Sony STR-7045


This very nice looking Sony STR-7045 was made available around 1973 or 1974. It retailed for $370 which is over $1800.00 in today’s dollars. So, it wasn’t cheap. It puts out 30 watts per channel and is known for its selective 4 gang tuning section.

This was the typical look for Sony’s STR-70XX line with a silver face, black dial face and wood cabinet. The STR-7045 was the middle of the road receiver while the STR-7015 was the entry level offering and the STR-7065 the TOTL. The previous generation was the STR-60XX series. While the Sansui, Marantz, and Pioneer receivers were a little more flamboyant with their knobs, lights and meters, the Sony had a more simplistic look to it. But, it made up for the lack of frill with just plain good performance and quality construction.


Sony STR-7045 Inside


The Sony receivers were very well built and rarely required servicing. The STR-7045 is all discrete with the exception of some of the FM section. The preamp/power amp sections are all discrete as well. It was the last generation of Sony gear that was discrete as later generations had a lower component count, through the use of IC-based circuits, which reduced the cost of production.


Sony STR-7045 Inputs


The Sony STR-7045, and Sony STR-70XX series receivers in general, aren’t nearly as popular now as the Marantz, Sansui and Pioneer receivers of the same era. This is reflected in their price. The STR-7045 sells for around $125 in very good working condition. The top of the line STR-7065 sells for about $200. As a comparison the Marantz 2230 (30 watts per channel) sells for about $400. The Sony receivers are good quality stereo’s though, so if you want performance at a lower price, then take a look at the STR-70XX series line.

One thought on “Sony STR-7045

  1. First, thank you for your dedication to this website.
    I have both the 7045 & 7055 series and in terms of sound signature it can be best described as “rounded” with a tad bit more emphasis on bass (has more than my Marantz 2500 & Realistic 2100) with excellent top end sparkle. Also both receivers also holds onto the note a micro second longer than other receivers. Meaning it takes it’s time with he music while others are faster & tighter.
    I can listen to these for hours without fatigue.
