Venus  valve tube MC/MM phono amplifier



Level 3  valve tube MC/MM  phono amplifier .

The main unit with power supply of 2 unit design. 

Venus use CR type EQ curve design, the CR Type is good method for revive EQ curve ( not-NFB).

It uses ECC83 tube Class A and not-NFB input stage, CR type Curve EQ ( six kind Eq curve ), ECC81 and E88CC tubes Class A and not-NFB output stage 

The Venus 's application of a highly efficient solid-state voltage regulator with 6X4 Tube for current regulator and R-Core ( Japan Hi-B core ) choke in the HVB+ power supply . Also it use the external power supply get highest S/N.

 

Features  

 

Mercury has a select control for select 6 kind EQ curve : 
RIAA , Londo , LP , CCIR , AES , NAB .

RIAA, match 99% LP. ( 1955 after )

Londo , LP , CCIR , AES , NAB  are other curve for old LP. ( 1955 before )
