General:
One of our favorite vintage preamps from Sony and super rare version omitting the "D" from the TA-E77ESD by removal of the outdated DAC portion.

Full of great features including a very capable phono section that can accommodate both MM (Moving-Magnet) and MC (Moving-Coil) phono cartridges for your turntable.

Please note the wood side panels are very high quality, but may be reproductions.

Brand background:
This is from the golden era of Sony when they built the best components.

Ownership:
Unknown ownership history.

Amplifier recommendations:
Both solid state and tube should pair well with this unit. We recommend a Sony from the same period like a TA-N77ES.

Connections:
9 sets of RCA inputs and 2 sets of outputs for connecting just about anything you have.

General sound:
Typical 1980's solid state with very low noise floor and full range.

Cosmetic condition:
We rated this a 7 with light signs of use and wear. See our detailed rating scale here.

Working condition, Technical Notes:
Working properly, fully tested in our lab and listening room. 

Included:
Unit and remote.

Packing:
Will be packed using our highly developed in-house process and custom packing materials.  

Specs:
Please see our last photos or the linked owners' manual for full details.

Dimensions & Weight:
18-1/2" W x 5-1/4" H x 14-1/2 Deep, 26lb 11oz.

Age:
Unit was built in the 1990's in Japan.

Reviews:


Also featured on the fabulous Vintage Knob website so you know it's truly something special!

"Available as well, but quite discretely and only in the north-American market as a TA-E77ES, sans "D" : doing away with the S-Video i/o terminals and all digital circuitry but retaining the composite video i/os.

Very very rare version of which I unfortunately have not a single image.

Not counting the big league ESPRIT preamplifiers, the TA-E77ESD was Sony's first preamp since the late 1970s' TA-E7B or TA-E88B. And there never was an ES preamplifier/amplifier combo in Japan, before the 77 combo... or after. The E77ESD is the companion to the TA-N77ES powerhouse."

The SkyFi Testing Process for Preamplifiers:
We start with a visual inspection of all internal components to make sure that there are no signs of heat stress or damage. Capacitors are checked for telltale signs of predictive failure including bulging, shrunken wrappers, or physical leakage. We also inspect the PCBs for discoloration from resistors or transistors that may have been running hot. On vintage units we often spot check select capacitors for value and ESR.

When we first power on a preamplifier we connect its RCA output to a Sencore PA81 Power Analyzer which simulates real world loading conditions and gives us an oscilloscope interface. The first order of business is checking that the volume control works smoothly throughout its entire range with acceptable channel balance. This is accomplished by feeding a 1KHz sine wave into one of the preamp’s line level inputs while monitoring the preamp’s output on an oscilloscope. We then switch to a 1KHz square wave to test the tone controls, loudness function, and filters where applicable. During this step we are watching for equal alteration of the test signal by both channels. This also helps us identify dirty controls that will need treatment. Once the basic line stage functions are verified, we test each input individually. This is especially important for devices that use relays to select their sources. If the preamp is equipped with a phono stage we test that as well. We use an inverse RIAA filter which allows us to feed a reference test signal into the phono input with the proper RIAA equalization and level. A square wave or sine sweep is used to verify that the device’s phono stage is faithfully reproducing the RIAA curve. If the preamp under test has balanced inputs and/or outputs these are tested as well.

We finish up our bench testing with a listening test with our bench amplifier and reference speakers. During this test we check for hum or hiss that may not have shown up in earlier testing. We also check that all of the tone controls and filters perform as expected. If the preamplifier has remote control functions these are also tested. Preamps with tube circuits or complicated power supply topologies are connected at our long term test rig for extended stress testing under real world conditions.
