I got today my second PP2000. This was the worst sounding unit, the one that I used for over 2 year, was fine then was upgraded to the new version and lost it sound. The first fix of the upgraded unit was not successful but this last one looks like m...

And you are right that it also has a regulator within the power supply. This is stated within the owner's manual but it would not allow me to copy it. They use rather convoluted language. Maybe this is the result of translation?To quote from the r...

then the idea of amp bypassing is relevant to the "clean signal" discussion. But regardless of the measured voltage out vs. driver sensitivity I suspect that there is too little of something in the way of drive and control between a&n...

[quote user="Stringreen"] My opionion is that there is no absolute tone - just as there isn't an absolute sound. [/quote]I disagree. I do not know how about the absolute sound – it would be a difficult subject but “Absolute Tone” is not only ease be ...

Hello Romy,I am no power expert but here are my observations on your situation.Even though a PS Audio and others create a perfect AC sine wave this does not seem to be the answer, even for low draw front end components. It seems that some type of&nbs...

Well, it is a good subject and my reply probably will be lengthy. However, do not expect to read anything worthy in there as I have no answers.

Yes, my friends called me that too, but hey, I can't help it, my curiosity on tube amp get the best part of me, plus I can't build enough power amp to power all my 3 tri-amp system. I collect all kind of transformer, just for the 845, I tried about 6...

Roman,
I can't follow most of your arguments. There are many ways to do things and to lay out the architecture of a system. This line/phono combo was designed to work together and to the given requirements. 75-85 db of gain ? Remember thi...

[quote user="hagtech"] I run the driver tube at 170V @20mA. I don't think you need to run this tube at high current. It is very linear with wide signal swings at this bias. [/quote]
Good operation points for use it as a driver. You might...

[quote user="Markus"]I have recently been thinking about efficiency. Apart from enabling you to use low power amps, is there really any reason why high efficiency is better than low or medium efficiency, all else being equal (and I know perfectly wel...

[quote user="Dresden"]… One very important component I'm leaving out of the cost of the horn is amplification (the horns will be active, using class-D amps). The reason for my choosing class-D amplification is that the modules and various compo...

[quote user="floobydust"] The main component that limits low-frequency response in any SET is the OPT. For these initial designs, I used the smallest Hashimoto SE OPTs... their H-203S for the 2A3 and their H-507S for the 45 which are rated at 7...

All those vintage speakers are not interesting. Among the contemporary loudspeakers, I also to do not know anything that I would consider unarguably worthy.

Interesting, Keith. You got 95db at 23Hz, I thigh the idea of to use tapped horn it to get more sensitivity. Did you intentionally did not target 102-103dB or you went for wider bandwidth instead of gain? You also use 300w SS amps. Did you try to use...

I have the Zu Druid's which Romy has referred to. I purchased the speaker's based on the presumption that their high sensitivity and impedance would be perfect to run SET amps. After having read the great success Arthur Salvatore had running the Fra...

Lx_, it is so and not. I never made a secret that PP has some sensitivity to line before it but for the people who do not use it the degree of the comment would not be possible to understand. Even for PP the relative degree of the comments like my co...

Anybody who ever tried SS amp with compressions drivers or the drivers of high-sensitivity that can be driven by minimum current knows how it works. Nelson Pass created with his First Watt project a lot of publicity to the idea. A few watts, in p...

Wow! I did not realized that almost 4 months have passed since I wrote last.
