If to look at the Melquiades schematic in the channel “A” you will see 78H first order low pass filter.

The low-pass filter in Milq and the low-pass filters generally is great...

[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...

Hi,[quote user="morricab"]the unit I tried (the Sonic Euphoria passive) did not live up to my hopes.[/quote]
Given my somewhat loose but existing ties with S&B and with Music First Audio I need to be careful what I am saying. But let me suggest...

Actually I care less about the design philosophy in this case but rather about the result. Obviously the 150W-200W (200W?) of Zarathustra’s pure class A would be completely useless for my horns. I would like to have something to drive with that amp a...

R,
I note you calimed a fondness for certain softdomes; looks like there are some newer scanspeaks that may have the tonal qualities of your favoured types but with higher sensitivity, which will match the Focal well.
Eg: D2904 types at

Scooter, I was thinking myself if it was a pirated CD and I very carefully inspected it, I did not found any signs of not authenticity but I am not expect in it. To me it looks like a legitimate DG album. Though I admit that with contemporary mea...

I truly enjoy reading the different internet audio idiots expressing their “wisdom” about what I do. There is a site out there filed with typical audio white trash and they suddenly developed a desire to criticize my admiration of FM based upon ...

First, you miss a reference to the phase “I am a very intelligent person”. It was the Melvin Udall’s quote from “As good as it gets”, not that I do not have meaning behind it but the meaning is bit more elusive then it is on surface.

[quote user="haralanov"] So the tweeter is always needed. The bad thing is it deforms (in 99,9999999999999999999% of the cases) the perfectly round audio window, formed by the midrange channel and "pull" some notes sometimes at its axis. These are of...

Collin,I am pleased that you found my suggestions worthwhile.

This week I will be trying to address why the Milq midbass is clipping. This is very interesting one. Currently the Melquiades LF channel uses an output transformer 700R to 5R or 11.83 to 1. I thought before that I have much lower ratio, like 5:1 bu...

Romy, I do agree with all your comments. It is true that the magnitude of the rubber taste very much depends on the crossover frequency. I used them below 64Hz, but with first order filter, implemented before the amp that drives them. With that kind ...

I keep thinking about the strangeness of my phase inversion.
I still do not think that it should be this way. My leading explanation is because
I did not implement the crossover precise. If the crossover called for let way

I was wondering what the noise of stereo signal come into FM and are any ways to reduce it? Naturally we get out stations in mono mode with practically no noise at all. The best tuners more then 85dB signals to noise ratio – that are very high number...
