Interning, I never heard about them. Might I ask you what triodes were used in this thing, how many stages and what “most advanced RIAA available” the unit use? I understand that it is passive EQ but what is so unique about it? Also, if it might act ...

Paul, after a month of vacations I've tried you advice:[quote user="Paul S"]If you can do it, try isolating both cases/chasses from your "ground plane(s)". Use one inclusive "ground plane" for both the PS and the gain/RIAA sections, and ground this "...

It is exactly what the “End of Life” means – you know all necessary answers and have no needs to prove anything to anyone. I heard from you before that you do not like 834PT’s sound, I presume that it was ether bad 834PT, or extraordinary-horrible st...

If you can do it, try isolating both cases/chasses from your "ground plane(s)". Use one inclusive "ground plane" for both the PS and the gain/RIAA sections, and ground this "ground plane" to the house "neutral" wire. Do NOT connect any shielding to t...

Angelo,Although the idea might be looks like an “elegant” at a hi-fi shows but unfortunately it has a lot of pitfalls, the terminal pitfalls for my point of view. This is only my opinion but still:1) LF channel- the bassmaxx. I never had or hear...

Hi,[quote user="Romy the Cat"]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...

Sometimes ago I received an email from a NY guy that I know:
“I borrowed a friend's Sansui TU-X1 and just like I heard them at your place it sounds fantastic! What is it about this tuner? There is such an ease to the presentation and no distra...

Do I remember that a big part of Romy's choice for a pre-amp was based on the specific needs of his DSET Milq, with it's inter-stage X/Os? And do I remember the Placette Active Pre-amp has consistent, fu...

Thinking further about what AMR PH-77 is trying to do some ideas come to me…
At my photography life time when we use to shot on color reversal films we included a gray scale. I personally never was huge fun of this practice as the E6 process ...

Nope, if they said that it has 64dB then it has 64dB and I have no reasons to doubt. In reality the gain stages sum 84dB and 20Db is eaten by RIAA. I do not know how they got from 3 stages of
6SN7
84dB but if they claim that the...

[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 ...

[quote user="Thorsten"]If you do, do seek out old Air dielectric AM tuning Capacitors. You only need 110pF & 330pF, both can be found suitably. Once you tuned the RIAA to perfection simply superglue the shaft in.... I used to use that trick in pr...

Experimenting with Decca carts, I've temporaly disconected the SUT's and decided to check the RIAA calibrationand I think I have some (circuit?) problem.[quote user="Romy the Cat"]
In the end of everything I was able to get very nice response. The...

The TAP TVC does happen support a fully balanced topology, for whatever that's worth. I have not discovered anything difinitive about this for myself, however. I can say that I do not consider the unit's situational neutrality as anything...

[quote user="Romy the Cat"] It is not a the thread about Allnic but LCR RIAA correctors, still there was something expressed in here about the Allnic LCR phonocorrector… and I feel bad about it. It is not that I don’t think that Allnic LCR phono...

Rowuk, we do not disagree about the "battery/dynamics" equation. As you know, the "accepted notion" from the pundits is that "battery phono stages lack dynamics", and the one expensive unit I've heard did seem lethargic, albeit in a "salon". Howeve...

Hi Jack ,Thank you for your very educational info ! It looks like you are right , and your tubes are rebranded SG13P .... Maybe a big stock of those tubes were exported , and you know them better than we do :-)And another question . You wrote :...

Hm, I just paid attention that over 1000 people have reviewed this thread… I’m keep receiving emails form people who feel “insulted” that I did not keep the popular DL103 and DL103R at the level of respect as it treated by those Audiogon intel...

Hi,

An interesting devise, They allow to adjust the midle point of the RIAA curve. I never have seen it and I wonder why would it be necessary or desierable?[/quote]Well, a range of mono EQ curves (and o...

1) Be very careful with use Halco resistors. They were very good 15 years back but they turned south very aggressively. I bought a party of Halco in 2005 and I forced myself to trashed them as they were very noisy. You do not use then in critica...

[quote user="Romy the Cat"]Did you try just for test to increase the caps value that short the plate to ground? Will it amount and the character of the noise change? [/quote]Just like one would expect: 0.1uF shorting cap gives approx 4x more ham than...

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...

Me being exuberant about the new ULF capacity does not necessarily mean that ULF contribution is right and proper, let me to explain. There is a musical event that has it sonic representation. This sonic representation better or worst was captured by...

Perrew,I do not know if you use sarcasm in there but Lamm LP2 is not my bellowed phonostage. In fact I am one of the very few people whop do not like it at all. How much in what I do not like in Lamm LP2’s MM section com...
