Yes, Thorsten was the man
that made the initial modification in the EAR 834 and I need to note that it
was not redesign of any kind but juts basic modifications and admitting the unnecessary
things. Even though Thorsten is the industry p...

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+.
I desired to use just records and connected all amps, preamps and phonostage to ol...

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...

Does anybody try to change shunt regulators OA2 to 15K Ohm resistor?I heard from number of people that OA2 is too noisy for phonostage.For example, in this article wrote about this http://www.audionote.co.uk/articles/tweak_ai_p2_phono_mod_0...

[quote user="N-set"] Romy would you care to elaborate on that a bit? In particular have you hear amorphous/silver combination?[/quote] Nope I never had it and even f I did it would be difficult to generalize anything. I had only once a fully silver...

Thanks Romy,I particularly appreciate the advice on the Goto issue, although a sojourn in Japan would be delightful too, come to think of it; in my experience there's no better place for culinary and audio tourism combined. "Local" support in the cas...

Rick, sure, working volltage is important. What does your inverter require in the way of current in order to produce it's rated voltage at its rated current? I can remember times when I measured "correct" voltage when the battery was functionally use...

It sounds that in your phonostage has to good (from electrical
perspective between you ground entry from PC to the unit and the main ground terminal
(presumably it would be the ground of your RCA). Some people feel that it
should be 4-6Ga terminal...

***The proper loading value is difficult to say without knowing your system, as it is partly a preamp and ultrasonic RF issue as well as one that involves the cartridge and audible frequencies. Some cartridges have frequency abberations within ...

[quote user="Romy the Cat"] In the 2008 I have a few immediate goals:
1) Finalize the 6-chennals version of Super Melquiades and integrate it with Macondo
2) Finalize the “End of Life" Phonostage:
3) ...

Rony,
Actually I did try to drive Melquiades from different source. My old tube buffer, my phonostage and any other not DC-coupled source were not able to drive it. The 6-ch Melquiades is pain in as to drive. It has around 5K input impedance ...

Hi!
Stefano just made me aware about this forum, so I registered. Interesting thread about LCR RIAAs, one of my favorite topics :-)
About the gain of the WE437 phono: Since Stefano wants to use external MC step ups, I designed the phon...

Nope, it does not miss anything. They offset the 75msec in input using the inductance of cartage’s coil (I quess they do not use MC). Below is the original thread. You need to buy a chocolate cake and to do a foot massage to your Russian mistres...

Romy,I have rebuilt my phonostage (the pictures after update are added to Picasa):1. Fixed filament. Now a ripple about 1mV (unmeasured by my Fluke). The filter is: C-L-C-L-C
30000uf-3mH-30000uf-3mH-30000uf. I put two 3mH chokes & Nichico...

[quote user="Romy the Cat"]From what you describe I can conclude that your DAC is not good. You said you use DIY wireless DAC with tube output. I do not know what wireless mean in this context, but it is not important. I also know do not like any tub...

This year is the first winter that I live with this new listening room. Last winter the playback was up and I still was playing with minor arrangements of my ULF channels, cable and a few other things. For many months I do pretty much nothing with my...

[quote user="guy sergeant"] It's polishing a turd though isn't it? I listened to the 834 quite a bit when it came out and thought it sounded poor, even for the price. imho, The circuit's just bad. If you do all that to it it isn't really an 834 anywa...

Well, maybe a little cussing first to set the tone. The older SPU's are now well sought after, many will end up in collections at now over inflated prices probably in the Far-East where they are worshipped. I've heard a few older SPU's and even those...

[quote user="Thorsten"]I have kept the 600R arrangement, but I cleaned up the circuit a lot. The new stuff was posted over at the AudioAsylum, not a place you are terribly fond of. If you still have the Phonostage you build it might be worth rolling ...

Hi,[quote user="dazzdax"]Thx for this well written and highly educational piece Thorsten! It appears that Romy is not very fond of the Audio Consulting transformers, could you give your opinion regarding those? What is your opinion regarding the use ...

T, thanks for educational reply. I understand what you are saying and where you are coming from but unit I try better transformer, presumably your S&B TX-102 I would not be able to correlate your observations with my, perhaps too semi-prejudicial...

I've run into that yucky place where words get in the way of ideas.The mastership is what i'm after. My problem has always been the electronic side of it. I bet i could design a driver that would get me as far as a driver could, but i'm always swimmi...

Since the “Hunan Style” phonostage-chasses is coming to me and will host my 7788-7721 (64dB) corrector (that I love) I was wondering where I can get an extra 10-20dB to run .2mV cartridges. You mentioned the Lundahl “amorphous core” transformers...

[quote user="Paul S"]Today I used the re-capped/improved K&K phonostage as a source and I drove the speakers first from 8 Ohm and then from 16 Ohm taps, and I got a very pleasant surprize...... .It certainly gave a clue as to why Romy would opt a...

Jim,
I do not know if you still fighting with 7788 noise but let me tell you something: those Allnic shock-absorbing tube socket adapters are insultingly affective. I act lay made some measurements and I was VERY surprised how much the Absorb-GEL ea...

Lucian,
here is where the beauty of 7788 comes - max Gm with absolutely lowest noise ( the area where Russian tubes reportedly can hardly compete). What is particularly cool about 7788 that that are dead quiet one after another. I have near ten dif...
