People asked me: Romy why don’t you try to transfer some analog to digital and see what happen. I was queries myself and I decided to try tonight.
Whatever I did was in a way half-ass but I was interested in “as is” result. Although the attem...

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...

I do not remember which one I used. I remember that I was deciding if to mount them on chassis vs. to have a small board with tube sockets under the chassis and bring the tubes through the chassis. The board mounting is better as it decuples the tube...

Chris,
when I got those large 7Hz-1kHz transformers I soldered one of them in my regular Melquiades and listed what it did. Besides all necessary bass benefits I decided to see how plate current would behave if I have no limitations for core satura...

Hi Roman et al!Allow me to introduce myself. I have followed with amusement Romy the Cat for many years. He is ascerbic and ultracritical, but he does know audio. We share many tastes, like the Koetsu Onyx Platinum foir instance, on...

This is the project that I been thinking to undertake for years. I have motioned about in multiple times that Vitavox’s S2 lower region is very lucrative but unfortunately not exactly useable if the driver run all the way up, unless you are wiling to...

[quote user="Wojtek"] Why can't you just stack them inserting new horn in between midbas and midhorn and keeping your original arrangement? Since your midbass sits on the floor, the tweeter still should be on resonable hight.I would transform your fu...

[quote user="Paul S"]and dm did say he's tried (and rejected?) several SETs already, in the context of Klipsch Horns.[/quote]No, I didn't say that at all. I said that the were aspects of the 6C33CB's presentation via the Almarro A318B SET, that ...

[quote user="cv"]Funny, I was just thinking about battery powering of amps... I know you have identified that the problem is more with the sources, but it would be interesting and quite feasible with the Melquiades and other components... wouldn...

Holly cow, who could even expect that it will be so! BSO opened today the summer season with Mahler second. Levine is at his, look to be permanent recovery, and Michael Tilson Thomas stood at the podium. Tanglewood Festival Chorus, soprano Layla Clai...

I was yesterday drawing plans for the Zaratustra II’s chassis and was wondering how I might use it. The Zaratustra II turned out to be a little Monster, efforts-wise and expanses-wise. I hope it will demonstrate some results that will rectify the eff...

[quote user="Romy the Cat"] Make an experiment, and I will simplify the case quite assertively. Take a typical compression driver, cross it at 800Hz, second order and load it into a proper contemporary horn (Tratrix or JMLC) of 300Hz. Listen that hor...

This thread is a derivation from the thread:
An ultimate transformer within a narrow bandwidth?
Since my Super Milquades is up and running I’m wondering what can I do with the output transformer at HF channel in order to push the envelop of “possi...

[quote user="hagtech"]I have not tried this tube yet. It might push the limits of the tester. The 6.3V heater current supply is nominally rated at 5 amps. It might be ok to push it to 6.6 amps. I have to think about this, make...

Wavac Audio Lab announced a new amplifier: MD-805MK-II.
http://www.wavac-audio.jp/md805mk2_e.shtml
The amp uses the same idea that I pitched with my “Stands for Super Melquiades” idea – 2 floors with small footprint. The way how ...

Splitting the Lamm ML3 thread: http://www.goodsoundclub.com/TreeItem.aspx?PostID=3595
There are some people who worship direct-heated tubes and attribute to them some ventures (like absent of higher harmonics and a special micro-fineness). The...

Romy:Again thanks for the response. With regard to the most important question, my choice would be to use the standard AM Amorphous C-Core transformers in the short term but the Direct Tube Drive in the long term. As I mentioned elsewhere, I was in t...

As some of you know I’m playing last couple days with Red 10” Tannoys from 60s. My selection of 10” was not accidental -I would like to get as less as possible of that “Tannoy bass” but I did run very far the “Reds” turned out to have 27Hz open...

[quote user="hagtech"] Iwas going to ask you about that funny looking damping material. Then you explained it at bottom of post. Very clever to use mouse pads! Lately I've been using cork & buna rubber sheets from McMaster-Carr....

Ah, last night, after midnight I picked in McMaster-Carr some elements for my proposed Supper Melq rack. Thy shipped it UPS ground and I had it delivered that same day! How they do it? Anyhow, I connected two shelves with 4 x 12” by 5/8” rods. I tigh...

Last nigh I spend a couple hours to listening this thing. Since the amp is done in design phase and the final parts are still in order I can not finish it and close up – it kind of frustrating… Still, it gives opportunities to listen it knowing that ...

[quote user="drdna"] The altered topology of DSET has the potential to have disadvantages. There is increased overall system complexity and this often seems to be a negative. Beyond this, it is difficult to expound, for me, on the specifi...

The recent events in my playback made me to think about he new prospective duty of tweeters. Since the Super Melquiades was enlisted for duty the Vitavox S2 got it’s own dedicated amplifier channel and stopped to “see” the coil of upper bass driver. ...

I spend quite a few hours playing with the new channel trying to ingrate into Macondo but so far not successful.
Since the new channel and the Macondo upperbass horn have identical sensitively and identical impedance I figured that I would drive it...

I do not know, you have to decide to yourself what kind tubes and the most important HOW you would like to test them. For different tubes, differently used the different things are important. I had a few testers and all of them were OK but all ...

OK, now I recognize my S2 driver, thank God.
I was give to my new PS for MF channel one more change today to show itself off. I relayed the Hartmann ‘s first movement of the Shostakovich First Violin Concerto. As I said above the progress was very n...

I kind of disagree with Adrian. The wire, the coupling caps, the cathode resistors and many other things are superbly important but it is after the strategic topology is settled. In my view caps, resistor, wire and other things are responsible for th...

Playing recently with setting up the new 6-ch Milq I again got an interesting feeling about my Fundamentals Channel. The in Injection Channel partially overrides some benefit of the Fundamentals Channel and I have a partial feeling that it would be p...

MochaMike, yes you are correct it would not be the “softness” but rather”liquidity”. Still what you are taking is applicable for the paper cone 4 to 15" drivers not compression drivers. Who knows how the compression drivers will react.
To the rest ...
