    I think (going from memory, will have to check to be sure) you can wire from that solder blob (next to the R) to the first VIA (hole) between the chip pad on the left in that pic, it will need some scraping to expose the copper

    Stick your meter on that first hole (inside that white rectangle between pin3 and 4) to see if it measures continuity to the Rout socket pin

    Yippee! STEREO



    I decided to scrape off the screen around the pins and it became obvious where everything should go.

    Leo you are a life saver!

    C25 is the only place I'd recommend a 10uf tant as that cap is quite critical, it needs to be low leakage, of course some electrolytics may be better but tend to be more leaky , its something you just have to experiment with

    I tend not to post fit this type of cap here and this type there mainly because my external regulated psu is nothing like the supplied unit so results would vary, what sounds good with mine may be crap with the standard one
    Which PSU are you using, if you don't mind me asking?

    I too had problems with lifting tracks. Ended up with a piece of wire from input cap to chip pin.
    It's the first time i've had to work with surface mounts, so i'm not exactly an expert.
    All good fun though.
