3 Years! My follow-up is lacking.

Yes, I did manage to tap the circuitry to make a pre-out on my SA-GX505 receiver. The following links were very helpful in figuring it all out:

Commentary on why the SVI 3206 eventually fails in this receiver:

SVI 3206 pinout, linked from the above page:

The site where the pinout diagram originated:

And here is my handiwork:
http://www.colp.ca/projects_technicspreamp.html

The connection is very simple. I first removed the SVI 3206 module. After confirming that pins 13 and 15 were the right pins, I wired some RCA jacks to the spots where input pins 13 & 15 go. I hooked my grounds to jumper J609, which is signal ground, conveniently located just forward of the SVI module pins.

This receiver and my gainclone amp make a good pair.

EDIT : OOOPS... I didn't notice this is such and old thread. I HATE THAT!!!



I see you've already acquired your heatsinks, but as a fellow
bargain hunter, I found a pretty nice deal on ebay that you
might want to consider. You know, for future projects and such.

Aluminum Heat Sink 3 13/16" x 2 3/4" x 1"
Buy-it-now price : US $1.00
Quantity available : 100
Item location : Oxford, Alabama, United States
Ships to : Worldwide

I'm not affiliated in any way with this vendor, but I have purchased
these heatsinks from him before. The quality is excellent, and
for this price it's too good a bargain to pass up.
