[quote user="be"]Could you tell a bit about how does this:
"I end up with 360V on B+, 15K plate load, grounded cathode, 160V on plate and -3.5V on grid via a series battery."
sound as compared to the normal Milq bias?[/quote]
I did the following. ...

[quote user="N-set"]Risking that the topic has already been discussed and that I postin a wrong category (Romy feel free to (re)move this post:Is there any sense in trying 6C33 at higher volatges and lower currents?More precisely, I've been wondering...

CV, Good scenario as well but my leading idea is slightly different. I would like to keep any reactance from the path, would it be inductive of capacitive, to assure ultra fast response time. Basically I would like to maintain the MF amp as it used ...
|

Actually I care less about the design philosophy in this case but rather about the result. Obviously the 150W-200W (200W?) of Zarathustra’s pure class A would be completely useless for my horns. I would like to have something to drive with that amp a...

[quote user="RonyWeissman"]Hi romy, thanks for info. I am going to stick with the 2-stage plan then as it will not be DSET but full range and my mid-bass is somewhat barbaric at this point. I have found someone to build for me, though we ha...

Well, it is not necessary a fully qualified urban legend as the problem does take please with fixed based 6C33C but..... only under certain conditions. I have written about it a lot on my site but will very briefly recall it again.
Dima might be cor...

I was thinking about the subject for a long time. People in audio love to make generalization, so do I, but in it is not so simple. People attribute to output tubes some “special” qualities but I more interested not about unnecessary drooling about A...

I do not know why people go into low-sensitive loudspeaker and they go crazy in order push the last drop out of the class A2 operation. From a different perspective the Macondo’s woofer towers with 97.5dB sensitivity are low low-sensitive loudspeaker...

Romy, Some very good points here... if I downloaded the correct schematic from your site for the 6-channel Melq amp (also has the term DSET in the title) then you have created a 6-channel SET amp with built-in crossover points. Your first ...
|
|
Okay... I also downloaded the original Milq SET amplifier PDF and have looked at it in detail as well as the 6-channel adaptation (DSET) and I understand where you're going with it... or so I think. In my particular situation, I've owned two pair of ...

It is it, I eventual got what I was striving for a while and now my MF DHT channel is done and the most important is that it now sounds exactly how I need it to sound. The new 25:1 loading turned out to be the key. It is “fast” enough and I did n...

Anthony, I have an unexpected advice to you. Label all knobs,
testing points, input and outputs. Everything sounds to you very logical and self-explanatory
not but, so it was to me. In 12 years you will be looking at the thing and
wondering where ...

[quote user="Romy the Cat"]Make the full-range and then you will see where you are.
Still, I feel that for MF channels it is beneficial for do with a good DHT output
stage instead of 6C33C and perhaps it is a good idea to use DHT driver as well.

Splitting the Lamm ML3 thread: http://www.goodsoundclub.com/TreeItem.aspx?PostID=3595
There are some people who worship direct-heated tubes and attribute to them some ventures (like absent of higher harmonics and a special micro-fineness). The...

In the thread GM70 vs. 6C33C two year back I have written that the only tube that I would like to trey in Milq besides 6C33C would be YO-186.
I am not sure that it might be a right direction or even interesting direction but I picked yesterday a par...

This post is a derivation from the following post:

What is interesting is that I have a few the same types of shields for small 7 pin gas tubes and I have tried tho...

(Romy feel free to move this post)[quote user="Paul S"]N-set, I understand you do not mean to hijack the thread with the Axiom, so I actually tried to make generic and/or thread-related observations. I don't know the 6E5P, but generic issues with sp...

I have no idea why this guy is and what he says, I even have no idea of what language it is but here it is: the 6E5P-6C33C amp in PP configuration.

I kind if cycle my attention on the notion of compression and it is not accidental. When a few years ago I used the hugely dymick NT51 tweeter in my car I experienced problem to set the right volume and I run the volume control 10 times more fre...

Further looking at where I would like to take the new 6-chennal version of the Super Milq I am contemplating a new revision of my bass channel output transformer. Currently I have Jack Elliano’s made 450mA, large, single section LF transformer that b...

Frankly speaking I kind of thankfully drifting away from observing what is going on in the industry and particularly in amplifiers. Since 1998-99 I was using explicitly Lamm amplifiers that were heads and shoulder more interesting then anything else ...

[quote user="Paul S"] I have been surprised that you have not already pursued the Zarathustra for your multi-driver, sealed LF. From your early descriptions of both, this seemed like a natural pairing and the most likely way to go, to keep the ...

Thanks, Chris.
Dima I discussed today many imaginable scenarios. Initially we thought drive a single 6C19P from MF channel of super Milq. But it has some negative consequences… Eventually we decided (it is not final decision but the final with 90% ...

[quote user="Paul S"]So this amp would not have to deal with a crossover? One R and one L in the signal path, it looks like a headphone amp, maybe a dream circuit for a light piston, HF only, given no cap/coil load at the [ribbon] driver. [/quo...

It is impossible to make two amp with the same quality with such big difference in output tubes , the transformer design are vastly different, a 10Kohm transformer would never have a good bandwidth as a 600ohm transformer. I just have to experime...
|
|
[quote user="KOTriode"]Romy, in the contrary, it is very unfair to compare my 845 amp with the 6C33C. The main reason is the 845 amp used the best output/interstage transformer available, while the 6C33C's output xformer is pretty good but far from b...
