Re: [TenTec] Quite PWR SUPPLY?

["Paul S. Serio" <pss@tecinfo.com>]

No noise from my Astron RS-35M. Quiet as a church mouse. Is there a 
possibility
that the surface you have it sitting on is resonant at 60 hertz? I 
remember in the days
of high fidelity turntables that feedback could be introduced by 
mounting the turntable
in a low frequency resonant position in the listening room. Attempts to 
reduce the
feedback were foam fads on top of the platter (to decouple the energy 
before the
cartridge picked it up) or similar devices on the feet of the turntable. 
Experimentation
with placement might be all that is required. Just a few thoughts for 
what they are
worth.
