[quote user="Paul Costa"]Thanks for your reply.I am in the market for either a new pre-amp or phono and line stage.I know they need around 47k for optimal loading, but what else might I be concerned with.Did you have a look on Agon at the two there.&...

The people who suffer from the vintagtism in audio are special breed of Audio Morons™. Those people discovered a single focus of interests in some kind of vintage item and this focus became a point an unconditional dedication and fanatical devotion. ...

[quote user="Brian Clark"]Per Winfeld confirmed to me that the coil former assembly is rotated 45% compared to the regular SPU such that only lateral motion is sensed. Unfortunately I did not think to ask him how the coil/coils was/were wound. Since ...

The new sites announce that Parasound introduced John Curl designed Halo JC 3 Phono Preamplifier. It is passive EQ, three-position input impedance switch, DC coupled amp stages with FET followers. It reportedly has average noise ratio and unknown gai...

I guess Thorsten is laughing since he should be the main receiver of TdP email. Popularity of a product is a double bladed sword. I do hope that sales of EAR 834 phono stage increased notably after Romy decided to make that circuit into his "end of ...

Hello Romy
This is my first post. Did you take courses in electronics and mechanical engineering or have you learned yourself outside of a structured environment? I am very interested to become proficient in working on/modifying my own electronics. ...

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...

The two stages 7788-7721 phonostge can go at near 70dB and it were what I was intended to put in that Chinese chassis. I would like 6-10db more. A transformer? A semiconductor gain stage? A third tube stage? I do not know…
Actually reticently, two s...

T, ‘m glad to see you around. Your position is quite educational although not an unproblematic. I do not agree with some of the points you brought up (I mean that 103-is very low compliance cartridge - 5x10-6 cm/dyne (except D and M), disagree with ...

It might not be necessarily the new wire. With analog there are other billion reasons why it might not sound as it should. Still, I personally can’t stay listening “new” wire with MC cartridges. If you recently futzed with the arm wire then you...

Looking what we do with our players, transports, A/D processors, D/D processors , D/A processors, externals clocks, cables, mass storages I find that it is all so bogus and so irrational. To my surprise I do not see anybody does what I wo...

While Dima and I were thinking how to get out of our 7788-7721 80dB gain, a visitor in reply to my inquiry above about a “second-type” phonostage sent me a link that make me very much queries. He suggested looking at DACT CT-100 phono module. It is r...

Brian , I never tried SSG cap in phonostage . SSG has a good reputation ..... but I'd prefer teflon for coupling . Mica caps , even good ones like SSG , seems too "bright" for me , but teflon sound pretty neutral ....

Ok, I did find the phonostage. It was sitting in one of the drawers. I do see a rational for me to put in there- to make sure that it would not be shacked during remodeling but, kill me, I do not remember I put it in there. Anyhow, it is back and it ...

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 ...

Paul, perhaps I did not understand your posts correctly, but observing your battery obsession throught the time I cannot get one thing: why the freak you are hooked up to the idea of a small, neat battery powered phonostage so much that you start to ...

[quote user="perrew"]Romy,
I might be confused with the passive and active, but from my understanding you prefer your active 834PT to the passive RC network and passive LCR networks. You also prefer the passive LCR to the passive RC. So 834PT&...

Keith,
I do not know why you go crazzy over it. All that is necessary is juts to mention that you are distributing given audio equipment and it would be it….
Anyhow, the Alnick RCL phonostage, the H-1500 II SE one, do you know anything about it? It...

[quote user="hagtech"]First, it seems like the tubes are starved. They are running very low current. The 12AX7 is also at low voltage. I'm guessing they are running at about 0.3mA at 65V plate. This operating point is way down...

Hi,I have the phonostage with the similar schematics that Romy has.The power supply use SiC Schottky diodes in bridge and 15H choke load exactly like on the scheme in this thread.Is it possible to bypass each Schottky diode by 10-100 pF capacitor?Doe...
