Just Arrived is this rare and collectable Sony amplifier. This is the "a" model which offers a response of 180Khz compared to the 3120 which has a 100Khz response. It also boasted improved THD specs.
The cosmetic difference? There is no "safety" LED on the front next the power light on the "a" model. I have, as regular readers know, the Sony TA2000 preamplifier which is considered as pure as they came in 1967 and still today holds its own against many Solid State units. This 3120a was one that was paired with the TA2000. At 50wpc and a THD of less than 0.03% it literally jumps my vinyl out of the speakers. I recommend this setup for anyone collecting rare solid state. It is a pleasure to listen to it's pure Sony Vintage Sound.
Vintage Sony units truly define an era.
These 70's modules are by far trend setters of their day.
Here is a somewhat rare cassette Dolby B noise reduction unit from that era. Not to be confused with Thomas Dolby although he was equally innovative! Remember, "poetry in motion" moog music! Interesting fact... He won an achievement award 1998 for Internet music downloads. Interesting because his hits were prior to Internet down loadable content.
Back to Dolby Labs gem...
It is encased in a true wood cabinet and sports the two massive VU meters so characteristic of the day.
This is a museum quality piece that should be appreciated.
Here are some specs
Built-in Headphone Jack
Two Mic Input Jacks
Two Professional VU Meters
Two-position Mic Attenuator Switch-reduces level of input to minimize input distortion
Tape/Source Monitor Switch
Built-in 19 kHz Filter Switch-eliminates FM multiplex interference
Two Playback Volume Controls - Ultra cool
Two Record Level Controls
Built-in 400 Hz Oscillator for input/output balancing.
Bravo Sony!
