Pioneer SX780, replace both STK-0050
This Pioneer receiver is out one channel... this was a fun project, and these pioneers are so easy to work on, I like that the service manuals is at your fingertips.... be extra careful around these power packs (STK'S) when or if your taking measurements...you don't want to short them out as it's hard to come by... I would like to thank Tim Corner for giving me these power packs, He upgraded with the new modules STK's on his SX-780 and I was able to use them in this receiver and saved it from the trash.... if you enjoy this video, PLS subscribe to my channel for more repair videos ..
