[sdiy] noise with vintage equipment

[Graham Atkins]

You're not providing much information are you ? . What do you mean by  
"19" noise
reducer" ?, are you talking mains noise filtration ?. Have you  
listened to another 310
for comparison ?. You don't even say what sort of noise, it could be a  
grounding
(hum loop) problem or many things. It could even be "beehive noise"  
from the various
dividers following the top octave generator if this is part of the  
design.

You should be asking if anyone is familiar with the Eminent and do  
they know of any known faults that
may affect the output.
