Sansui AU 719 Restoration Part 2 

Jeff, I don't see a link here.

Good Night, Salavdor. I'm probably not going to be up much longer myself!

@@raygianelli3612 rest a little 😴

You know, I'd heard of that stuff but never used it. Thanks for bringing it up, I'll try it on the next one!

Thanks Andy. Good tip about using noise and an FFT for this task. This is why I always try to read the comments. I'm still learning too!

Thanks! Thing threw me a few curves I didn't mention. First was when I was using a 1/4" headphone adapter, which chose to come apart when I tried to remove it, necessitating the removal of the head jack and disassembly to removed the pieces. Second was the traces on the control board were extremely delicate, much more so than usual even for vintage gear, and 2 eyes detached from their traces. I found and fixed them, but it was not fun.

I used Happich Simichrome polish with buffing cylinders made for cleaning jacks for the telecom industry.

Hi Glenn! Those are Murata RDE5C1H220J0P1H03B, obtained from Mouser.

Ray i also noticed the transformers on your unit are unshielded the ones on mine are shielded your's must have been a earlier model

@@atw4321 I've never seen shielded transformers on a 719, only the 717 or 919. Maybe they put them in later models like you say.
