[quote user="JJ Triode"]Romy,Try running the left and right signals from the stereo arms, one at a time, into the known-good mono phonocorrector. If the problem is not present then you know the stereo corrector is to blame.Are both left and right ch...

"... and I do not know if 3A/167M is better than anything else and I do not see why the metal socket is necessarily better then plastic – the socket is not the part of the tube."As you know, the 437A is like an on-steroids ECC83, ALL glass built, no ...

Got today a shipment from Tokyo with the OS-106 record. It is the same Ormandy’s Bach with Philadelphia but pressed but Japan. It sounds even better. To hear it today is even more fun than ever. We have very windy but very warm day today and the New ...

So, it has been a while. I have DSET/Macondo in stereo now although there is still some work to do to finish it and tune it to the room. As discussed earlier in this thread I need a preamp with gain and the Placette is just not cutting it for me (n...

Thank you for some great ideas! I was actually reluctant to admit that I made several changes at once, with changed-twice arm wire terminations, new IC link, new "dedicated" grounding scheme, and (most embarassing of all) new tubes in the phono...

I have a mystery – my Second stereo arm stopped to sound right. My Second stereo arm is Micro MAX 282. I have been using it for years and I know it very well. It is not the “phenomenal arm”, it loose to my best arm and I know how, but it is an OK arm...

[quote user="N-set"]... I cannot imagine where the fuck I should have a loop??? [/quote] And you are not alone. Any single person who is chasing noise in phonostage ask himself the same question. I assure you that sun of later you will find it and it...

I do like the assembly. I o not fine it messy at all BTW. I would like to have inputs slightly closer to the grid of the first tube. I would also run the heater wire further from the circuit and decent them from higher distance. With all in place you...

[quote user="twogoodears"]Maybe someone read this http://twogoodears.blogspot.com/2009/05/we-437-based-phono-stage-solid-rock-did.html, worth reconsidering its design - also (partially) using WE 437A - after the last posts discussion at Roman's.....

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...

What is the difference in audio? You spend day of you live in your listening rooms trying to make that cable elevator between your phonostage and cartridge to “sound better” and someone after listening your setup inform y...

I think there is a definate trend here regarding distortions that cannot be ignored. Guy, you pointed out some excessive 2nd order harmonics with the Melq bias point. Hey, maybe so. I haven't really looked into this tube - but I jus...

I made today a bunch of experiments with shielding of the MF filtering choke and I have very good progress. I was talking with different people and had a number of good advises (Come one, people the ward “advise” must have a plural form!) The in...

I got home today, power up the payback and played some bootlegs of Australian festivals that Kostas Metaxas sent me another day. I paid attention that the sound was strange it was too hard atop. That was something new. I put in my player the CDs...

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

Well the marketing power can change dirt into gold, we all know that. I have no problems with manufacturers who offer "such" units. We, the customers (especially here in this Forum) are fixed on the quality of sound. Some years ago there was a meetin...

While I have found the Amperex globes act more consistently than the Bugle Boys I wouldn't call the Bugles uniformly bad. I wonder if they just don't match up with current amps as uniformly as the later Globes? I have a stockpile of GE longplates fro...

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...

scooter,
actually this is something what I am planning to do: to have a few selected items that I will moive myself in my car and then let the rest to be move in by movers. The place is not far from Back Bay. It is West Woburn, right equidista...

OK, folks, today I have started slowly to setup the playback itself. I took the small bass speaker I have and moved it around the room. The room surprisingly bassy, that is good. While I was doing it I was installing my TT, set up phonostage... I de...

Using the AD/DA and employing those Dominus cables I could not believe lived without the tape loop. Plugging Pacific into the loop I in fact save one spare cable and got assurance that I would never will move/plug/unplug my AD anymore. I feel like w...

I made today an experiment trying to record LP. I know people backup LP to digital for dozens years and claim good results. I do not back up my best records to digital. I have no need – if I have to play a record then I play record. However, there ar...

[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...

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_01.shtml

[quote user="Romy the Cat"]Yes, you are right, the voltage divider from 6.3V across 47K and 10K resistors shall give not 0.9V but 1.1V. However, the numbers that are in circuit are not something that I saw in my dreams but the actual numbers that I m...

If a car engine does not stat then among zillion reasons why it does not start there are only two main reasons - there is nothing to burn or there is nothing to light up. The very same I think is about my Second Tonearm. Since all cartridges on this ...

Romy,I used second tube grid resistor, 1.8Meg Holco. (I couldn't find 2 Meg chip and good quality resistor: Dell RN60D or Holco or even Caddock MK-132.)But I felt the deep bus was cut. I tried 1.8Meg Holco & Riken 220K in serial. The deep bus inc...

[quote user="Reggie"]Hi, Reggie here.Sorry Rakesh, but I have to say; what a smug tosser's answer. What the heck does God and Starving children have to do with his phonostage? Is he supposed to feel guilty for being upset about it being gone and why ...
