[quote user="Antonio J."]I knew that my asking about the cart used would make you to write the kind of comment you've done. What I've enjoyed most and exclusively of the disc has been the music, all are terrific pieces and some, like the Ko...

I think that picking a DAC is like picking speakers - regardless of the price, we don't know what we have until we get there. I do not think that it is possible to compare digital and analog playback forms. With a turntable we have as many choices (g...

[quote user="Paul Costa"]I have a PDF file of the manual if it interests you to read it, I can email it to you. The unit weighs 80lbs, uses 6 6sn7's. What I found a little odd was the spec for the phono is it says : MM Phono Stage Gain: 64 dB at 1 kH...

[quote user="Bud"]I am about 3 weeks away from supplying 3 Kz ohm to 4,8 & 16 ohm SE outputs for 300b or 2A3 tubes to George Wright, of Wright Sound, and Gary Pimm of Pimm CCS fame (constant current controls to buffer stages from each other ...

[quote user="hagtech"]My Stu never got a reply by the asylum inmates. Maybe nobody there ever heard of a 7788. No help.[/quote]7788, gain/noise/bias vise, as a penthod, is pretty much idle first stage for not-extra-stages low input preamp...

I do not know here to start. I absolutely assertively insist that under normal circumstances it is absolutely imposable to buy matched pairs of NOS tubes, particularly the high Mu tubes. When sellers advertised the “matched pairs” I just discard the ...

[quote user="anthony"]My interest is
mainly in the 10Y/801A/VT25 tubes on one hand and the 45 on the other hand.
The YO186 also interests me a lot especially after reading your
impressions of it in your circuit and system, but it is a very diffic...

Alex,
I cannot answer your questions objectively. It was over 15
years ago when I was working with this phonostage and since I built the last
version, I did not make any experiments with it. I do feel the design is
spectacular, and I am lu...

I decided to make this post in this thread (you are at a second page of the thread) about the “second-type” phonostage. My needs for a Santa’s bring me a nice “second-type” phonostage really got stronger. If you remember my 7788-7721 tow stages,...

Today I was reading Jim Hagerman's interview about his Trumpet phonostage and learn that he uses LCLCRCRC filters for B+ in his design. I certainly do not question Jim’s decision; in fact I never heard this phonostage, but I would like to comment, co...

Hi Romy,
I did the review on the AcousticPlan amp, called the "Santor". It is indeed a two-stage amp using 4 6922 tubes in parallel to drive a high Bias Mosfet output stage (it is class A to approximately 15 watts and runs very hot). It ...

[quote user="KOTriode"]It's 60Hz hum, caused by both mechanical and magnetic field coupling to the output transformer. I used a toroidal transformer and thought it would not caused this problem but it did. When using an external power supply for ...

The top 3 are to scale model of the throat, mouth and length you posted above without the horn profile.the bottom image is the equivalent flat pattern.If you were to cut the pattern out of material and sow the sides together, add a ci...

Well, I kind of understand that my objectives for my “perfect” MF channel I have some irreconcilable differences. Let see:
1) No capacitors in signal path
2) Bandwidth restriction, allowing employ DSET type output transformer wit...

I do some very interesting experiments with Rohde & Schwarz tuner. Dima and I have discovered a way to use the Schwarz without the wide bandwidth amplifier, driving the Multiplex Decoder from the Schwarz’s preamps. Basically we put two stages wit...

Hi,[quote user="Romy the Cat"] After some experiments and still being dissatisfied with the HF I ended up consulting with Dima. He spread me a theory according to which the HF was killed by my coupling Silver Mica cap. All my arguments that sil...

Hm, since I made my last post I was walking around my room, listing music and a feeling that something was very still wrong did not live me. It always there was some sense of presence of HF in sound. It was not my typical full-Sound where it is...

[quote user="decoud"]Yes, but is not the real question *how* different from the Taiwanese company's standard double conversion UPS the purepower units really are. If they are effectively the same topology and components (http://www.winstream.com.tw/p...

I am bit confused with that new report. Under no circumstance I would defense Pure Power, nor anybody want my defense, but the reports I hear juts do not makes sense. If look like Pure Power grade for extra 30% or 50% power with new units, I do not r...

Yes, Jim, you put it very well. Still in case of the 6C33C it only possible to cool the glass and I made experiments blowing a strong flow to the glass and it did cool down the plates. The problem is that it is not a good idea to apply a strong flow ...

Paul-Again the disclaimer - I don't have a schematic nor is the circuit board fully visible, so these are solely my speculations and I could be wrong. 'What is the
MKP's value, and why do you think it's "the" coupler, while the 'Cubes
are else?'I...

[quote user="cv"]I wonder if it is the reactive components (blocking caps etc) that are to blame here, seeing as much of the problem is in the lower bass.[/quote]Chris, what you said made me to think.
Look, the output of Bidat and a SS buffer that b...

I just completed (DIY!) several "factory" "upgrades" to my SE phono stage. While I had no frustrations with the unit, I have been reading designer Kevin Carter's careful explanations of the changes he has worked out over the past few years. These mo...

[quote user="anthony"]I plan to
