Has anyone used the Lafayette service manual procedures for aligning SQ-W decoder, and has the results matched what the manual says?
Seems detail is a bit thin.

They actually look in good condition, may be the large one nearest the lower rotary switch isn't (a bit of brown gunk on its top), if they've seriously gone bad they're normally puffed up at the top and lots of gunk. If you're getting no output from any channel it'll most probably be the power supply.I just received an SQ-W from Japan which I won for 1yen. It powers on but there is nothing from the main outputs or rec. out. I left it powered on for several hours no change and all the capacitors still feel cold to the touch, it was sold as "junk" so I expected problems but it still looks pretty clean inside. Should I just start replacing the blue caps? Suggestions welcome, thanks.

For the power supplies you won't get film caps with the same Capacitance value as the ElectrolyticsThank you everyone for your replies.
In regards to changing out the large caps on the EPO-193 board, would there benefit to using some film capacitors or be best to stick with electrolytic caps?
Thanks
Use 'lytics for the p.s. and film for the restThank you everyone for your replies.
