[net.audio] Modifications to mid-fi amp

sarees@watlion.UUCP (Steve Rees) (07/26/86)

I'm new to the net, and have recently finished scanning the last 200 or
so messages.  I'm very impressed with most of what I read (esp. the 9-part
series on audioPHILe's system. )  What I want to do now is solicit suggestions
as to the best (relatively easy) mods to make to my somewhat elderly
Sansui integrated amp (TU-777A).  (i.e. what portions of the circuit 
(pre-amp? power-amp? PSU?), what type of changes, what type of parts 
to use (polyester caps? polystyrene caps?  mylar?) ).  General guidelines 
would be very helpful.  I have a complete schematic, so I should be 
able to figure out how to implement your suggestions.

Thanks in advance,

If the amp is more than 10 years old, I would suggest starting out
by replacing every electrolytic capacitor in it.  They deteriorate.
