Sigma Elektronik-Fiyat listesi-Plak Okuyucular-Pikaplar. Carmen SE 47. Carmen SE 47 Amplifier Here's a shot of my latest project.
It's a Single-ended 47 Pentode amp. I chose the copper chassis and mahogany side panels to make something a little different from my regular amps. I think it looks pretty good. It sounds great :-) The amp is convertible between pentode and triode mode by flipping the toggle switches beside each 47 output tube. The power transformer provides 295-0-295 VAC at 100mA, about 320VAC with no load from each half Rectification is with a pair of 816 mercury vapor diodes. The switches on the front panel are, left to right, power switches (manual delay for the MV tubes), feedback selector, meter selector switch (the meter is out of the circuit in the center position and it measures current through the 47s in the left or right position), volume control and input selector. This amp had so many controls that I felt I needed to label them somehow. The copper was a bit difficult to work with because it's so soft. Vintage Audio Components at Phonopreamps.com.

This months tube is a very special type with some extraordinary properties, the 6HS5. This is a quite 'modern' tube, developed in the 1960ies. It's application was high voltage regulation for the acceleration voltage of color TV picture tubes. It was intended as a pulse type high voltage regulator. Collection: Projects. Phonopreamps.com Home Page. DAC Final. Back to www.audiodesignguide.com DAC Final test June 16 st , 2006 Several years ago I started a 'long-term' project to explore the world of Digital to Analogue Conversion.
Right now, after many years and a lot of testing with different technologies (see the projects DAC 1.0 to DAC 4.0 on this website and my paper published on audioXpress magazine may 2001) I imagine to have a broad vision of the sonic performance related to this critical component of the audio chain. Now it's time to explore the new components available on the market with 24bit 96-196KHz and the ASRC (Stereo Asynchronous Sample Rate Converter) that together promise an extreme sonic performances. The test will be on the best DAC chips that are the top products of 4 different manufactures: Analog Device, Wolfson, Burr-Brown and Cirrus/Crystal.
The main problem using these new DAC chips is the small outline packages (28 pin SSOP or 28pin SOIC). Le monstre.

The reason for this page is to present my findings on single fullrange-driver speakers. What is a single full-range driver speaker? Full-range single driver speakers attempt to cover the entire audible frequency spectrum using only one driver unit. Dick Olsher has a nice write up called Single Driver Ecstasy that explains much about the magic of full range and wide range drivers, especially those that cover the mid range spectrum. Not all of the drivers or speakers featured on these pages are true "single driver full-range" speakers.

Zigmahornet Speakers with Fostex FE103E. Zigmahornets with Fostex FE103E / FE103En I first came across the Zigmahornets in a 6moons audio review.
The original Zigmahornet speakers were designed for use with the Fostex FE103 driver, but many have also reported good results with the Fostex FE103En fullrange speaker driver and the Fostex FE103E which is what I used. Enclosure plans for the Zigmahornet are available from the planet 10 box plan library and are shown below.

The results are obtained by playing and recording test signals passed through the tested audio path by means of frequency analysis algorithms. A more common mark is also provided for those unfamiliar with measured technical parameters. A new version is the result of two years of development by best experts in digital audio.
