I think the key to understanding this case is that it is beginning to look like the tubes that came with the amp all were over the hill, electrically. Since I have no way to test them other than by ear, that is what I have done. So f...

[quote user="Paul S"]Well, I thought I'd heard some nice hi-fi at times in the past, but this is something else, altogether! As the new 6AK5s burn in the amps have become truly uncanny music makers. The "highs" are now such that it has be...

After swapping all the tubes between the left and right amps, the cycling bias current issue (mentioned here in a previous post) seems to have settled.I now have another question, which I hope other ML2 users might answer; first the context: These am...

The problems I've had with small DHTs have had nothing to do with tone, which has been SOTA in some cases, IMO. The cheap-o Wright's 6SN7/2A3 pairing is excellent with respect to tone and even with respect to "authority", within its limits...

[quote user="Romy the Cat"] If you have a chance to hear Lamm ML2.0 then try them... [/quote]I wanted to do that, but they are so rare and I found nobody to visit. But honestly, I am not so fanatic, I was looking for something which doesn't make me ...

I'm working on a project that may be of interest to others, and thought posting to this old thread was a better way than beginning a new post.I use speaker level passive crossovers, between multi-amps (not DSET) and drivers. My desire is to move the...
|
|
[quote user="HookEm"]OK, would you say the weak link would then be:1) Just the topology of Lamhorn (single driver with back-loaded horn appendix)2) Any single driver back-loaded loudspeaker in general3) Or any single driver loudspeaker in generalOr p...

Thanks for alternate driver idea, Romy. Sounds interesting.I certainly do not need all the gain from the ML2 along with my AI M3A phono/pre-amp, so I will give the 5687 family a try once I figure out a decent, fool proof pin-out adapt...

I like the way Steve Bench writes. His understanding is so clear it almost shines through my ignorance.Obviously I am still a long way from understanding these things in either abstract or amp-specific terms, but one part of the volta...

Greg, do you have any experience with the Eminence drivers?When the Audax PR380M2 I use (8 Ohm) became unavailable, Dick Osher specified the 15" Eminence driver as a drop-in substitute for the BZ series.I happen to use a single 15 " Au...

[quote user="jessie.dazzle"]Romy, you may be right in suggesting that I am "going a little crazy in there" (I consider this a compliment btw)... so for now I decided to try some locally sourced precision metal film resistors (Vishays are not that eas...
|
|
Romy,Thanks for the info on alternative manufacturers.
The resistors I found locally seem to be working super well (precision metal film... didn't ask who made them...they are all black and cost EUR 2.80 each). I may eventually replace these with RN...

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...

Well, David Berning is about as clever as they come, Merlin, that's for sure, and you don't hear David making a lot of claims for his gear. That whole step-up, HF PS/carrier idea is pretty cool, all right; I think Carver did one, too, year...

Romy, my experience with the Lundahl amorphous core transformenrs is limited to my new phono stage, and I have have been dealing other issues enough that I am not ready to write much about it yet.Still, there are qualities worth noting...

Hi Romy,I am very interested in what you have found out about the 6C33C tube lifetime because I am using a pair of Silvaweld OTL tube reference (their name for them not mine) amps that use 4 x 6C33C-b tubes per monoblock (so a total of 8). Thes...
|
|
KOT, as you may know, the ML2 has a BIG transformer to make "36 Watts" at clipping; but even with this and the trick feedback it is not the first choice for large dynamic/OB drivers. Of course I mention this because of your remarks about the 6C33C, ...
|
|
[quote user="Romy the Cat"] Good question, HookEm. I would say my answer would be 2, “Any single driver back-loaded loudspeaker in general”. Do not get me wrong, driving your, or any other single drivers would do fine by ML2.0 and you will be able to...
|
|
[quote user="HookEm"] Actually, I would prefer moving towards a more permanent solution (for practical, and frankly, economic reasons); and if that means moving away from the single driver (yellow cone), so be it... Now if having the subs in place wo...

If Lamm had actually used the larger 950s in my unit I would probably be less curious about it, but for mine he used 10uF 935 couplers with small 950s for bypass (... I assume they are bypass caps...). Hard to imagine 10 uF couplers would not have a ...

[quote user="jessie.dazzle"] Make sure the power switch is off, and connect the power cord.[/quote] Unless you are a republican. If you are then you need to change voltage with power switch on and power cord attached.

Given enough time (and enough distance), most "randomness" adopts (or appears to adopt) some sort of a "pattern" or patterns.This appears at the rote level to be yet another variant of the old "musical versus accurate" conundrum. Yes, the idea ...

Possible, I never was a big fun of 6E5P without Milq type of bias. I remember what when I did the simple fixed bias when a few year back I was trying to make Milq to sound “contestable” with ML2 it was racy and jumpy sound but nothing special. I feel...
|
|
The cool thing is how Lamm figured out how to get one's attention off the window, albeit, apparently, through a fairly didactic program of "organizing", "correcting" and/or "mitigating" certain information he realized contributed to that particular d...

With the electricity being so bad my listening has been limited, and what I've been hearing has shifted my focus somewhat, which is annoying, to be sure, but it is also educational. I have been playing around with plate loading a little and not...

I have seen some people built 834P with alternative input and output tubes but I never heard them. I personally tried all imaginable 12AX7-type tubes (AZ, AT, AU, 6N2P and many others) in 834P. Some other triodes were king of better “here and there” ...

So what are we to make of a product like the ML2 amps (using them here only as an example, not a topic)? I have to say I more or less took a flyer on these, since I never heard them in a system I could stand before I up and bought the...

[quote user="Wojtek"] Roman, could you (or enybody ) elaborate a little bit on JBL L8 and its application ? Not so much sensible info on the net besides that its a fullrange usefull in 40Hz-8kHz. [/quote]I do not know, how can I elaborate if I never ...

Well, most metals in air simply corrode over time; we all know that. And running a little current through it can hasten the process. To pick an extreme example, I lived at the beach for nearly 30 years, and ALL connections were ...
|
|
I wish I had other sources for reference, since it's obvious (even to me) that the amps will only sound as good as what they are fed (and what they feed). I think I still have my old CD player around, somewhere, while I wait for my iD...
