Information from Leben Website

RS-30EQ is equipped 
with the CR-type equalizer based on GE(General Electric/USA) 12AT7 authorized 
by J.A.N.(Joint Army & Navy) standard of the US Army, and can reproduce a 
very high quality and clear sound without adding any NFB.  To avoid 
compromising sound quality using the NFB type, one of the solutions we adapted 
to completely protect the sensitive CR type equalizer was to originally develop 
for RS-30EQ a high quality "Orient-Core" power transformer perfectly 
shielded to shut-down hum noise from the transformer perfectly.

We have also selected the finest available high-end audio components to keep 
the deflection of the RIAA curve below +/-0.2%.
