I am having a LOT of microphonic trouble with the 7788s in a high gain stage. I run a 40mV input signal into a 7788 triode at 15mA CCS. Plenty of gain, nicel output. But dang, if I bump the tube or board or chassis, the grids inside...

[quote user="Paul S"]Romy, I am on the verge of an L-pad for my HF ribbons, but in my case I believe it is mostly the MC cartridge response I am wanting to offset, on a case by case basis. [/quote] Hm, this it VERY bad. Fix you cartridge setup, it's ...

Romy,I tried before to cover transformers by foil sheet, it didn't help. Now I try “disconnecting
trick”. The hum was disappeared after phonostage had switched off, while music continued to play.The filament ripple is 32m Volt (5% from DC level). I...

N-Set,When I looked very briefly into the subject, as I was looking for some damping material to use in my tube preamp/phonostage, I contacted Gelmec who were very helpful and professional as a company. They will send you a small selection of sam...

Here is some kind of MM phonostage with around 45dB gain. Two stages direct coupled with input pentode and output capacitor.

So you showed off with your rocket radar something called Omni Gone here:http://www.whatsbestforum.com/showthread.php?6068-Omni-Gon-The-Final-PhonostageWhat caught my attention is the switching of the phono inputs (since there are multi SUT'son board...

Thanks, Paul.
I never saw this company. I did call today to the guy who run it and had longer conversation with him then I intended. Size and shape wise it was exactly what I was looking for. Unfortunately he does not do matching transformer b...

Yes, the fragility of the marking is a very good sign on some German tubes. Still, I do not see why the people who would like to fake them nowadays could not reproduce the washable marking. They have learned how to make the diamonds under the bottom ...

Yes, the dream is that someone will somehow come up with something that works on amplifiers.But right now I'd be happy for something that worked on my phonostage! How hard can that be???Hell, I've gone so far as to take my pre-amp off the grid!...

No, VTA is not in and of itself a characteristic of Sound; but in my own system the stylus' vertical tracking/rake angle is not something that results in the same sound no matter where I put it. In fact, even small chan...

The people who use a single driver speaker believe the while their driver move back and forth for it also radiates a problem-free MF and HF. Near the same people believe that if an amp has capacitors with precious metals foil then it not only do ...

[quote user="Romy the Cat"]So, my question to you guys: what techniques you use to filter out just wana-to-sound-intelligent audio people what you are engage in random let say phone conversation? Did you develop any practice to recognize that the per...

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...

that you specific PP is defective. If it is then all bets are off.

Completely agree. And I will say from the forum members here who have ...

Since the 2007-2008 alchemic music season and consequentially live FM season was over (the event I marked with my “End of the live Phonostage”) I have been spinning a lot of vinyl lately. So, I spent some time with different phono cables with my diff...

[quote user="Paul S"]Romy, doesn't Tim de P also use this cool Miller capacitance idea in his never-mentioned "high end" tubed corrector? Also, do I remember reading that he runs both channels through the two halves of the same twin-triod...

I was reading one commercial audio site where it was said: “….each MAS product is totally assembled and tested by one of our trained technicians who sign his name on the finished product. “ I wonder - why it is not a normal practice in high-end ...

I have been running my nominally 8 Ohm speakers from the ML2s' 4 Ohm taps for quite a while, in order to keep the sound from getting squirrilly and to keep the bass strong enough.Today I used the re-capped/improved K&K phonostage as a source and ...

Hi Romy,Interesting test you have conducted. Were the responses mostly unflat near the frequency extremes or was there variations even in the midrange? The reason I ask is because if you look at most of the published curve responses it is...

I would not say the circuit (per se) was becoming more sensitive to tube choice (and neither would I claim it's not...); I would say that as I have developed the system I have been better and better able to hear what more and more piec...

At the risk of sounding like a yahoo, can i ask you romy if you have used your PC for internet radio playback. , as opposed to cd or other forms of digital playback ? My cd collection played out of iTunes to my DAC sounds lifeless, pointless. Howev...

SOS, DC from PP output would not make PP unit itself made noise but will make some PS of the components connected to PP to have buzz, mostly mechanical. This type of noise would not fluctuate with volume. If you claim that you have buzzing then afte...

After 4 days of suiting in boxes in my listening room today is my day off and I decided to dedicate it to play with the new Pure Power 3000+.
