Paul,
The idea of the not threaded forum is good that it is always there is opportunity to go back to all there and update own views, or to extend them. In many moths/years when the ML2 stop be a novelty for you, you might return to this thered and ...

[quote user="Paul S"] I heard back from Lamms about the relay pulses. They suggested I bias the amps again and then Lamms went silent when that didn't work. But the problem disappeared when I got around to replacing the 12AX7s that came w...

Paul,I have an L2 that uses this tube (at an alarming rate!), so I try to keep a stock of them... While sniffing around, I came upon a deal on eBay that may interest you (since you are in the US)... Check out item number: 150077022964 ...

I'm way too lazy to double check the math, but it looks on the face of it like the 6N6P is one answer to the numerical problems you've posed so far.As for sound, I would prefer the best 6SN7s. But who can find them and who can afford them, once they...

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...

[quote user="Paul S"] The 6N6Ps I bought are nothing "special" as far as I know, but they are all tested and to spec, according to the seller, so I will also replace my current 6N6Ps when the new (NOS) batch arrives, and I will note any changes in so...

Actually I was wondering what the hell you were talking about what you were bitching that the ML2 socket can not handle 6N6P first. Ether you changed over 10.000 tubes in there or something else was wrong because the ML2 sockets are fine (except the ...
|
|
Keep the driver stage, the 6N6P, as new as possible. This tube is very critical for the given amp. You might get a tube tester and measure the mutual conductance but with the low price of 6N6P I think it is hardly necessary. I would change it as ofte...

[quote user="el`Ol"]Here is the link:http://www.rank-concept.deI have no experience with the Lamm ML-series, I just listened to an M-series hybrid amp combined with the Watt/Puppy 8. This performance was a single fake (though a pleasant one). I can´t...

Just wanted to report that less-than clean 12AX7 pins can cause a switch-on pulse through the speakers just like bad 12AX7s can do. I think it's been about 18 months since I cleaned these, when I first installed them, and I just was not ready t...

I am serious, Paul. Reading your tail of straggling with ML2’s tubes and tubes’ sockets I suspect that something is very fishy doing on with you. There is absolutely NOTHING might be with ML2 tubes sockets. You reported that the second stage of ML2 h...

if they don't try something first and report back on occasion?I finally ran out of patience and tried the damn automotive dielectric grease myself on the pins of 4 new tubes I just put in the Lamms. I also for the first time and again...

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...

I was pointed out today to 6Moons review of Canadian Tenor amp:

*** I too have thought a while about exactly this... there is something that troubles me deeply though about this approach. I have a theory that too small a cap may not work out as well as one might hope. Now, shall I do a Romy and delay revealing my...
|

Your points about "better" versus "correct" and "tactics" versus "strategy" are well taken. You are pretty good at saying things I have thought about for some time but never articulated, perhaps because there was no one to tell. I ha...

"I would not trust any seller who clamed that they tested them." -- R.B.How annoying that your words were prophetic, Romy. The 6N6P tubes just arrived from St. Petersberg in a plastic mailing bag rather than a box, and one tube...

[quote user="Paul S"] Does anyone know the voltage the big couping caps actually see? Yes, I should measure it, but I would rather avoid the drill of opening the amps, propping them up somehow and measuring if someone already knows the answer. Of co...

Well, as I understand there is no truly GM70 vs. 6C33C context yet (sound in the respectfully equitable load) from you and it will be very interesting to hear from you when you feel that you are ready to say something. As I understand they are the sa...

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...

Well, I finally found and implemented a digital front end that I can live with. I have been so cynical about digital up to now that I have kept and used an old, cheap Sony player (albeit one actually made in Japan...) because up to now it seeme...

I read one more page from the Tenor description, before the author begun to talk about sound. A correction need to be made, from the first pages I understood that the amp use 6N6P driver but on the next pages it was not the case. Perhaps I confused s...

[quote user="Paul S"]You have said that there are no "good" 6N6Ps; but are some physically constructed better than others?[/quote]
Nope it was not what I said. I said the all 6N6P are equal, at least among those that I have seen and there are no rea...

I have had a Placette Active for some 5 years now and it was quite a revelation when I put it in my system. According to Guy Hamel one of its most important features is its powerful op-amp output stage with an output impedance of 10 ohms. Since I hav...

It did not last long….
Just a couple days back I was thinking that I will live with my current lower bass for a while and now I feel that I will not. I do not feel that my current ULF is wrong. In fact I feel that it is truly superb but I wou...

OK, it is another direct-heated amp with Russian GM-100
driven by a pair of 6N6P. There are many GM-100 amps out there and it certainly
a good candidate for high power SET amp.
I never heard of this amp or even never heard about the company, and ...
|
|
I think it is a perfectly legitimate amp. The
claim of bandwidth is obviously a marketing BS. Also, I am a bit skeptical of if
a pair of 6N6P might deliver significant current to drive GM100 in
negative side curve and deal with plate current. They...
