output transistors for sx450

I replaced 2/4 broken amplifier transistiors
replaced all Elkos
Sound on headphone is fine
Signal on Speaker breaks down under load (after switching to Speakers)

(yellow=Input)
(red=Speaker Output)

The Input Signal does not Change - it seems to be a different scale

Welcome to AK.. Probably be best to start your own thread. I'd say your broken amplifier is still ....Broken..
