Well, it is not necessary a fully qualified urban legend as the problem does take please with fixed based 6C33C but..... only under certain conditions. I have written about it a lot on my site but will very briefly recall it again.

Hi Romy
I have a mono completed full range Melquiades and another only with the bias circuit hooked-up.
The bias voltage I get on the 6e5p is around minus 4.4v on both the circuits. This is with the inputs shorted. With the inputs connected to adj...

I did not play my playback since Sunday and turned it last night after 4 days not being off. It was very pity sound. Even I felt that it was getting better after 2 hours I shut down the system as I has other things to do. In the past I have mention...

It is completely irrelevant how frequently an amp switched off and on if a soft start is made properly. A few years ago my friend and I, having the 6C33C based Lamms ML2 (where I do not like how the soft was working) , noted that we both change the o...

This weekend I found some transformers in my storage and I put together the Baby Melquiades headphone amplifier. It turns out to be very cure little amp. It is 9'x9' but has all Milq’s incidents including the choke intuit supply for plates and t...

[quote user="skushino"] Rather than an intelligent discussion about the myth of High efficiency and Low power systems, most of your reply focused on the short-comings of my current amp. [/quote]

Alas, no time for anything at the moment, the listening valuation must await construction of the amps (and speakers...)Also, it is a very custom application - it is designed to drive an array of ribbon tweeters. Normally these have matching transform...

Me! Me! Me! Me! Me! Me!
Me and sub-90dB sensitive speakers and not SET amplifiers! I would rather raise money for Bush/Chaney campaign or to merry a Fidelity Investment business annalist.! However, it is what I am currently listening.

[quote user="behhl"]Hi Romy, but I am simply curious that your Designed-&-Made-Yourself have always had the flavour of the names and places from A Hundred Years of Solitude ... Macondo the village, Melquiades the gypsy ... so why the departue now...

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...

[quote user="Paul S"] I wonder how many cities have good FM programming and broadcasting? Los Angeles was great, back when I lived in Venice, with interesting stuff going on around the clock. San Diego is quite limited, and I get Bupkis f...

I was contemplating the 6 Channel Super Melquiades conversion – it will quite a revision – and I am slowly inclining to make it not 6 Channel but 7 channels…Anyhow, the post will not be about the needs of extra 7th channel but rather about one of the...

[quote user="Romy the Cat"] In the 2008 I have a few immediate goals:
1) Finalize the 6-chennals version of Super Melquiades and integrate it with Macondo
2) Finalize the “End of Life" Phonostage:
3) ...

Last night a friend of my visited me and we spend an evening listing Wagner. He played Wagner himself a lot and he begin to make comments about sound of different sections and instilments in my room. I stopped him as Macondo in the new is no wher...

Ah, you use those gorgeous VPI boxes to host transformers. No wonder it does not sound well, what did you see the anything from VPI sound well? Seriously, I do have those VPI boxes, I do not remember where they come from to me but they are too go...

I detected that the Water Drop tweeter has VERY interesting ability to react to the stage of out stage. I am driving the Water Drop with a full range Melquiades SET. As you know the full-rage Milq use a moderate Lindale transformer with a juts 200mA ...

Hm, I do not know men, but it des not work. Over the last few years I have tried the ordinal metal diaphragm 4 or 5 times and not with the Super Melquiades it is the most successful try but I still feel than it is not the sound that I would like to g...

Hi Romy,Many thanks: the answers are...1. The tweeter I thought could go below the MF.2. The room is 5m x 5m x 3.6m.3. Given size of room, corner location would be most practical.4. LF will have to be compact, hence tapped horn appeals.5. S2 diaphrag...

[quote user="Wojtek"]" The only concern being that ML2 is a feedback amp and Mel not. [/quote] And it is exactly why Lamm is able to drive more or less successfully those sub 90dB loads but Melquiades is not. The SETs with no-feedback are VERY sensit...

Bonkers says thanks for the compliments he is always been interested in audio pursuits. Been a while since he's had anything interesting to rub against. I wasnt paying enough attention. The gas tubes never made me feel the same way as Melqui...

Romy, would you explain / help me better understand how you implemented the HP filter in Melquiades?The schematic shows a series cap after the first tube stage (C3 and C4 in the schematic). I think these are the first-order HP filters, correct?Quest...

First of all this is not a post about somebody replicated Macondo. I use the colloquialism: “Building Macondo” as a reference to building any “end of the life” acoustic system. Building the proverbial Macondo, going multi-ampling , arranging powe...

In Macondo/Melquiades thinking, random process means random result - and that is exactly what happened with Dunnoy. A random driver was placed in a random cabinet with a random passive radiator and random cabinet damping. All subsequent attempts to r...

For vibration control coming from multiple powerful indictors I feel there is nothing better then the “wing strategy” that invented for 6-ch Melquiades. Sine I have all transforms and chokes in toroid shape I put them on L-brackets and lifted them up...

Hi Romy,i want to use the 6E6P-DR (triode mode) as driver in my tube 45 amp.I use a D3A (triode mode) with Anode choke at 180V, 12mA. Grid 2 is connected via 50 Ohm resistor to anode. Grid 3 (pin 8) is connected to cathode.The 6E6P-DR (also 6E6P-E) a...

When I think back to some of the products made over the years I realize that neither we nor the manufacturers really know what makes something sound good. Some of the early pieces made by (and I hope Roman forgives me here) Pass, Van den Hul, C...

...but resistor between screen grid and plate, to my hearing, makes sound slightly unnatural, especially in highs.But this may be not true in your case (i didn't try to use this resistor with 6E5P, only with other power tetrodes), so i think i'll sug...
