12AX7-ECC83-Tube-Preamp.jpg12AX7 / ECC83 Tube Preamp2451 viewsHi, I have built preamp with double triode 12AX7 from your web site.

The sound of this preamp is very very nice, detailed and realistic.

A work in progress. This is only an assemblage of parts so far with nothing bolted together, but it gives sort of a preview of the finished project. The chassis will be painted black wrinkle much like the transformer covers in the back. The driver tubes are 12SN7s and 6SL7s

6p45s_push-pull_class-A_amplifier.jpg6p45s tube push-pull class-A amplifier1535 viewsHello, my name is Vitaly Gorbachevsky from Russia. In this photograph is a push-pull class-A tube amplifier that I built. The maximum output power is about 34W per channel. The vacuum tubes used are 6p45s tubes in the output stage and a and longtail 6n23p driver tube. The name for this tube amplifier project is the SILVER GLOW.

Here is a link to an article that shows how the amplifier was constructed. http://people.overclockers.ru/primrose/record2/. Note that the the text is in Russian however that are several pictures in it that will be interesting.

6EM7-Single-Ended-Triode-Amp.jpg6EM7 Single-Ended Triode (SET) Amplifier72 views"This amplifier is based on a tube intended to drive the vertical deflection circuits in larger televisions, the 6EM7. It has two dissimilar triodes in one envelope. One is a high gain, low power unit intended as an amplifier or oscillator, and the other is a higher power unit intended to drive the magnetic deflection coils on the back of a CRT. At audio frequencies the combination is just what we need to build a nice little audio amplifier. One tube per channel. And there are many thousands of these tubes and tubes like them readily available today."

6CY7-Stereo-Amplifier.jpg
6CY7-Stereo-Amplifier.jpg6CY7 Stereo Amplifier97 views"This is a nice little low power stereo amp (1.3W/channel) based on the 6CY7 tube. The amp uses a Hammond power transformer and chokes and a pair of Edcor XSE10-8-5K output transformers. I have to say that it sounds really nice. There is just something about triode SE amps that nothing can beat. The peak clean power output is 1.3 watts RMS per channel (as determined from watching an oscilloscope). The 3dB frequency response is ≈48 Hz to 30 KHz."

Class-D-SureElectronics-Amp.jpg
Class-D-SureElectronics-Amp.jpgClass-D Sure-Electronics Amplifier400 viewsThis is my first DIY Class-D amplifier. The amp is based on a $30 Sure-electronics module. The amplifier modules requires only a 30VDC high current power supply because into 4 ohm it can produce 100Wpc. The enclosure is an off the shelf 2U 19” rack mount type. The power supply has an 18-0-18V, 9A toroidal transformer. A 10A rec bridge, some snubbing caps and 30,000 uF of stage caps make up the power supply. Two selectable inputs provide direct connection to the amp module or connection via an Alp pot and 4 Oz brass knob. Very crisp sounding with good detail... See the forum thread Class D 100W power amp for more information.
