Hi Romy and all,
first of all, my name is Henry, with a "Y". due to an Irish grand-grand-grand father called "O'Henry". the O' was deleted when my grand-grand father was born, due to a silly servant of registry office. :-) all my horns uses the calc...

Perrew,
LCR is not active at all; it is the very same passive EQ as your RC? I think you a bit confused with terminology. The main logical explanation (there are many of them) is that capacitive filtration is very bad one and need to be minimi...

Yes, and because of this it would be accurate to say that my system is music-...

It is difficult to generalize but I will. As much as ribbons with each hertz down sound more and more unpleasant the low power SET amps with each hertz down in bass region more and more and more loosing ground. Ok, I am not taking about the real bass...

Somebody at AA asked about the difference between electromagnets and perm magnet. Thankfully the AA idiots who pick the pieces of brain at my site and already learned that the idiotic blabbering about “the electromagnets have more flux” is comple...

I admit that regarding many subjects in audio I love to sound, to act or just to be a compulsive. However, I feel that my compulsiveness does make sense to me and ironically it does make sense, quite frequency, for some others (unless they are Morons...

[quote user="Romy the Cat"] Well, I have to admit that I did not listen the whole sound of AC vs. DC filaments yet. I will bring home today my DC lab supply that I use for my electromagnet coil and will give the try. I still at this point am not...

I have to tell you something: I do not believe to audio people. Whatever they say has some freakish twist of desire to present the sings in a certain way instead of witnessing and experiencing the thighs as they are. This is one of the reasons why I ...

Ok, I made some further experiments driving this time my S2 driver from Milq DH DSET. The hell of the sensitively - it was too much. So, I went for 4:1 inner-stage ratio. The result was very successful and the amp looks like was able to get more...

Like cv, I've not directly compared mumetal
to amorphous in an OPT position. However, my hunch is that the sonic
attributes are the same as those found at line level (I've tried
various Xformers as the IV/output stage in my Rakk Dac).
I now ru...

Devo, the GM-100 for sure is a good triode to get 160 watts
output power in A1. Still, it would be a good chose, from my point of view,
ONLY from a prospect of embracing as good DIY audio project. There is nothing wrong
then to do the good DIY aud...

[quote user="nl"] Gordon Rankin of Wavelength Audio did a series of one-stage DHTs with a step-up transformer input about ten years ago. I think they were called the Mercury series. By all accounts, they sounded good, but of course had limited gain, ...

The “Enjoy His Music” published the old celebrated by many DIYers Herb Reichert’s article about his 300B amp ideas.

Joe, I think I would battle it.
I would not be so certain. Mostly the SUV sized bass horns are notoriously bad sounding despite of the assurances of the system owners overwhelmed with so common in audio endowment effect. Not to mention that the Stag...
