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.
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.
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.
