A few weeks back as I got the Schaub & Lorenz I pulled the pubes out and measured them on my tester. The tubes were very week and the output tubes were semi-dead. The Schaub uses a pair of ECL82 tube in output stage. The ECL82 are triode-pentode...

ZZ, I'm thinking, ramp up the properly-sequenced DC first (and perhaps we go on from here to the earlier-discussed matter of heating and shutdown sequences for each tube...). After that, when I send signal, I start low and ease up on the volume until...

You need to know that I consider Paul’s finding absolutely ridicules. The 6C33C are very reliable tubes with surprisingly low for Russian tubes defect rate. You juts was unlucky or most likely the person who sold to you your party of tubes...

Celsius, I do not know what CCS you impended, did you drive 6e5p’s plate with constant current source? I also do not know/like 6e5p with battery bias. The only application that I find 6e5p suitable was the Milq-style bias with two gas tube driving ...

Folks,Before we discuss "high distortion" amplifiers, lets us ask what kind of SPL Romy's system produces.I don't know, so let me make some eduacated, conservative guesses.Let us assume his midrange and treble Systems are both 100db/W/m and he listen...

Hm, this is funny you are ask because I spinning now Toscanini 1953 play in Carnegie Hall with NBC. The “New World”… The “New World” is well celebrated work and everyone played it. Here are a few memorable that came to my mind: (with no order)Stokows...

Yep, that Koussevitsky’s recording was fun, which brings another prospective to the entire Prokofiev's saga. Sixty years ago we had political leaders who has some exposure to the cultural feel of our country. I wonder what cultural/musical heritage t...

What is it, 4 years gone now since I got the ML2s? After all my groaning about tube sockets, cheap caps and Russian tubes, I have to say these amps have gotten downright comfortable! Over time I have even come to take these amps for granted, which ...

“Evgeny Onegin” is kind of idiosyncratically-charismatic Russian opera. As beautiful it is the “Onegin” has no typical thrill that the ordinary opera lovers accustomed to get rush upon. It has nether gipsy colors on the stage, nor masquerade grand da...

[quote user="morricab"] The one thing that the Lamm ML2 does differently than nearly all tube amps is regulation of the output stage. They do this with the 2nd 6C33C that is on the chassis. Even the KR amps don't do this and I think it is...

Ok, I made some further experiments driving this time my S2 driver from Milq DH DSET. The hell of the sensitively - it was too much. So, I went for 4:1 inner-stage ratio. The result was very successful and the amp looks like was able to get more...

If you thoughtfully read my site then here and there (particularly in the articles about Lamm ML2) you read my “absurd” comments that the best performing system is the system that do best Sound while the power amplifiers not even plugged in the p...

I remember when I built Melquiades I detected that quietly of wire that feeds the grid of output stage with bias, quality of soldering or any other minute detail on this wire was very auditable. I also detected that the proximity of this wire t...

I admit that regarding many subjects in audio I love to sound, to act or just to be a compulsive. However, I feel that my compulsiveness does make sense to me and ironically it does make sense, quite frequency, for some others (unless they are Morons...

Hi Romy,Just thinking out loud here, but I have been listening to my mono DSET/Macondo for quite a while now and recently changed back to my old acoustic system so that I could poke around in the DSET innards for a little while. The old system (in s...

[quote user="cat"]Will your tracer be able to pump 250-300mA at 230V? Will it be able to supple up to 100-110V of bias?[/quote]Not quite. I designed it for preamp tubes. But then I realized I could push it to cover a lot of the more popul...

[quote user="morricab"]I have a phono stage from the Korean company Silvaweld that uses the 5651 tube in the power supply as a voltage reference. It also is using a Russian 6C19Pi tube along with EF86 pentode as the high voltage regulator. ...

Lucian,
here is where the beauty of 7788 comes - max Gm with absolutely lowest noise ( the area where Russian tubes reportedly can hardly compete). What is particularly cool about 7788 that that are dead quiet one after another. I have near ten dif...

Jim, returning back to the subject of tube testing….
I do not know if you have seen my most recent obsession; the idea of driving my Macondo with 1.8W of a single 6E5P:

I always was kind of afraid of it. Any single zillion years tube I see is “NOS in box”, “measured as new” or “never work”. So, I wonder where those uses up old tubes are gone? Do people trash them or juts sell them “as new”. As many old tubes I ever ...
