[quote user="Paul S"]Adrian, I wonder how you wound up with the never-mentioned FET 10? I prefer it to the EAR 834 I heard. Is this another case where it's full of old caps? I would not be at all surprised if futzing with those caps might yield as ...

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 ...

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...

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...

[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...

I'm a phono moron, but having had several phono preamps, I think I can understand what finds Romy right in the EAR 834P, which I love. I'm not as skilled and crazy as to try to make all the Thorsten mods in it by myself, but I've tried some tube swap...

I am happy to have this here. I hope our members will take advantage of this and fill it up with information. I certainly will note any surprising observations I have with EAR 834 if I modify it. It seems more like a general catalog of elements,...
