Hey guys I'm back!
But I never really left as I have literally been using my AU-719 daily since I recapped it around 2013.
I came across a Sansui 8080 in rough shape years ago but am only finally starting to use it due to being able to actually fit this monster it in my new house. It sounds absolutely fantastic! the lyrics really leap out at you and the soundstage is really wide and detailed, this amp sounds too good to sell.
The amp works great except for:
My first priority though is fixing the distortion in the left channel high frequencies.
Any thoughts on what could be causing this? I took it to a repair shop years ago and they couldn't hear it on their (terrible) speakers. My current thinking is it's a transistor on the pre-amp board somewhere that's on it's way out but honestly I don't know anything about transistors so any advice would be very much appreciated.
As I'm not that great of an electrician I was planning on taking a shortcut and purchasing this capacitor kit instead of making a list of capacitors again.
www.audio-high-store.com/product/sansui-8080-upgrade-kit-audio-capacitors/
This kit includes 73 Elna Audio, Nichicon KZ and FG caps not including the two big ones.
Again any advice you have is very very much appreciated, I couldn't have done it l the last time without the advice and generosity of this forum.

The amp works great except for:
- A slight distortion in the high frequencies in the left channel only
- A sloppy bass response and high noise floor likely due to the original aged capacitors
- A lot of surface rust on the chassis and exterior cosmetic damage to the wood case
