I need advice.

Background: I am a devoted music listener for over 50 years.  Most of my knowledge of technology is from the 70's.  
Objective: The best sound quality I can get from my system.
I have numerous amps, turntables and speakers.  The best of these is as follows:
My audio system;  Thorens TD 160 with Stanton 680EEE cartridge, Sansui AU 717, JBL L112
The Sansui (as far as I can tell) is untouched as far as any refurb is concerned. The overall quality of the audio as far as I can tell is good.  But it is what I listen to every day so I have no source for comparison. I have read that an amp that is 30+ years old is due for refurbishment (new caps, etc.).  I have been quoted $350 - 400 for a total refurbishment of the Sansui 717.  I would consider having this work done if it would make a noticeable improvement in the audio quality.  What  can I expect from such an investment?  I welcome any suggestions.

The AU-717 is very capable, but it comes with a laundry list of problems that need to be addressed. I have worked on several of them myself, and they have what is dubbed the "Glue Syndrome". Just google Sansui Glue, and you will see it posted about allot. This stuff eats component leads when it becomes corrosive and even conductive.

The other big issue with the 717  is the filter capacitors are always bad and leaking or starting to leak.

If you can get it completely restored for $350, you better jump on that deal, because I wouldn't do what I do to them for that. I remove all the glue, and replace all offended components. More to it than that, but the glue issue must be dealt with.
