Greetings …

nosek 2Do you like to listen to good music?  The illusion of “being there”?  That somebody is simply standing in front of you, or behind you … and singing?  Good sounding Hiend-Audio Systems can be either purchased, or built by yourself (DIY = Do-It-Yourself), or … both. Many fans of Hiend Audio rather prefer to modify, upgrade factory devices, so as to achieve a better sound from a properly designed, commercial product, albeit one that suffers from the lack of those few little “magical” touches, tricks and add-ons. Touches, that will turn such a factory grade device into a truly singing masterpiece. They say that you get the “best of both worlds”: the professional “looks, gloss and finishes” of a “marketable” commercial product, but at the same time, with a relatively small additional construction, DIY effort, it is possible to make it SING.

Whichever way you do it, it is the ultimate listening experience that counts. The MUSIC.

These pages are dedicated to all those of you, who love good sound, but also love electronics, the smell of a hot soldering gun, a drill, screwdriver, etc. For those, who love to get their hands “into things”. To get them busy, occupied. Somtimes even dirty. For those, who love both silicon based, as well as vacuum tube technology based solutions. For those, who like to learn about circuits, topologies, issues, problems, challenges, limitations, but what is more important: about the solutions.

You ask:   ” But will I cope?  Am I fit for it ? ”

As for DIY and modifications: The Web is full of valuable DIY projects – both the easy ones, as well as the more advanced ones. Full of “solutions”, of well documented and easy to follow projects, of schematics and designs, of whole devices, methods on how to modify and enhance them, or various parts, modules, sub-assemblies and building blocks that constitute necessary add-ons to your Signal Path – on your pursuit to achieve a better sounding systemPower regulators, Clocks, DAC boards, Amplifiers, Pre-amplifiers, Buffers, be it tubed or in silicon, speakers, even interconnects and speaker cables

The information is OUT THERE. Yours for the picking. Yours to use. It is just a question of finding it, digesting it, understanding it, choosing the optimum solutions, and implementing it.

There is readily available advice from electronics loving audiophiles out there. From those who KNOW.  Those who tried it and who share the results of their experiments. All of this is readily available on the web.

As the Polish saying goes:
One who “wants” seeks for a way.
One who “wants” not – seeks for a reason.
{“Kto chce – szuka sposobu.  Kto NIE chce – szuka powodu”}

**** WARNING *****   Hiend-Audio and hi quality audio music reproduction is a disease.  It is incurable.  And it progresses.  As in:  ” … Yes, the sound IS very satisfying, … but it could always be just a bit …. better  :)   …”.

I hope you enjoy my website. More about me and my disease – on the “About me” page.

By the way, some of my “oldest” blog entries started rolling off the “Recent Posts” tab on the right side of the page, due to limited space.  However, they are still accessible by the “Archives” navigator on the left side of the page. If you dig deep enough, you might even get to the very first one.  It was called: “Hello World!”.  If you got that one, then you got them all.

1, 2, … THREE Component Amplifier

Voila. The SINGLE STAGE tube power amplifier. With only ***THREE*** components in the signal path. A very interesting development indeed. I returned to the concept of the “High Voltage” version of Ultra-Linear, but connected to the Suppressor Grids (S3). The amplification of the single stage tube pair simply skyrocketed. So did the cathode currents. Fortunate …

Shared Cathode Drain Feedback

A “T”-junction of THREE resistors. Two cathode resistors R1, R2, of two triodes, with their respective currents routed to ground, but via a common, shared resistor R3. Boring? DC Conditions? Things get interesting, actually, as there are also AC signals present here. In-phase, or out-of-phase. This is a story of a shared cathode drain feedback …

GU80 Push Pull (updated)

{{ updated 2015-01-21 It turned out that the asymmetry of the setup, that I observed, is a result of a blown silver mica capacitor, which was hidden / integrated with the tube socket.  It was rated for 500V, between S3 and Cathode, which would be a reasonable value if the S3 was reasonably used.  Not …

The End of Thermionic Valves? – Report, Part III

The Future of Thermionic Valves We have observed from previous sections that when first developed, vacuum tubes were used to perform a large variety of roles. However, the rise of more efficient solid–‐state devices subsequently led to their replacement from many of their original applications. More specifically, solid–‐state became and still is, the technology of …
