Sony STR-6065

Description

Welcome to the world of finest stereo reproduction. The Sony STR-6065 consists of excellent FM and AM tuners, a clear preamplifier and a powerful output amplifier in one complete package.

Off the air FM stereo and AM programs, records, tapes, or any other program sources can be channelled through the STR-6065.

Speaker terminals for main and remote speaker systems, and the additional centre channel output allow for the future expansion of your stereo system.

In the FM tuner section the FET front end raises the sensitivity to its theoretical limit while retaining the ability to handle strong local stations without overload and spurious response. Solid state filters in the IF section replace conventional tuned IF transformers for exceptional selectivity and long-term stability. Station on nearby channels do not break through into the program you're listening to. The receiver never needs realignment.

In the AM section, the STR-6065 also provides high sensitivity with superior signal-to-noise ratio, and its linearity and dynamic range assure low distortion. This remarkable improvement of AM sound is the result of the FET input circuit and solid state IF filters.

Precision tuning is easy with the long, linear scale and accurate tuning meter.

An effective muting circuit silences all inter-station noise as you tune from station to station. This protects the speakers and further simplifies tuning.

The amplifier section has all the power needed to provide any speaker system with plenty of reserve for difficult passages. It reproduces the entire audio range without permitting the slightest trace of distortion to intrude upon the performance.

The connection and the operation of the STR-6065 is quite simple, yet provides considerable versatility.

Maybe the most underrated vintage receiver. Bass goes really deep with clarity and detail all across. Kind of upfront in your face sound but not fatiguing at all. Beats Marantz 2270, comparable sound to Yamaha CR-1000 without the power overkill. Look for damping factor 60+ in early 1970s gear. Still have Sansui Eight from the same period to test and compare. If someone had both please comment. But for the price of one Sansui Eight you can have four of these.

Optisch eine Legende. Schalter und Knöpfe für die Ewigkeit. Vielfältige Einstellmöglichkeiten. Schöner, druckvoller Sound. Warme Stimmen. Transparenz hervorragend.

re: STR-6065

Service manual was/is a great help to fixing my 6065. 3 things I fixed :

1) 120Vac Return (R) ac line (white) going to the transformer was being squeezed by the transformer metal case to chassis ground (still operating fine, though) - placed said wire accordingly inside case to remove short. This seemed to quiet the background amp hiss between songs.

2) Removed R904 (1 Mohm 1/2W resistor) since it was putting 120Vac (albeit only 0.12mAac - even with power OFF !!) on the Chassis via the Hot (H) ac line (green) to power switch. This situation blew my soundcard when I plugged the speaker out 1/8" o/p to the AUX in front jack (floating at 120Vac). This mod was OK to do since I already replaced my non-polarized AC mains plug/wire with a polarized AC mains plug/wire (return prong wider than the hot prong).

3) Some electrolytic caps were replaced on the main amp (including i/p coupling ecaps with higher capacitance Wima caps for more bass). All ecaps were replaced on the equalizer board (including i/p couplling ecaps with higher capacitance Wima caps).

Sound is so much clearer now with a much wider soundstage - like I lifted a heavy blanket from the speakers !!

P.S.: Just one thing : Pages 46 and 47 are missing from the service manual (tone amp details).

My Dad's Sony STR 6065

A couple of years ago I cleaned out my late parent's home and I decided to bring back Dad's Sony receiver, double cassette tape deck and CD player. I unpacked it and hooked it up to the CD player and checked it out. Outstanding! Better yet I found your website and there was the lost manual! Thanks so much, you have enhanced the sentimental value of Dad's treasured unit. He bought it in '71 and used it right up to the end in 2009. Thanks again!

re: My Dad's Sony STR 6065

Love this unit. Mine beloved 6065 just succumbed to a lightening storm on 23/April along with my computer and TV even though plugged into a APC protector. I am going to get another receiver but am hoping I can find some way to bring the Sony back to life. Have not put a meter to it yet but plan on checking the transformer and capacitors first and go from there.

Any suggestions? would be appreciated. My wife and I got this in '72. She is passed but the Sony lived on.
