Well my friends it is time again to say thanks to all of you, who like and ordered my pcbs.

Because i am no developer of electronic circuits but have the knowledge to design pcbs,
i wanted to give something back to the community.

Since i started with my 1st pcb, the Optical-Volume-Control on 15th October 2009,
a small donation from every sold pcb goes to diyaudio.com

Today i am proud to say that your cumulated donation achieve

$ 3104

Keep on having fun with my pcbs and best regards

Oliver

The best sounding I/V resistor

Posted 3rd March 2013 at 09:22 AM by dvb projekt
Updated 3rd March 2013 at 03:17 PM by dvb projekt

As many of you know, i am using the Texas Components TX2575 Bulk Z-Foil resistor for a long time
in important circuit positions, especially as I/V resistor.

Recently i stumbled over a short recommendation from Thorsten Loesch.

In susequent builds I compared to Rohpoint (which I have used extensively and found no reason to handwind resistors.

In my commercial designs we use a specfic type of SMD resistors after auditioning tons.
Some SMD resistors are really bad, some are so-so and some are most excellent, though no patch for a Rohpoint Squaristor GR102.

Ciao T

Because i know Thorsten as a man who had the perfect sound in mind,
i ordered one pair 30R to try them in my Tube-I-zator.
