My favorite performance is in Tele's "Das Alte Werk" series, Nicholas Harnoncourt and Concentus Musikus Wien, on period instruments. Again though, not a live recording (you can even hear the "mix" shifting between some movements) but still very enjo...

Brain, C’mon, I was kidding about the “Electron Intensification Interface”! There is nothing in this phonocorrector then a correct selection of tubes, thier proper (well almost proper) use and selection of the specific topological decisions that sold...

[quote user="AlexBerger"]I think I should to give some break-in time to Sylvania 0a2.50 hours is enough? Previously I used in my EAR the next set of tubes ECC83: 1-Amperex (red print), 2-Amperex (red print), 3-Sylvania 7025 (yellow print).When I ...

I liked your previous post . A week ago I repaired old Telefunken tube radio (Single EL84 with array of alnico speakers ) with FM band and I'm listening to classical public radio for whole week. Not even once I had desire to turn on "big" system I'm ...

Sorry for reviving this thread without a good reason, but there is something I wanted to add to my comments about amplification. Recently I heard this system http://www.hornfabrik-eder.de/ which was driven by an old Telefunken studio amp. O...

[quote user="AlexBerger"]Hello Romy,
What brand of 0A2 do you use in your phonostage?I used RCA, but after 1.5 years of work it began to spark when phonostage is switched on.I tried Siemens, Mazda and now Sylvania 0A2.Siemens has "disco sound"...

Yep, you re right, the Yamamoto A-06S is SET, I did not read it carefully and I was under presumption that A-06S is PP monoblock. Good for Yamamoto! The only amps I heard with AD1 were PP. Somewhere in the very end 90s I shortly was exposed to i...

[quote user="miab"]I'm about to place an order for some 12AX7 tubes. The GA 12ax7 tube you mention doesn't seem to come up in my search. Is there other info regarding this tube?[/quote]I am not sure but it is possible that General Electric never ...

I never had a lot of trouble with high transconductance tubes. I use the EC8020 a lot. Stefano, you might look into this EC8020. I never seen it but just looked into the datasheet and it looks very interesting tube and i...

I closed up the amps and moved it to the default operation position, right along with it all Dominus cables and so on. I played just mono music and was very interesting where I will find myself with this amp Sound. The right channel still was s...

[quote user="Doug Eisemann"] I have stopped by your site from time to time over the last year to see what interesting things have been going on. I generally do not say much, however I finally decided it was time to register and add a few commen...

Each new idea is an opportunity or a pain to be involved into a new round of custom work. With all my considerations regarding engaging the DHT I more and more biased to have YO186 as the leading candidate, in fact I almost decided to do it. Fr...

I'm pathetically slow with my 834 clone, but that's what I am....Sorry for boring you but I treat this threat a bit like a blog on my "progress".I've tried to fight more with PS induced ham and interferenceby putting the PS transformers and HV rectif...

I actually woke up today at 6AM, check all settings on my arms (after a few month of not working), demagnetized the needles and was spinning records all mooring. One of the benefits that I got with new phonostage is that the grounding patters for all...

[quote user="Romy the Cat"] After a few month of living with YO186 I think I know everything about this tube. I do not use the YO186 all time and I think the explanation why I do not use it all time would well describe what YO186 is and how I use...

I don´t know whether the audio industry`s products are so sophisticatet that they need mathematical steam hammers to improve them. In a German forum there is a discussion about a diploma work from the TU Berlin where the student found out in psychoac...

The Adrian’s quote about being stunned and disappointed can’t better express my view on the subject. I admit that I am driven by disappointed and in a way anger for the horrendous sound I got from my Koetsu Onyx Platinum. However, it was not a an...

To me the big green drivers in the midbass horn look like old Siemens Klangfilm or Telefunken (or other German manufacturer) 10 inch units. Maybe 12 inch... I had a pair of 8 inch Klangfilm once and they do have interesting tone across a couple of oc...

I suppose I have "learned a lot about drivers" and speakers over the years, but age has overtaken my production capabilities, and I am selling my stash of drivers. Included for sale is the Holy Grail of lower mid-range drivers, a particular variant o...

[quote user="DHT4ME"] This is true. It comes down to thermal cycling. I love the #26 tube but it is real hard to get quiet. It has a 1.5v 1a filiament. The heavy draw causes thermal cycling which is very hard to null out. There is also more rati...

I've found they're slovakian company and regarding the product description, they don't produce the valves, they just make a search and selection of the best current production tubes. So they charge a nice fee for that selection and testing. Not bad.I...

I have been fighting the electricity and getting off-track enough to find it wearying, not to mention the silliness with the tubes. The other day I happened to drop a double album and it hit dead flat on the carpeted floor. The mute was of...

Ah i just read your article, and its funny that i share the same believ. While you were experimenting with the telefunken field coils did you also notice that the amount of current running tru the field coil also has a great of impact on sound and re...

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...

One of the wonderful things about Bruckner that Morons do not buy Bruckner records. Last night I attended the “Hydra” concert and stop by in city record shop. http://classical-scene.com/2011/11/11/sound-in-space-festival/comment-page-1Here it was the...
