Who needs a MM cartridge type when we have MC? Heaps of Ruby/diamond/Sapphire/Boron cantilevered cartridges available in the 80's, probably more than today.Sumiko Talisman Boron, Sumiko Talisman Sapphire sold in the 1000's/Kiseki Sapphire/Zenn Ruby/Dynavector Ruby & Diamond to name a few.C... | |
A Copernican View of the Turntable System Halcro - The easy way for you to fix the issue is to get 3 holes cut and threaded for machine screws ( grub style ) around the outside of the centre bolt in the arm board as wide as possible ( maybe just inside the edge of the tower. Get some mach... | |
Eminent Technology ET-2 Tonearm Owners Chris, the good thing is, if we have a bad day over here we can fly over to your place and start the day again ... | |
Who needs a MM cartridge type when we have MC? Nandric - I think you are right. The different cantilevers have different characteristics in terms of stiffness, natural dampening and resonance. I suspect that putting ruby cantilevers for example in a cartridge that hasn't been designed for it i... | |
A Copernican View of the Turntable System Hi Henry,I've mentioned the issue of incongruity between platter and armboard a number of times, but it seemed to fall on deaf ears. Your experience matches mine when I had the shop. Since most folk level their platter and assume everyone else is ... | |
Eminent Technology ET-2 Tonearm Owners Chris - No I dont have the equipment, but Martin Colloms did in a Hifi News review years ago ( 1985, I think ). He measured the resonances before and after the air bearing and compared them to ascertain how the air bearing dealt with such. Typical... | |
Who needs a MM cartridge type when we have MC? Timeltel - You should be able to convince someone to pay an extraordinary sum of money for the HA-1000. The value proposition would be - "For the princely sum of $1000 someone will learn never to invest in old solid state gear. The future savings ... | |
Eminent Technology ET-2 Tonearm Owners Hi Frogman,Thanks for the feedback. You have highlighted the nub of the issue in your last few sentences - when the arm moves laterally to accommodate eccentric records it becomes very complex. In addition to the bearing tube moving back and forth... | |
Eminent Technology ET-2 Tonearm Owners Hi Chris - Yes I have a good memory. When we first imported a pile of ET2's we had in the shop an ET1. There was a big debate at the time that the ET2 had less bottom end than the ET1. The ET1 has a fixed counterweight. My business partner preferr... | |
Eminent Technology ET-2 Tonearm Owners Richardkrebspara 1 - not obvious to everyone. You are testing the effect of magnetic damping with an ET2 with rigid counterweight and high mass. Chris has been testing magnetic damping with partially decoupled counterweight and no added mass as ha... | |
Eminent Technology ET-2 Tonearm Owners Richardkrebs,I have finished testing Dover's mag configuration on my modified ET2For the record you have NOT tested my ( Dover's ) configuration at all.You have only tested magnetic dampening in the context of your own reconfigured version of the ... | |
Eminent Technology ET-2 Tonearm Owners Chris - Thanks for the feedback. I always thought shagging around with the system was housework. Out of interest do you run your Verdier with or without the ball inserted ? | |
Eminent Technology ET-2 Tonearm Owners Chris - since I am not running the ET at present, would be good if you could test the eddy current clamp I describe in the above post, using 2 magnets clamping the tube at one point in "S-N Beam N-S" configuration. | |
Eminent Technology ET-2 Tonearm Owners Yeah I got all that the first time. We'll never agree on the added mass approach. But anyone trying it should check their cantilever deflection on eccentric records to ensure the cartridge can cope.I'm sceptical on the degree of movement in the be... | |
Eminent Technology ET-2 Tonearm Owners RichardkrebsThou doth protest too much, methinks About what exactly. You raised the issue of bearing stability and the placement of magnets. The mass you have added to the bearing tube destabilizes the air bearing. My question to you as to whether... |
