I do not see why substitute
between 12.1k and 12.0k would be a problem. This will slightly change the driver
bias and plate voltage as the result but the natural discrepancy of parameters in
the tube is very high and you shall be still within the ...

Many people know that I run a side business doing wedding photography. During the 24 years that I have been doing the wedding gigs, and after over 950 jobs that I went through I kind of have seen all imaginable wedding bands. Certainly the “events mu...

I made experiments running HF filaments from dedicated Hammond 6.3V transformer vs. lifting ground on my 6.3V IDH filaments. I did not listen Sound but rather measure the noise – the result was identical. In the best cases I was able to get 0.63m...

[quote user="drdna"] What was more concerning is today some 60 Hz hum also re-emerged in the system, sounding like a vibrating cell phone going off in the back of the room. It was interesting how it was sort of localizable, but the hum is annoying. A...

This is about the Focal Utopia TN51 tweeter....
It is hard to imagine not much I like this tweeter, in fact there is something insanely beautiful in this tweeter and from a certain perspective (narrow-certain) I like it even more then the HF o...

[quote user="Lx_"] The second sentence is my own conclusion. It was not my intention to imply that it is yours, sorry for the misunderstanding this may have caused. We both agree that PP can be sensitive to incoming AC. The context and circumstan...

Since Sound in new home is mostly set I kind lost interest to do anything “project-wise”. I play my music and I gradually tune ingredients to get the sonic mixture that I accustom to. Last two week I was slowly playing with my analog setup. Since...

It was an interning event last night. The sound turned incredibly bad from electricity perspective. I did not have anything like this for a year or so it was very bad and it was clearly electrical. The PP2000 was working fine and the distortions ...

A visitor of my site, a guy who never ask stupid question about audio, asked me a question how to find a correct size of the back chamber of a straight upper bass horn that he juts built. I wrote a reply but then realized that it would be worth to up...

[quote user="Romy the Cat"] 1) Horn loaded drivers are narrow-bandwidth transducing system. The wider range a horn channel covers the more it conflicts with restrictions of own topology.
