Sony 3120a Amplifier

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.

Akai 4000DB Reel to Reel

This Arrived some time ago and I hadn't had the chance to run it through its paces.
 I have some excellent Columbia recordings of Leonard Bernstein originals. If your testing these old reel to reels I find piano and Symphony ensembles are an excellent, discriminating source for any fluctuation or unwanted noise.

This 4000DB is an attractively designed compact tape deck offering multiple connections and controls and quality features among which are Akai's one micron gap heads for high density recording and the well known the incorporation of Dolby Noise Reduction System.
As you can see the Akai's one-micron gap head is responsible for an amazingly important difference in tape recording. It's the difference between ordinary performance and high density quality recording and playback. Ordinary head gaps are from 2 to 4 microns, but the gap of this outstanding head is only one micron. This high density recording system provides excellent frequency response and clear, high pitched sound is generated as a frequency tone and recorded smoothly without distortion.

With the Dolby Noise Reduction System, hissing noise heretofore thought impossible to eliminate, is reduced to a completely inaudible level. Basically, this circuit boosts the low level signals prior to recording and lowers them by precisely that same amount at playback time. During this revolutionary process, the extraneous noise is eliminated, thus also eliminating tape hiss.

Internally illuminated and quite cool are the  VU Meters

In keeping with Akai's top quality parts utilization policy, the 4000DB also features robust construction and sturdy mechanism. Further, a highly efficient induction type motor assures stable tape travel and ideal starting torque. The characteristics of this motor coupled with a boldly designed flywheel reduces wow and flutter significantly.

Circa 1969 this Gem is the heart of my listening pleasure. I mean what is more gratifying than hitting the switch of an audiophile unit like this knowing it has served for 40 years and is still today precise and so musical sounding! I hope you enjoy my images.
