    I didn't know that - I have a Breuer Dynamic arm (the Type 5A), and I have often thought about fitting a Decca cartridge to it, though I don't think it would be possible to use the GB mounting block with the Breuer.

    Herr Breuer's designs were the inspiration for other arms: Tom Fletcher's 'Sumiko "The Arm"' is one example, and possibly the Linn 'Ittok' as well.

    I will do. The zeta is one of the greatest tonearms - its form is still being copied today - testament to its fundamental quality

    Mick admired the sensible quality engineering of the breuer - as for using the GB clamp in one - probably not as it may not fit the head shell....

    interestingly, the original Zeta prototypes were developed and listened to using an LP12 -Mick discarded this (he gave it to his daughter -who still uses it...) when he realised the Sondek wasnt up to the task! other equipment used in the arms development were a big 70s pioneer amp, a prototype mission 777 power amp, various valve amps and a ARC Sp8, also japanese direct drives (a luxman PD555 was involved) and lots of colleagues ears...every change to the bearings,bearing yoke, type of aluminum used, the finger lift etc all carefully listened to using mostly heavy rock music and prog rock - especially Gentle Giant and Tull!!


    the lessons learned from the Zeta, informed the design and manufacture of the Mission Mechanic -ie entirely machined HE30 aluminum from one billet - smaller bearing yoke, no finger lift on headshell etc

    swap the plugs over and the problem switches channel.

    That, or the other end of the chain.

    Sounds like a fault with the Zeta then.

    really? even with continuity from the tags to the phono plugs?

    Try another cartridge?
    It is impossible for anything digital to sound analogue, because it isn't analogue!
