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...

[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...

[quote user="floobydust"] Integrating multiple amplifier sections and drivers is always a challenge. Doing it with different topologies and OPTs adds some additional complexity due to the difference in response characteristics. Crossover design...

[quote user="Romy the Cat"]Anthony, I do not know what you new buffer is. A few notes. The difference between sub 10R and 300R of output impedance is significant for the load you have (Milq) between your new buffer and your 10Y preamp. The type of th...

[quote user="Paul S"]Romy, isn't this the first time you have tried the film caps for PS and the "ALL-NEW" "SUPER-SOFT" diode bridge? I would certainly go back to known quantities before I did or un-did anything serious. Not that I always...

In fact am not only planning to try an electrolytic capacitor as the LF Milq’s coupling (if I found one with low linkage capacitance) but I would also planning to try the “my proprietary” cooked capacitors. I have to admit that it sounds very s...

Ok, here is the final frequency response for each Super Milq channel. The souse was Denon CD player that rolls off a little atop. I did not measure the tweeter as I have no tweeters transformer plugged in yet. All secondary in amp are grounded. The m...

Jim, I have sent you the tubes – it might be an interesting journey.
I send you:
1) 6C33C that was working with both cathodes approximately a year. It is not dead year but it is deep into retirement age. Run it at 220V and 200-250mA full-tube,...

I am taking about coupling capacitor between driver tube and the DHT. There are zillion way to do it and no one said that they need to be used. No one proved yet that a very good quality of caps shell be worse than other methods. In my case since the...

[quote user="Romy the Cat"]Last night I was listening Zubin Mehta’s recording of Bruckner’s Symphony No.9. It was his first recoding from 1966 with Vienna. I am not a big fun of this performance all together but it has spectacular first movement...

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 ...

[quote user="ml8"]So sometimes i just wonder why do you need 6C33C at all, with your high-sensitive speakers.[/quote]
This thread is a derivation of the “5 Channel Version of Melquiades” thread:

if I did it again then I would not do it in context of multi-channel amplifier
but rather I would make a maket amplifier able would test my ideas with it. [/quote]While I do like the idea of experimenting with MF...

Well, Jim, it is time to say “Oops!” I told to myself do not make any posts early morning unit I eat a bagel but this mooring I disobeyed the rule. Anyhow, I do not know how I come up with 28.5V RMS. Defiantly it was peak-to-peak on the scope and I r...

I would like to share my observations about public perception of Melquiades - The Realty Reconstructions Amplifier.
Melquiades, or as I affectedly-abridgedly call it “the Melq” was released to pubic exactly a year ago:

After 4 days of suiting in boxes in my listening room today is my day off and I decided to dedicate it to play with the new Pure Power 3000+.
I desired to use just records and connected all amps, preamps and phonostage to ol...

[quote user="Romy the Cat"]I was thinking about this: how come that driving 6C33C (in fact driving anything one can imagine) the 6E5P was very fine but driving 2A3 it was dull like hell. I opened the amp and tested all – everything was perfect but th...

I made today a bunch of experiments with shielding of the MF filtering choke and I have very good progress. I was talking with different people and had a number of good advises (Come one, people the ward “advise” must have a plural form!) The in...

Contemplating now how to organize biasing for 3 singe stages of my 6-chanls amp I was faced the dilemma: do I need to bias my tubes. The 6E5P/6E6P are Russian tubes and it means that are very different right from the boxes. The Milq, driver tubes, be...

Recently Macondo was altered and converted into… nope, not into a Super Macondo :-) but in a “Larger Macondo”. The Super Macondo it will be when I resolved how to implement time delays along with a low pass flirter at midbass horn, that would enable ...

I am looking at my posts at the forum and am trying to
figure out when the 6-ch Milq as made. I think it was during the late 2007 beginning
of 2008. Well, the Super
Melquiades then is 10-year-old then….
One
way or another I got my first screw ...

I would like to overview the content of my thoughts on the subject. I feel that the first phase of my interest in single-stage Milq vs. DHT is over and I can make some observations.
The subject turned out to be more interesting and more changi...

First of all: I have moved this thread into the Milq Forum…..
[quote user="RonyWeissman"] I'm going to try and build a Melquiades type amplifier (with some help from friends) following the advice given above to make it as simple as possible.&n...

[quote user="AnonymousUser"]hi-i have downloaded the circuit diagram for your amp but wondered if you have any photos of the "guts" so i can see how you laid yours out ? [/quote]
I do not have a full rage Milq anymore. I have only the 3-chanals Supe...

[quote user="Romy the Cat"] The idea was very simple: to convert the C filter into RC filter, to employ the Silicon Carbide Schottky rectification diodes that showed themselves so nice in 6-ch Melquiades and to beef up the preamp with large bet...

Iraschwips, I do not think that it has anything
to do with impedance at all. You might have sub 1R impedance of your
loudspeakers and perfectly compensate it by wiring a custom transformer that
will perfectly work against lower impedances. I would...

[quote user="ml8"] If you think gas regulators make sound of 6E5P so nice, didn't you try putting gas regulator tube in the grid of the 6C33C, and why? [/quote]
Sure, I trued. It sounded very bad. I pull out of my butt any imaginable rational with e...

Ok, it is a lot of information on my plate and I am trying to make sense of it. Below I will share my observations about the new Pure Power 3000+.
The first thing first. In the post I made a few days back:
