About Vacuum Tubes 
      A reading rehearsal from this site: »The history of the vacuum tube dates
back to the 19th century, when Thomas Edison first noticed the reaction
between a vacuum and an incandescent lamp. Later, inventors discovered
how to use vacuums to transfer sound on radios and then again on
televisions. Modern day technology has nearly made vacuum tubes
obsolete and it’s evident that the use of the tubes won’t continue into
the future. Collectors of antique radios and televisions find it
difficult to find replacement tubes for their older models. Consider
the links below as resources to help you in your search for information
all about vacuum tubes. ....« more about please click link.

       DIY - Do It Yourself -
was bedeutet dieses Wort? 
Mach es doch einfach selbst. Trau dich. Nichts weiter. 
Viele Dinge kann man wirklich auch selber machen, denn mittlerweile
gibt es genug Quellen im Internet die wirklich wertvolle Informationen
liefern, so z.B. zum Selbstbau einer hochwertigen Verstärkers,
Vorverstärkers, Lautsprecherboxen, usw.. Die DIY-Gemeinde wächst
ständig, nicht nur in den USA. Auch in Europa gibt es durch die
Aktivitäten einiger selbstloser DIYer zunehmend Zuspruch. Mein Beitrag
dazu soll dazu dienen, mein Wissen zu verbreiten, ohne dass jemand
dafür zahlen muss. Ich hoffe es gelingt.

The page describes the construction of a 120W@8ohm audio amplifier,
that has been getting lots of good critics. |

Tubes web site is dedicated to the distribution of informations about
Japanese D.I.Y. audio projects, including: tubes amplifiers, exotic

have such an interest for Japanese custom audio equipment ? The reason
is quite simple, nobody in America and Europe seems to cover this
fascinating world of Asian Ultra-Fi audio art.

       Our small,
independent firm was come into existence in 1979 to produce custom
electric devices (primarily audio amps). In the absence and bad quality
existed on polish market devices, cause that interest of small
manufactured hardware was rising. We decide to do something for that
music market.

       The Class-A Amplifier Site
       
      This site is primarily dedicated to the
Class-A amplifier designed by John Linsley Hood, which was originally
published in Wireless World in April 1969 (with a postscript in
December 1970) and later updated in Electronics World in September
1996. However, other Class-A design articles by Jean Hiraga, James
Sugden, Stan Curtis and L Nelson-Jones have been added, along with some
more JLH circuits. Schematics for other Class-A amplifiers and for
three classic Class-B commercial amplifiers, the NAD3020, the Cyrus 1
and the Sugden A48-II, have been included for reference. |

      Multisine 
The program Multisine is an audio signal generator. All signals are
calculated offline. After the calculation it is possible to store the
data in a .wav file or playback data with your soundcard. The
application is written in C++ and uses the VCL library and Win Api
calls.
