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.

Fisher 400

Fisher 400 Front

 

If you're into vintage tube receivers then you know this unit is the iconic Fisher 400. Some claim that the 400 is one of the finest tube receivers ever made. Fisher produced them from 1964 up until 1968.

Aesthetically the Fisher 400 looks similar to the 500 and 800 models. Here you can see the Fisher logo of a bird with a musical note in its beak. the face plate is brushed metal and the knobs are brass faced.

There is a head phone jack at the center of the receiver and the infamous Magic Eye tube which indicates the signal strength. If you're interested in how the Magic Eye tube works you should check out the article at AntiqueRadio.org.

Avery Fisher founded Fisher in 1945 and was the dominant producer of hi fi tube gear up through the 1960's. He actually had founded a company before that, in 1938, called Philharmonic Radio. he sold that company in 1945 and started Fisher Radio Company.

 

Fisher 400 Tubes

 

Around 1964 Fisher introduced the 400T which was the first all transistor receiver. But, the hi fi community wasn't really quite ready to make the transition to all solid state so Fisher kept the 400 available until 1968. In 1969 Fisher sold his company to Emerson which then sold it to Sanyo. The quality of the receivers dropped significantly after that. Note the two output transformers and huge power transformer?

 

Fisher 400 Wiring

 

Lots of point to point wiring in these old tube receivers. The selenium rectifiers in these units should be replaced if they haven't been already. Obviously the inner workings are a bit complicated and servicing should probably be left to a professional.

 

Fisher 400 Back

 

Here you can see the four power tubes in the Fisher 400. It uses 7868 tubes in a push-pull configuration while the 500 and 800 series use 8-pin 7591 tubes. Notice the heat shield between the transformers and the tubes. Nothing better to a tube enthusiast then glowing tubes. Well, other than the warm tube sound.

The Fisher 400 is a beautiful receiver that was built with attention to detail and performance. It is highly collectible, as are all of the early Fishers, so they aren't cheap. They don't come close to some of the high priced solid state monsters from the 1970's but as far as tube receivers go they fetch a good price. A fully restored unit can sell for over $1000. An average unit in good working condition will sell fro around $500.
