THE PLANETS  phono amplifier



Level 4 Phono amplifier .

The main unit with power supply of 2 unit design. 

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

It uses ECC83 tube not-NFB input stage, CR type Curve EQ ( six kind Eq curve ), 5687WB with Hasimoto line output transformer output stage( with XLR and RCA output).

The The Planets 's application of a highly efficient solid-state voltage regulator with EZ80 Tube for current regulator and Hasimoto choke in the HVB+ power supply . Also it use the external power supply get highest S/N.

The MC step-up transformer use Hasimoto HM-X ( made in Japan )

The Planets 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 )
