| VPI cartridge install f/phase inverting pre 04-03-13: MofimadnessI've never seen or heard of a preamp with a built-in phono stage, where ONLY the phono stage inverts phase? Usually it's all or none, but maybe they do exist?This is very common in older tube preamps, each 1/2 tube gain stage... | |
| VPI cartridge install f/phase inverting pre BEWARE you have to check whether your phono or line stage invert phase. If the line stage inverts then change the phase on the speaker cables. If the phono inverts phase then you need to change the cartridge leads otherwise your other sources will... | |
| Eminent Technology ET-2 Tonearm Owners Hi RichardkrebsHad a very good Easter beak, very relaxing. Thank you for asking.Was wondering, now that you know how the ET2 works, whether you had found time over the long Easter break to remove the lead from your arm, put the decoupling spring b... | |
| Eminent Technology ET-2 Tonearm Owners Chris/Slaw - At the time I tried the van den hul the arm was mounted on a Roksan Xerxes. I was using a Shure V15Vmr so that could have been a contributing factor for picking up RF due to the higher impedance than a MC. Having said that, with litz ... | |
| Eminent Technology ET-2 Tonearm Owners Richardkrebs re your last post. I believe we have something in common. In the contract work I specialise in I too am totally indispensable. Not only dozens but hundreds of employees world wide depend on my expertise. One mistake and a company coul... | |
| Eminent Technology ET-2 Tonearm Owners Hi Slaw,The arm wand and bearing tube are ungrounded. I tried grounding the aluminium arm wand but couldn't hear any difference. I had a major problem with RF when using van den hul monocrystal silver wire, and went back to a stranded copper litz ... | |
| Eminent Technology ET-2 Tonearm Owners RichardkrebsFurther to the above, you conceded that after 25 years of owning and modifying your ET2, you did not understand how the I beam decoupling system worked until recently: 03-19-13: RichardkrebsIt could be that tuning here with springs and... | |
| Eminent Technology ET-2 Tonearm Owners Richardkrebs - So predictable. Yes there may be other brilliant designs, but the discussion is about the ET2, in case you've forgotten.Yet again you just dont understand the physics.You are trying to turn the ET2 into a home brew Kuzma, Rockport, ... | |
| Eminent Technology ET-2 Tonearm Owners Chris - thanks - no war down here. My motivation is to help people set their systems up correctly and learn more. We all learn from shared experiences. The debate over the past 7-8 weeks could have been much shorter had it not been inundated with ... | |
| Eminent Technology ET-2 Tonearm Owners Chris, your diligent follow up with Bruce Thigpen is much appreciated: If the weight is coupled the system resonant frequency would be extremely low, a resonant frequency at 3Hz with a significant rise in response (6-12dB) results, which would aff... | |
| Eminent Technology ET-2 Tonearm Owners Thekong - yes you are correct. That "rebound" as you call it has a resonance. The idea behind the variable spring rate and shifting the position of the lead counterweight is to place that resonance below the horizontal resonance of the arm so that... | |
| Eminent Technology ET-2 Tonearm Owners Richardkrebs:Yet again I have to address your gross assumptions and misunderstanding of the principles of the ET. RichardkrebsFrogman and Dover say that they prefer a loose connenction and one leaf spring. Chris says that triple springs produce a ... | |
| Eminent Technology ET-2 Tonearm Owners Frogman, Thanks for the positive feedback. With regard to the loosened I beam this is where I got to:When I first imported the ET2 the spring was prone to coming off. If I recall correctly there used to be a little piece of dampening stuck to the ... | |
| Eminent Technology ET-2 Tonearm Owners Richardkrebs Astounding!After 25 years of tinkering with your ET2 tone arm, you now reveal in your recent posts that you have only just worked out how the arm works.Only now have you realized that the sprung I beam has a resonance and the tuning o... | |
| Eminent Technology ET-2 Tonearm Owners Chris - I assume you know the driving dogs are Kiwis ? NZSPA trained no less, here in Auckland. Not sure if they run ET's, but they demonstrate the benefits of high compliance.At the Engineering faculty I also remember Dr Fassbender, who had a fet... |
