[quote user="hagtech"] After many years, Romy has come to enjoy this style of amplification. If I read his words correctly, the sound of these machines brings him more emotion and connection with the music and musicians. An admiral goal.&...

Neat deflect Romy ;)
I see I should try some 7025s.

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 anyway. I used to work for a valv...

Paul, thanks again for a nice input--sounds for me indeed seductive (well, I'm anyway +/- "self-convinced" to give a silver/amo a try).Do you use silver wire also in the tonearm? What I have in mind is a 2nd, all silver path for the 834, which would ...

Hi all,I'm slowly progressing with my assault on the pussyfied 834.I'm looking around for an interesting step up.I've happily eliminated SU-1 (I'd rather daydream about a night withMonica Belluci instead of those ugly steel boxes), said fuck off to S...

I'm pathetically slow with my 834 clone, but that's what I am....Sorry for boring you but I treat this threat a bit like a blog on my "progress".I've tried to fight more with PS induced ham and interferenceby putting the PS transformers and HV rectif...

Hi All, 103 or 103R + mass loaded SME headshell + 3012 or a 3009 + Seiki 1500 + hagerman opamp phono stage (good only with select parts and battery power) or an EAR 834 (with some mods) and some old Altec mic t...

Hello to everyone, am new to the sight. Been reading for a while and decided to mod my 834. I've had the unit since '96, purchased new from the local dealer. I have noticed a few differences from the schematic, the 220K load resistors R10 and R110...

Sorry, Adrian, I did not hear either phono stage in my present system, nor did I A/B them, but I "compared" them in my "aural memory", with the actual listening sessions spaced several years apart. Back around the time of the FET 10, maybe a li...

Romy (and the followers) how do you change loads when using 834 with different carts?I was thinking of low thermal EMF Hg reed relays (the idea I've copied from Romy)A sample part is e.g. Coto 3520-12-911 .If they prove ok, a volume control switch ba...

[quote user="Romy the Cat"]Yes, this is what I expected. That slightly fatty lower range is what I have and I do tend to like this type of response.[/quote]Thanks Romy.Yes, it seems intrinsic in the design. The above curve is simulation, but I get i...

Hi Jim,Your comments about the operating point of the input stage and the resulting even order distortions may help explain why, whenever I have listened to the 834, it has sounded like a syrupy euphonic mess. I can get the same effect by singin...
|
|
Thanks Romy. Given the power of 801A preamp, this correction is not necessary. I simply increase the volume compared to my clone of 834 RIAA or other sources and the autoformer at the output is still in the attenuation mode, providing increased outpu...

Hello Romy A sleepless night had my all-but-derelict brain going round and around the phono stage and, of course, more questions than answers were thrown up. Did you and your designer friend first try an intermediate version of the 834 circuit which ...

Hi Romy,I am currently in the process of rebuilding my 834 PT. I see you don't use the capacitor bypass on V2, does this have any effect on overall gain of the corrector? I've recently acquired audio Technica ART7 cartridge which is low (0.12 mv) out...

Scooter, thank you for the warnings. I already own O2 MkI for +/-2 yrs and got to know them a bit. As I said I do not like headphones in generalbut I have no other choice. I own 2 more staxes: Sigma and Lambda Pro and Omega can do things others canno...

Scooter, if you happen to be in my part of the world, I invite you to stop by my place (I provide accomodation right in the city center) and listen to my EMT with O2.My Staxquiades won't be ready soon for sure, but my source is well operational(refur...

Wow, how much better would the audio magazines be if we didn't have to tolerate the cliched and ill informed appraisals we are normally subjected to?! I completely understand how you perceived the sound of your Lamm experience from this image. I'd ge...

Fucking soundcard...I knew I should rather buy myself a good bottle of wine if I cannot afford a real equipment, but I got seduced by the "simplicity" of mesurements and price...well, I got what I paid for: ~16k input impedance of my Fuck-blaster X-f...

I wonder if you're doing your listening with the Bidat using its volume pot or you're using only vinyl with your phono correctors or maybe the ET-T-834 EAR using its volume pot. Maybe the Melquiades has its own attenuators. I'll be glad to know how y...

Hi Rowuk,Thanks for reply, I use step up transformers, old Partridge 1:12 I think they are model 973B if memory serves me correctly. I haven't installed the ART7 yet. I currently use another AT cartridge - 33ptg ii which is a more "normal" output of ...

Thanks for the reply. My 834 came from the factory without the 220k ohm resistors. I was wondering if I should go ahead and add them while I still have the unit apart. I purchased Caddocks for the repalcements but alas no where to put them without...

Thanks for your thoughts Paul. The subject of the snubber has already been quite discussed.IIRC Romy has turned the whole idea down as uncessary in his context. I am afraid thata snubber may be a sonic move rather than only "engeneering". I'll first ...

...but for a different reason.After lots of traveling I'm finally back and continue my long lasting assault on 834.Pieter kept his word and the nano core transformers (both his MkII and a experimental pairon my yet bigger cores) are here. I removed a...

Romy, how are things progressing with this? Is it all done and dusted yet?
Can you compare and contrast the sonic differences between this high Gm contrivance and your previous EAR 834 variant?
All the World is waiting for the sunrise....

[quote user="guy sergeant"]I used to work for a valve amp making company and we had a little 2 stage phono amp that sounded far better than the 834 with passive eq, no feedback etc. It also cost less than the EAR.I can send you the schematic if you w...

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...
