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 ...

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...

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...

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...

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 ...

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 ?

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.

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...

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...

Hi Chris, thanks for the complement. Yes I do try to be flexible. I am contemplating a post grad course in pseudo science at the Massachusetts Institute of Technology. This may help me comprehend some of the recent posts on the forum. 
Animal damage to system
I had a customer whose cat climbed up his gas filled Dayton Wright electrostatic speakers - 12000 volts up its proverbial before the gas got it.Also had a business partner who borrowed some Apogees and let his budgerigar loose which flew into one ...

Richardkrebs - I'm a little disappointed you dont think outside the box, or in this case arm.What about running 2 ET bearings in a T bar configuration, armtube in the middle.You like magnetic dampening but worry about the eddy current. Try standin... 
Triode mode vs pento mode
Atmasphere - I would be interested to know if the design if the output transformer will influence whether one way or other is preferable. With both Air Tight ATM3's ( 6L6's ) and Dynaco MkIII's ( EL34's, 6550's ) I prefer ultralinear to triode. In...

Ct0517 - fyiMagnets can be a little eccentric. On Richardkrebs deck they may prefer the wand end because they get a better view of the cantilever doing her one legged tantric yoga exercises.

Frogman - I used a cupboard door magnet. It had a pair of magnetic plates implanted edge on. You see 2 parallel edges exposed in a plastic case. I placed these on the plinth, under the bearing tube with the edges in line with the bearing tube, nex...
