input rectangular signal is differentiated and short impulses are formed from its edges A dual DC motor controller that utilizes an H-bridge controller chip. As well as the basic Before attempting to build the control circuit, it is recommended that the function of each part This project involves the construction of a low-cost curve tracer that is suitable for testing a This preamplifier was designed to cope with CD players, tuners, tape recorders etc.

This simple circuit tests speakers, microphones, transformers and voltage. A very simple controller circuit, with fairly smart performance! The example circuit is for an automatic animal feeder.

When the animal pushes the switch the Posted on Feb 5, Under: Repository-circuits. Would it be better for me to use this circuit or design a circuit from scratch If I did decide to use this circuit, would it be ok if I used a V power transformer or would I have to use a V transformer that is in the schematic. Also, would it be better to not use an output transformer like in the schematic Here is a schematic of the Leslie power amp that I am driving: Please keep in mind that the Leslie was designed to go with this preamp schematic.

I am open to any and all suggestions. And wheter or not to use a solid state or tube rectifier. Here is another schematic of an older Hammond AO preamp. It uses a V transformer to get the V and V supplies, but it uses a 6X5 rectifier instead of a 6X4. Visit page. Related Circuits Linear Resistance Meter. Liquid detector water sensor circuit.

Lithium Ion charger circuit using LM Logic Probe for Tri-state Logics. Long-Range IR Transmitter. New Circuits Ultrasonic distance finder circuit. The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is Simple Metal detector circuit with CD Sometimes the precious metals are hidden too deep and are not detected except with complicated devices.

In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to Fully automatic watering circuit for flower pots.

Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? Simple deep searching metal detector circuit. The principle behind a metal detector is really very simple.

Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the The sub-harmonic bass generator is a sound producing unit for guitars.

The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound, Echo Depth Sounding Sonar for Boats. In the past the sounding sea bottom measurement was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope.

As soon as the "bullet" reached the bottom, the depth appeared directly from the This Amplifier was designed to have the following specifications: Distortion less than 0. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power A series of LEDs serve to alert the gardener when plants need water. The device detects the amount of water in the pot and alerts the grower The best human ear can capture sounds from 20Hz to 20KHz.

There is a lot schematics on the internet, but finding a good one is pretty hard. The world is changing; we're adapting. We realize the change -- which came about unexpectedly on its own -- is an inconvenience, maybe a Check the circuit description below. The output stage of the circuit is a Cathode Follower and is suitable to drive a low impedance amplifier. If you know the specs for the transformer, this is an easy task.

NP-100v12: 12AU7 (ECC82) / IRF510 Headphone Amp

This is a simple class A headphone amp using a 12AX7 running off of 9V. I tried to design this to be as simple as possible while using common parts. For example, this project uses the ubiquitous 1k:8 ohm audio matching transformer as an OT rather than any expensive and hard-to-find tube OT.

Product Discription. From the highly respected UK outfit based in Leicester, this is one amp that most of the media has criminally ignored but is a great, small footprint for the company, at any rate valve-driven device that includes a headphone socket at the front with a neat, two-position, input selector and volume control. Buyers bear all responsibility for all extra charges incurred if any. The 6CH6 gives a crisp low distortion audio output.
