It is sucks to live with Russians Tubes. It is particular sucks to live with 6C33C. They are all deferent when they new, they age very ungracefully and differently.
The life with Super Melquiades, where I use 6x6C33C driving individual channe...

Hello first, as I am new on this site...
I have tried a number of high Gm pentode/triode tubes, including E55L and, of course, 7788. All are very linear when used as triodes, but do not bet on very low noise, if that is what you would be after. Th...

[quote user="twogoodears"] Yes Roman... I feel pretty like I entered a sort of "cul de sac", tube-wise... I contacted, few months ago, Western Electric USA and they told me that, at USD 750 ea. they have "plenty" of N.O.S. WE 437A... I've been ab...

Ok, let dive a little bit further into my examination of the subject of Lamm ML3
What is important is to undusted that my view less targets the Lamm ML3 but rather it targets the ML3 as a representative of entire class of amplifiers. When I to...

There is an instrument-making in St. Petersburg, Russian, it call Kazitsky Manufacturing. Nowadays it is a typical post Soviet facility that has no interest but it has an interning history in context of Milq’s MF channel. The Kazitsky Manufacturi...

Romy,The normal bias for the Golden Grid tube for 200V Plate at 200ma is about 70V-80V for the good tubes, the bad tube read 0ma at this bias, when drop to -30V it start reading some current, but can't get to 150-200ma current for the SE amplifier.Th...

This appears to put the internal values of its gain stages into play, which in turn appears to cut the signal path parts count, all right. Since we are not given the (presumed "dedicated") cartridge H, did anyone run reverse numbers to see if this p...

Yes, the fragility of the marking is a very good sign on some German tubes. Still, I do not see why the people who would like to fake them nowadays could not reproduce the washable marking. They have learned how to make the diamonds under the bottom ...

It is possible to do the job with only two humans, but in this case one of them might to be doing a lot of climbing up and down out of the attic.For the final few inches, you might need to extend the forks of the lift; you can do this by using a pair...

My bad experience was mainly for aesthetic purposes with just a couple of drivers, so clearly misaligned. sorry for repeating the comment.
The biggest tower of bass drivers I have used was 4 tubes, dynamics was good but the difference I found aga...

Recently, I have become aware of a strange phenomenon after lifting the tonearm at the end of the run-out groooves. The record surface noise keeps going when the stylus is no longer in contact with the record. I am using a Garrard 301 with SME 3...

Just tossing in as possibilities the old JAN GE 5751s. I had a pair of these that were very interesting, including excellent, very even sound density and truly great LF. The only tubes in my system now are the old, "New York" 6922s in my phono stage,...

I've found they're slovakian company and regarding the product description, they don't produce the valves, they just make a search and selection of the best current production tubes. So they charge a nice fee for that selection and testing. Not bad.I...

[quote user="Paul S"]Is he saying other (lesser) phono stages are class A/B? Better, perhaps, to claim "all SET gain path"? [/quote] What does it mean? Why any state of a phonstage would ever be entering anything then class A?[quote user="Paul S"]Lam...

Was talking with various audio people about the 6C33C I was amazed that people are so clueless about this tube. The people are so filled with some foolish prejudges and faulty notions about 6C33C that I deseeded to put together a brief “6C33C user ma...

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...

Nice to see the glow tubes. Shunt reg for the driver or something else?What type of rectifier/smoothing do the amps use?...

Thanks for the extensive reply. I wish I knew exactly the use the preamp is doing of them and if they could be safely replaced by those alternatives you mention. I believe they're regulators within the power supply. The problem with them is not burni...

My other love and career has been as a metal sculpture so I like to mix the two. It gives me great pleasure to see cool looking audio while ensuring that it sounds a good as possible to my ear. Using 4 of these tubes in my next build, I would like ...

If you have nothing more than low hiss, as you describe, then you are probably about There. In my experience, at any rate, it's either some hiss or some hum, compared to true silence, like the ML2, etc.Do not give up before you try all parts hard wi...

I do not have any special love with GU-48/833 and I named them only as examples. If somebody do it then I would root for GU-48 instead of 833 as the GU-48 are much cheaper, easy to get and Russian tubes tend to be more bassy then western tubes (and l...

I did find replacement tubes OK (online), just not locally, like I had hoped. I have now recieved, installed and tested all new tubes but the 6N6Ps, which have been delayed in St. Petersberg by Christmas mail jamb-up. ...

I am familiar with the fresh 6C33C behavior, and I do set bias much lower while burning them in. This set of tubes has been installed for about 3 months; the amps are operating about 45 hours a week. Before switching them on the next time, I'll t...

Thanks again, Romy. The bias pots, mechanically, are just as you observe.I supposed that the extra current draw during burn-in was normal for the ML2s but I had not noticed it before, since I typically do not bother to check or t...
