Nope, the Russian tubes generally much, in fact much worse than western equivalents. There were however some exceptions. Those options were due to various reasons. The tubes like GM70, YO186, 1P24B, 6E5P, 6N30P, BO188, GM57, UB180, 6C33C, 6N6P, M...

I do not think that 6e5p driver stage withh ss could be useful for proper playback. or would it somehow be melq.
I am familiar with the proven method. in the case of melq it should be followed 100% exactly. I am very greatfull for ...

Here is the general specification for the parts that I used. The selection of the parts implies some liberty of course. It will be your amp after all, not mine - do whatever you wish. In some case when I feel that requirement is critical I will stres...

[quote user="cv"]...yes, I remember. I wonder if it's due to the large (and varying with signal) capacitance of the 6C33 input interacting with the small coupling cap. Hopefully this will be less of an issue with the 6e5p/6p.[/quote]Chris,
It is cer...

I received a comment form people who reportedly well-familiar with using the high-frequency high gain tubes. They suggested me that the resistor between screen and grid (R23) might be eliminated and that would bring some benefits. It very much might ...

[quote user="cv"] Consider a triode connected 13E1. 95W dissipation, will probably work beautifully with the existing OPT if you adjust the gap down and if you can rewire your arrays to present a somewhat higher impedance.Something like 400V-450V / 2...

Hi Romy,So, six channels are now operational in the first DSET. By up I mean the anode voltages on all tubes is about right and the currents are in the ballpark of where they need to be. I am yet to check the DC Offset so hopefully that goes ok.Ini...

I think it should be somewhere posted for my and perhaps for others future references. Here is the setting for testing Melquiades' single-stage tubes on Hickok 580/580A tube testers. To test the tube as a driver for a full Milq (two stages) set ...

This idea keeps to fascinate me.

[quote user="Paul S"] The truth is that if most of the seekers at this site knew what they were really in for by "copying Romy", then they would be wise to give up now.[/quote]

We all know how low-power SETs sound driving low-sensitively ported speakers. The Morons feel that it they have “enough volume” then their SET is good to go. Of course it is not the case and low-power SETs shell not driver dead speakers.
However, I ...

I got a forwarded email today containing the Lamm Industry’s release notes about their new SET amplifiers.

[quote user="be"]Could you tell a bit about how does this:
"I end up with 360V on B+, 15K plate load, grounded cathode, 160V on plate and -3.5V on grid via a series battery."
sound as compared to the normal Milq bias?[/quote]
I did the following. ...

Anthony and Romy, thanks for taking the time to respond to my question. I want to take on this project as a learning experience both in terms of simply building an amplifier from a schematic and for my edification on sound reproduction.
I’m starti...

Well, any tube might be full range, the question about implementation,
power and objectives. I do not know what specifically this fellow does and what
he wants to drive with it. My experiments with single-stage 6e5p were not so
promising. He has d...

The new 6-Channal Milq is up and running, I did manage to calibrate everything in the Macondo’s left channel and was listening it for a while. I might report somehow a controversial result. The MF drive with a single stage is incontestable king – it ...

If one dht is good, two must be better?
I don't know. Some people like combining 6C45 etc with DHT, supposedly mixing the appealing qualities of each. Other people find that using a 6C45 (or other high-gm tube) with a 300B just makes a 300B sound...

As I promised, I am informing about the fate of the Baby Melquiades project. The Baby Melquiades was armed for few days with new 60H transformer. The result was not positive. It sounded OK but it was not even close to the Melquiades sound. I wa...

[quote user="Paul S"] I really would not know where to start with most of the crap out there, since most commercial SS sounds like it makes "music" by inhaling it. But I've heard "acceptable" units from those listed, albeit in some poor environ...

Ok, I have both channels up and running and it looks like it is almost it. It left only re-measure everything , properly calibrate and tune up the port. So, how is it?
The project is success, it sound very pleasant and not anion for non-critical lig...

I have been contemplating for a week if I need to drain the power caps in my new revision of my power amp. The benefits to live the voltage in there is the cap continue formatting what the amp of off and it minimize the need to break-in or to train t...

Well, I spent today a number of hours trying to advance my observations regarding abilities of the one-stage Melquiades. It was quite interesting. Thankfully the electivity today was way better during the second part of day. I loaded the 6E6P heavier...

My project to add 3 one-stages channels to Super Melquiades look like progressing (it means I will have the new 15,5:1output transformers very soon) and in context of upcoming changes and, after long consideration and some tests, I desire...

.. and therefore I do not know how serious to take you.As far as I know as now there are no people who have built Melquiades. I know that up to now about 5 attempts to do it but no one finished it yet up to the point that might report result. Dima is...

[quote user="Romy the Cat"]It is unquestionably an ambiguous project. The topmost question that I would ask myself after this project would be the following: can Milq-biased 6E5P to be as good (sound-wise) DC driver as some vintage direct heated tube...

CV, Good scenario as well but my leading idea is slightly different. I would like to keep any reactance from the path, would it be inductive of capacitive, to assure ultra fast response time. Basically I would like to maintain the MF amp as it used ...

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.
