Braço Magnepan, UNITRAC 1

Braço  Magnepan, UNITRAC  1

Pois para quem estiver interessado, apareceu este no eBay, um bocado avacalhado em relação aos intocados de origem mas quem sabe, pelo preço, aceitável (?...)!? ...

http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=321348164357&fromMakeTrack=true&ssPageName=VIP:watchlink:top:en

E como vem da Europa não tem sobrecustos de Alfândega! ...

É o primeiro que vejo no eBay nestes últimos seis meses!!!

Excerto de uma entrevista dada pelo falecido dono da Magnepan e projectista do braço à Stereophile:

Lander: The only Magnepan product that hasn't been a speaker was the Unitrac tonearm. Why a tonearm?

Winey: Because I'd come to feel it was the weak link in the whole system. I had an idea: a unipivot with no damping. One of the problems I've always had with tonearms was their damping. It's a catch-22 situation because, if you have a turntable that's on a surface that does some vibrating, damping probably helps. But it's a Band-Aid; you're better off without it if you don't have to use it. The dynamics are far better, and the tracing of that groove is more accurate.

Lander: How long did it take you to develop the Unitrac?

Winey: I started thinking about it in the late '70s, but it took five years to get into production—a real big job, let me tell you. We had local machine builders build parts, and we assembled them. One of the things I felt was a problem with most tonearms was inertia, which I got around by placing the pivot point approximately a quarter of an inch from the counterweight's center of gravity. It had a very simple means of adjusting anti-skate, and it had a vertical-tracking adjustment. The price was right; it was only $325. It went over very well. We sold almost 10,000 of them in four, five years. But by the time we got it into production, the CD was coming down the railroad track.

Amigo António. Não digo (nem posso porque não conheço) que o braço não seja absolutamente fabuloso. Só digo que com 8g de massa especifica, não é para mim de certeza e limita bastante na escolha das células.

Está neste momento um no eBay.co.uk, o segundo que aparece quase completo de palamenta, desde Setembro passado, que eu tenho andado de olho neles!? ...

Está no limite do barato para o carote(?),  mas já vi nas lojas pedirem 1000€, está a 499usd, pode ser uma opção muito interessante para quem o compre num sítio onde não haja Alfândegas (atenção MicroGruas!?...)! ...


Tem os protactors, aquelas fichas verdes da Amphenol (hoje em dia 100% desaparecidas) e o pente de cabos de ligaçao à célula ( raros e escassos e que podem sózinhos valer 50/70€...) e à primeira vista o essencial!? ...

Eu não vou porque seria o 4º e vindo dos States ia apanhar +/- 140€  de despacho!...
