Alas, not much time to deliver the promised treatise...So, tantalisingly, I will suggest this; for the range 1k up, you would have no problem getting a small mumetal OPT made suitable for the 6C33/S2 combination. Actually, I have something simil...

Chris, may I ask you about this air core transformer for HF? When it decays at the bottom then how sharp is it? Is it usable right up to the roll-of or it should to be "given a space"? Also, did you do any listening evaluations of this air-core ...
|
|
Alas, no time for anything at the moment, the listening valuation must await construction of the amps (and speakers...)Also, it is a very custom application - it is designed to drive an array of ribbon tweeters. Normally these have matching transform...

Hi,[quote user="cv"]Fairly sure it was a typo, but the bigger the airgap, the *lower* the inductance, all else being equal.We need a large airgrap for a 6C33 due to the high current. The advantage is that the airgap linearises the BH characteristic o...

Chris,
Since I got that mind-boggling result with “Melquíades” (will finish the thread about the Melquíades sound) I went for an “ultimate solution” for my installation: a “Super Melquíades” amp. It will be dual chassis (amp+PS) 3-chennal amp to mil...

This thread is a derivation from the thread:
An ultimate transformer within a narrow bandwidth?
Since my Super Milquades is up and running I’m wondering what can I do with the output transformer at HF channel in order to push the envelop of “possi...

I do not think that it needs to be with center-tapped secondary but rather with symmetric secondary. I have good transformer with Faraday Shield that might take 6.3V or 12.6V and give all my DH voltages and with secondary that would be completely...

I got new coils for my MF DH DSET output transformer. To read more about it: http://www.intactaudio.com/forum/viewtopic.php?p=4171#4171...

Hi,From Pieter:"For me it is normal practice to do good specifications.
I go for 10 Hy's at 250mA.
10 Hy's with 512 ohms source impedance will give 8 Hz cut off frequency."BestDominik...

You can gap it for 250mA or for 300mA – you still have some spare inductance. From what I see Pieter gave you a very good price for that chunk of core. If I decide to keep my “experimental” full-range SET amp (Sun Audio) then I will get from him a be...

Not to go overboard after only 2 days of operation, but the Bent TAP (transformer-attenuator [passive] pre-amp) is a pip in my system. It is as "neutral" as anything I am familiar with, compared to by-pass (with CD). I love havi...

Romy,I think I'll try your suggestion. When you say "mappable transformer" do you mean one with multiple primary taps, like 3.5K, 5.5K, 8K?Gera...

Dominik, I think you took it a bit wrong and delivered to Tribute a message with a wrong accent.
As I understated that was the reply from the Tribute guy. No one accuses him in cutting down core size but based upon the available inductance you...

I found an interesting flow in the sound of my current OPTS and while it will be certified I am experimenting with park of amorphous core transformers that left over from my former projects. I am trying to remap my Tribute but it is just 40mA. It...

I know it does not make any sense but it looks like the power line before PP3000 does matter. I took today my large 3kW isolation transformer and place it between my dedicated line and PP3000. I lost my lower bass, simple as that. Yes, the isolation...

It happens that I lately become heavily engaged a project that covered me from music-listening and the Morons-insulting person into a soldering and a constantly questionsasking Moron. Well, it is life.... :-(
I lately have some reasons to think abou...

chaps,I found the design details; it was posted by on the Joenet a few years ago.Basically, it involved making a vertically sectioned bobbin; start with a 70mm diameter cylinder of whatever material (I used white nylon cos it was available and cheap;...

[quote user="hagtech"] For a single driver, looks to me like you need an input signal of at least 3Vrms. A lot of linestages can do that, so a single tube power amp seems both reasonable and interesting. [/quote]
What actually I discovered the...

Hi.
Just remembering I am not technically capable to do any actual statement.
About the GM-100 I guess so. NatAudio has an amplifier using GM100 but with solid state power supply. Magma.

Dear Romy,
I truly am sorry to hear about your loss. You certainly do not deserve this. If it is any consolation you might like to check out
the following website for an insight into the Bent transformers in relation to Expres...

When I said “cable” then I meant whatever cable might mean, the sonic qualities and whatever comes with it. You cartridge with it 2mV drives a cable to a transformer, for instance 1M that has impedance, capacitance and so on. The transformer has 26dB...

Hi Romy and other fellow audiophiles, what is your experience with passive transformer based preamps? Is this the ultimate way to get a perfect variable gain? Or do you prefer to use an active preamp?Chris ...

First of all: I have moved this thread into the Milq Forum…..
[quote user="RonyWeissman"] I'm going to try and build a Melquiades type amplifier (with some help from friends) following the advice given above to make it as simple as possible.&n...

[quote user="Thorsten"]I wonder, which specific line level interstage transformers have you tried, it would have to be ALL of them in order for your statement "there are non" to hold.......But, what specifically do you object to in these transformers...

First of all thanks to all who assist me with this project, including those who did not post here.
Jim, Electraprinted Jack is great guy but he does not believe in exotic cores, very unfortunate because I like to deal with him.
Jessie, you are righ...

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...

Well, the LL1627A is very good universal transformer with phenomenal flexibility (properly done - with section not with tabs) to load the output stage. It might be a good choice for a full-range amp at 200mA, though I would still prefer to have a tra...

Mani, I did find it was strange that you were getting from insulation transformer better result then from PP2000. They are very different devises with very different results. The difference is like to play a CD from an audio output of a consumer $50 ...
