[quote user="AlexBerger"]Hello Romy,
What brand of 0A2 do you use in your phonostage?I used RCA, but after 1.5 years of work it began to spark when phonostage is switched on.I tried Siemens, Mazda and now Sylvania 0A2.Siemens has "disco sound"...

- considering another red tip 12AX7 for the output but given the change was not big at the input it's more of an itch...a costly one at $275

I have no idea where this saga with REL leads me. Even though I do have substantial sonic improvement over the original REL version I still do not know if I like this tuner all together. The 50 years all tube tuner with 17 tubes is very freaky thing....

I recently picked up a MAX-282 tone arm and when setting it up with my test record I'm getting buzzing in the right channel during the bias test tracks. Changing the anti-skating setting has no audible effect. On other arms I have if I set the VTF to...

It sounds like a lot of the circling has to do with which 2A3 "sounds better", outright. In any case, I'm guessing everyone would agree that it is specious to argue about which 2A3 sounds most like some internally-estab...

While my Obbligato caps are traveling from Asia and instead of finish my MF amplifier and listening it I am blowing up my steam about the amp at my site there is a subject that I would like to share.

I don't mind talking about the "soul" of tubes. In my experience, the Kron 2A3 is vastly better Sovtek, etc., and better than NOS RCA 2A3 in my opinion. It has much more "soul" -- to the extent that listening became rather dull without it. I was shoc...

[quote user="Romy the Cat"]I am not sure if you stress the words “sound” or the word “stereo”. I do not have anything to do with mono but properly implemented stereo is absolutely wonderful and I love Take a little portable mono microphone, attach it...

[quote user="Romy the Cat"]Stonily they are very similar in my view with a very slight advantage of 6E6P in delicacy and softness. I do not know what you mean “respond differently regarding vibration.”[/quote]As I had been looking at all these tubes...

[quote user="drdna"]
Well, I experienced the same exact phenomena with using different 2A3 tubes as you remember, which I do believe has to do with the mechanical harmonics in part.[/quote]
I do not remember that, it you wrote it then I mo...

Thanks for the rejoinder, including the corrections and tips, Romy.I well remember Lamm saying that we should junk our ML2s now because the parts are "worn out". While that does not cause me to think he does not know what he is doing it natural...

My younger boy Charlie has developed a bad habit: he goes to
Milq amps, pule the tubes out and throw them from stairs. Apparently, he enjoys
how the broken glass sound and the mommy, daddy or nanny jump all over after it
happens. I think I need to...

Roman, thank you for your thoughts. However - you decided to use 6E5Pi to drive 6C33C, and the filed of competition in this case might be higher - including those E810F, E180F, EL84.. or even 12AT7, or even (probably) WE 437. ...
|

Hi Romy,Am I misunderstanding something about the 6C33C?I had a look at the operating point you recommend for this valve in your 'full range' Melquiades amplifier. The way you are using it seems to give almost 20% THD.Does this sound good or is it ju...

I was rummaging through a pile of tubes and came across a pair of 8233. Medium size tube, gold pins, PQ. I think it might have been a video output tube for an old Tek scope. So I looked it up on Duncanamps. 10W plate dissipati...

[quote user="Romy the Cat"]Even in stock version (but with OK tubes) I found it demonstrate some interesting qualities.[/quote]
So you do not recommend the stock tubes? Is it a specific change you recommend?

A few years ago somebody, I think it was “drdna” from California, told that he has a habit to listen the mechanical noise of the tube hold the tube at his ear by hitting the balloon of the tube. I did not exactly acknowledge it at that time as it was...

My preamp also uses those 0A2 and I have a bunch of "made in USA" ones that look right the same than those "National", using the same orange color for the brand letters, but they're supposed to be RCA. They all failed in a quite short time in deliver...

Hi Dima,Yep, I really think that I get this one right: I never take the time to do any research about it until your posting came. Luckily, I got the clues in less than 15 minutes. If only other things can be like that...About VR tubes stability, now:...

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...

The value/type of the capacitor after the gas tube hugely affects sound. I made quite a number of experiments in past with those caps and I have no idea why it is so. Well, I hardly understand (and I did not see anyone who does) why the “gassed resis...

Yes, it was kind of interesting. The Tentlabs site does not have anymore those popups (and my machines are environmentally clean). I was so surprised when I sow it that I even went to their web site from my “absolutely clean “server that never ever g...

Nope, I am not a big friend of OTL amps generally… BTW, I have seen (did not heard) one Japanese amp that use 64 x 6C19P tubes. For whatever reasons Russians consider that 6C19P as very good sounding tube - the younger sister of 6C33C. It was not my ...
