[quote user="Romy the Cat"]There are no good ready to go transformer for 6C33C. Tangos are garbage. The 20 years back Tangos were OK for small tubes but Tango is long gone and whatever crap they label by Tango in fact Chinese transformers agglomerat...

[quote user="serenechaos"] on 3) & 4): Dave Slagle, Intact Audio, knows a LOT more about transformers than I do, and the nickle autoformers I got from him work so well, I totally trust his (and/or Jeffrey Jackson's) judgment to over my "guess...

I don't know the 6336, but EL34 used correctly will sound like its driver tube, not to mention the comparative ease of PP scheming. Sure, you need the voltage; but this to me only underscores the low ESR angle. And who needs an inductor/transformer...

I figured there would be difficulties. Thanks for the link, 117 pages of Russian, wow. Transformers came to mind. i did not know if such transformer could be made. 30:1? with wide bandwith. amorphous? I think i have ribbon mic transfo with ratio l...

[quote user="Romy the Cat"] It is not a the thread about Allnic but LCR RIAA correctors, still there was something expressed in here about the Allnic LCR phonocorrector… and I feel bad about it. It is not that I don’t think that Allnic LCR phono...

NSET, My comment you reference was in response to a post by Romy a month or two ago on this thread. He mentioned that he had put an isolation transformer before and after his PP3000 and had gotten different sonic effects depending on the position. If...

I've tried a couple of transformer-based lights, but they made noise in my system; so I go back to cheap battery-based lamp (flashlight...). Of course, noise probably does not matter for CNC... While I'm dreaming, I'd like a quiet, ignorable plug-i...

I also built one. It does not have enough gain for a low output MC cartridge. You need a step up transformer. I use an Ortofon T30....

Paul,
As far as I know the Expressive Technologies have only tow models: the regular transformers and toroidal transformers. The toroidal version (SU-2) is not available publicly which left that whatever the Expressive magnetic available out there i...

[quote user="guy sergeant"] I don't doubt for a moment that there are plenty of people 'who know' who will wax lyrical about the benefits of open loop eq in feedback circuits. There are people 'who know' who will tell me that valve amplifiers cannot ...

[quote user="cv"] Don't be pissed about me keeping you in the dark regarding the ribbons; your comments elsewhere on the Nolas and ribbons in general had me loathe to make any recommendations. I think we may have very different tastes in terms of tre...

...but it will take me N-years and I'm in EU :)I could make some preliminary steps this Easter, talk to my winders about transformers etc.I'm for sure missing the FW and out put cores (AMCC800A will not support 120H at 300mA, low DCR), but getting ma...

[quote user="Lx_"]As to the DC offset, I find it strange too obviously. However as it quickly disappears I am not too worried about it. Maybe this indicates a problem in the soundcard when starting the recording.[/quote]The capacitors, transformer in...

Nope, I do not have the itch with ULF sound but I do have a mild itch with ULF concept. The itch is not strong enough to make me to do something but I would like another day to push the boundary of reality and to see what in behind the rabbit hole. L...

Alex, a cartridge loading has no “right” absolute value, it has of courses a certain fork of right values but to loading of a cartridge up to one of a few Ohms would be depended from many parameters, in some instanced unexpected. In my hands, used as...

There should be an 111dB tap on the Lazy Ribbon, but perhaps you have tried that already. Other than that, perhaps talk to RAAL to see if they can improve the sensitivity a little more with a transformer change (or something else)...it might be quic...

hi Anthony Im not saying to use ribbons (really not) but why you’re afraid of high capacitance that kind of shortens the resistance in high frequencies while you’re not playing the woofers in those (>10k) ?It’s purely AC issue that only appears wh...

[quote user="RonyWeissman"]What is the problem ? Listening to the, for example, rca victor red-seal recordings of CSO /Reiner I hear midbass weight, presence and realism that I do not have with the shelter. It is not the pushing forward or highl...

Thorsten Loesch who came up with the mods, details what caps and why on the first page of this thread. Lacking interest for multiple years of auditioning caps, I just built it that way (2012 or so) and have had no urge to change anything. Romy has pi...

As you may know the 7788 is a high transconductance pentode which should in theory be able to give higher audio resolution than say 12AX7, 6072 tubes in tube mic pre designs. On search here the 7788 was mentioned as being used as the ...

"So, my position is my feeling that LCR might be adventitious and it is what I “prefer” as better RIAA filter. Still, I use my feedback RC, so what, who said that what I USE must be what I prefer?"Romy that is Very refreshing view!Im not convinced th...

Ah, those figures seem more reasonable - 30pF seemed a bit low. Well, I'm not sure what you should be on the lookout for - as you say, it's a completely different animal to having a 3uF in line with the S2. What I would suggest, and this isn't ...

Interesting results. Funny thing about that sweet spot.One thing you might try is to add the output from a 12.6V secondary to the primary side of the B+ tranny. Out of phase. This can be a resonably small transformer that could fit ...

Hi,
Thanks for the info about transformers. It is as I expected, however, that these passive devices are not passive sonically at all. I agree with you that the higher quality of the transformers should lessen the effects I noted (if not elimi...

[quote user="Merlin"]Secondly could you explain which characteristics of the recording are destroyed, and what mechanism David Berning uses to acheive this? [/quote]
Actually it would be a reversed question to David Berning:
“What kind evaluation ...

Thanks for the tech info, Merlin; it helps a lot, especially combined with the preferred music revelation, up the thread.I agree that the OPT figures in to the sound, all right, for better or for worse, and there is no mistaking the OTL "clarity" by ...

I do not know Paul; I feel that you have a lot strange fantasies about ML2…. BTW, this week, because some odd courses, I will have a pair of ML2 in my room. It would be like a déjà vu feeling. If I found myself in the mood then I might look if ML2 us...

[quote user="Merlin"]No. You are wrong. Harmonically, my SET is quite superb using either 300b or 811 I have unfettered access to the music in it's entirety. Transformer cores just distort the signal. [/quote]
Well, I do not want to argue the ...
