[yamahacs80]: SH recapping

2011-03-17 by papinje

In the YT video by Gavin regarding rebuilding the SH board, 0.22 polypropylene caps are used with a strict tolerance of 2% . Is such a precision needed for enhancing the performance of this board?

[yamahacs80]: SUB board wrong printing

2011-03-19 by Fernando Zarone

Hello
Replacing all of the caps I experienced a problem: as to one of the two 220 uF caps , the one near -15 V terminals, has the + sign inverted on the board... I replaced it and ... BANG.

Fortunately, no problem seems to have happened.

In the service/schematic manual this cap is not present on the board drawing at all...

Did anyone else noticed this?
