stereo yamaha pioneer b&w

This is what i know of it ..cd player works well ..amp switches on but there isnt that heavy thud a couple of secs after you switch it on hence i think small issue with amp that someone who knows something about them could sort .. 1 speaker works 1 doesnt ,it was fixed under warranty shortly after first being bought well over 12 yrs ago but within couple of wks went the same way again . So basically my dad had tinitus anyway and could only hear in mono so was happy enough with one speaker working., when it stopped working i just went out and bought another stereo after a few hrs of fiddling around with different wires on back of amp cus i thought might be a connection fault , not much knoledge of electronics so gave up on it .. I can see the seconds and minutes going up on the cd player , and tbf the amp was becoming a bit intermittent few wks before system stopped working ..So its gotta be an amp issue. Cracking sound out of it even with only one speaker .

Thats ultimately alls i can tell you of it..barr i can say it just needs someone who knows exactly how these things work to get amp and 2nd soeaker up and running ..
Needs collecting ..spots of dirt on facia from dog shaking his winter dirt off ..Goodboy Il have it damp clothed wiped.

ALSO AN AV RECIEVER SUBWOOFER SET UP IN MY ADDS IM TRYING TO OFFLOAD CUS I DONT NEED IT ..Had 1 yrs mild old man use and put into storage for 10 yrs ..all was bought from new and had one old man owner.
