- JJ TESLA has been known for
years for its involvement in valve audio.. Have a look on our new section on this serious
manufacturer.
- 'Cleaning Brushes for
Tube Sockets' is about to become an MTZ audio 'best-buy' product. If you operate a
valve amplifier it might be a good idea to have a close look..
- Also if you like making your
own DIY projects and using a soldering iron, our ' Felder' high quality solder is
something more than a good choice. If you contact us we will be happy to give you more
than one reasons to give up typical 'amateur' solder and enhance all your critical 'earth'
connections..
An improvement of several
dozens of milliohms might seem unimportant to you..
But every time your power
supply rectifier diodes switch on to pour several Amperes to your filter capacitors (and
from there to your speakers), you will not only measure the difference in voltage
regulation but hear it as well !
There are dozens of good
amplifier schematics ensuring high power and minimal harmonic distortion.. yet none will
deliver an exceptional damping factor when you are done implementing it if you have not
gained an expertise in making adequate ground lines. Soldering is an art itself..
Release Date : September the

After a short break for summer
holidays we are back ready to launch our top floor standing two-way speaker project, ARCOS
X. Listening sessions as well as fine tuning have already begun.

understood that most software on low frequency speaker simulation ignore mutual acoustic
coupling between multiple woofer drivers as well as that between driver and port, we are
ready to include this feature in our LFA software..We expect to launch new version 5.5 on
December..

Socket Brushes are distributed in Japan by Triode Corp. www.triode.co.jp
