Romy,I would like to know, if you do not mind to explain, since you cannot drive your bass modules using SET, why you use Solid State amplifiers instead Pentode or Push-Pull Triode?Thanks!...

[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...

Romy,do not spit in my eyes as I do have solid state PassLabs 350.5 but even with this 50W Class A amp (push pull) it is exactly the same problem if it is switched off completely even for a short while. I can take ~ 2 - 3 days to be back to norma...

romyi never heard before regarding this technique of push pull, ore isobaric design. i searched the net, and i found it very interesting.That means when one driver cone is moving out of the enclosure, the other is also, but, due to the way they are m...

Thanks Romy. The monopole issues I referred to are in the areas of coloration and presentation throughout the spectrum, that can be solved/masked effectively with dipoles. I am very aware of the dipoles' shortcomings in the bass area but they do not ...

I am beginning a small tube project, and Hammond transformers came to my attention. Are they any good? I am thinking
Hammond 1650W for output, with 6550's in push-pull.Thank you....

I just visited the Highend in Munich and had the chance to listen to two of those monster SETs. Cessaro showed up with monstrous 833 amps and my thought was that there is something wrong with the music. I know it is common in this forum to describe w...

Romy,I am very interested in this thread as I have heard the latest version of the speaker "eufrodite mk IV" . I do not think any of your objections would be changed by the latest version as he is now using push-pull array of beyma 8" drivers up to 2...

Well, this certainly shrinks chassis size, if nothing else. I've never looked at the circuit, but there has to be some sort of transformer function at each end, up and down, and the easiest way to do this would be with transformers ;>). ...

I think low power ss design is the only way we can make ss to sound good. in my idea all high power ss design i heard had no emotion in their sound in comparison by good SET designs like AN UK Ankoru.the first SS design that make me happy in comparis...

well fine, my X350.5 does 50 watt class A, and of course in push-pull. I use it with 120 watt max rated 3 way speakers of about 87 dB efficiency. You can see on the 350.5's centre instrument dial if you go out of class A. If I go out, I usually fear...

Romy Hi, Raplh uses a 300b push pull, but the power supplies are massive, parts alone 15K Euros, each channel has a separate supply, the pre-amp again two massive power supplies , he prefers to use eight of the horn loaded bass bins, although I...

I have heard vintage tannoy red (driven by 30w push pull EAR 861) and vintage tannoy gold (driven by 20w set ongaku japan). I think for 92db the 20w is not good idea.http://www.goodsoundclub.com/Forums/ShowPost.aspx?PageIndex=1&postID=3746#3746T...

Wow, I never thought of that before. But you could be right. Perhaps the only section of belt contact that matters is that last inch or two before it leaves platter. Clearly the belt does not push, it can only pull. And if bel...

[quote user="Romy the Cat"]The point is that the people who do “get” what it is all about do not need to witness chewing details and they do not need any explanations – they have own mind and own ability to discover (reinvent) the thing on their own....

[quote user="Paul S"]Thanks, Scott L. I get the math, and no doubt hearing is believing. Still, I do know for certain that "a driver" can be influenced by a defined amount of trapped air in an enclosure, at least as far as the sound that comes from ...

The “Enjoy His Music” published the old celebrated by many DIYers Herb Reichert’s article about his 300B amp ideas.

[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...

Is there a pill for that too? Seriously, it would be very interesting to hear what solution you come up with because I have converted from listening music solo to a small number of audience (friends). So much that I listen by myself much less oft...

Paul,Rather than go SS, perhaps you should consider push-pull tube amps for each of your five 92-93 dB-efficient channels (I assume "channels" means frequency bands, not HT5.1 or similar.) Along with that, consider using a modest amount of global ne...

Hi,[quote user="Romy the Cat"]T, thanks for educational reply. I understand what you are saying and where you are coming from but unit I try better transformer, presumably your S&B TX-102 I would not be able to correlate your observations with my...

I don't know this Steve Klein. I don't know what bullshit he uses to sell Audio Note's products in the US. If that is what you are attempting to satirise then fine.I am quite familiar with Audio Note Japan's (Kondo) products. I don't use any at the m...

[quote user="hagtech"] I run the driver tube at 170V @20mA. I don't think you need to run this tube at high current. It is very linear with wide signal swings at this bias. [/quote]
Good operation points for use it as a driver. You might...

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...
