Sony STR-7055

Sony STR-7055

The Sony STR-7055 was made from 1972 until 1976. It has great clean and classic styling and looks especially good with the wood case. It was near top of the line with only the STR-7065 above it.  It really looks nice when lit up as well. There was also an STR-7055A model that was made later in the production run around 1976-1978. No one really seems to know the difference between the two models.

As you can see it has large heatsinks that protrude out the back of the receiver.  It also has connections for three sets of speakers. Overall this is a very good receiver. Sony made quite a few of them so they are somewhat common. It puts out 55 watts per channel into 4 ohms and weighs in at about 34 pounds.

The Sony STR-7055 will sell from $100.00 to over $200.00. One recently sold for $140.00 that was in great shape and worked perfectly (9-30-2011).  The one pictured here was mine and it sold for $77.00. It was also in good condition with just some minor wear to the edges of the wood case. Everything worked properly. If you have a chance to pick one of these up at a decent price do so. They are great receivers.

  1. this is beautiful. am looking for this exact receiver. i bought mine in 1973 and it died. am looking to replace. would you have a lead on where i might find one in excellent working condition as i will use it every day…

    1. They are very nice looking receivers. I just sold this one last month. They pop up on ebay once in a while so if you’re patient you should be able to find one in nice working condition. The STR-7065 is very similar.

  2. I have one in Ottawa if you pay shipping you can have it for $135. It is mint and needs only a cleaning. * Note: Does not have the wood and the metal is flawless.

  3. I own a 7065A which I purchased off ebay a few years ago. It’s stock and in mint condition. The ‘A’ version of the 7065 has an improved tuner section. That goes for the 7055 as well. The ‘A’ version uses a better phase lock loop in the tuner thereby decreasing THD and increasing stereo separation in the FM tuner section. The 7065 also had a power resistor in the back left corner of the receiver that use to get quite
    warm. The ‘A’ version does not.

  4. This receiver and the whole STR-70×5 series is a feeble semblance to what Sony receivers used to be, from 60×0 through 60×5 series. The design has few serious layout faults, such as bad grounding technique for instance, therefore may hear some background hum (ground loop!). Get yourself ANY of the 60×0, 60×5, 6120 or 6200 and you will be impressed of quality and sound. Not this one.

  5. Have a 7055A – been running great for years – NO serious flaws as someone stated. Have had the vintage bug and been thru almost everything out there – Luxman-Marantz-Pioneer-Sansui and still have this 7055A so that says something and Iam mostly a Sansui guy. These have excellent soundstage the bass-mids-highs are just perfect. With a good set of speakers this is a receiver to really appreciate – quality build and being a tech also these are very easy to recap – I’d also change out all those uni-watt transistors in the driver although mine were fine they can be leaky down the road. Really just an all round fantastic receiver with enough power to drive most any set of speakers.

    1. Thanks for sharing. I’m looking at a 7055. Comes with original cardboard packaging and has just been cleaned by an audiophile shop.
