Anyone try the replica B-60 Fidelity Research VTA?

My sammle moved not only up an down but also sidewards.
The reason as far as I can judge is the pin on the screw
which connect the inner and the outer collar. The inner collar
slides along this pin up and down but if there is
any play between this pin and the notch of the inner collar
the tonearm will move also sidewards. This means that the
'replica' is not as 'exact' as claimed by the producer.
I assume that this screw is better made by the orginal B-60 .

Well I am glad with any contribution but so far only Lew and I wrote about the replica. To summarize: he is satisfy with its functionality and has only some small esthetical problem with the (sticky) siicon oil while my only problem is this damn screw. But what about Thekong's sample, irrespective if its 'fabricator' is from Taiwan or Hong Kong?
Dear Dover, It was wise from me to first check the price of the new B-60 before ordedring one. What is the price per liter of your Holly Water?

Dover, thanks for the explanation. Will be in touch with you very soon.

Dear JCarr, Touche'. The problem with my statement is that it was general and followed Audpulse's specific comment about a 47K load on an MC. Are you suggesting that the load resistor never has any impact on frequency response of an MC? If so, teach me. I thought that very low values of load resistor (i.e., high loads) can dampen the HF response, of some MCs in some cases with some loads. So if I am correct, then perhaps there should be an industry-standard ratio of load resistance to cartridge internal resistance, for published tests. Anyway, who ever publishes curves these days, for cartridges? Even S'phile takes the subjective judgment of its reviewers as gospel.

My main point was that unless the load resistor is much closer in value to the internal resistance of the MC cartridge (where 47K would of course be maybe more than 1000X the internal resistance and could have no effect at all on gain), or certainly if it's less than the internal resistance, it will not have an appreciable effect on gain.

Ugghh! Syntax (the linguistic, not the person) is my bete noir today. In my second paragraph above, I mean to say that the load resistor can affect gain if it's value approaches, equals, or is less than that of the cartridge.

Hi Lew: Since I have already written about this topic on the What's best forum, and a kind soul there was willing to convert my charts into gifs, I recommend that you read the following thread on the SME 30/2 turntable, from pages 3 to the end. The charts are on page 6, and they will show you what kinds of frequencies are affected when the load resistor value is changed.
