Smile Power amp fault-any suggestions please?

Hi all, this is my first post on this forum. I have been given a SoundLab SP6 stereo power amp but it has a fault. One of the channel outputs sounds fine but the other channel is barely audible-any suggestions as to what might be the fault?
Many thanks

Could be anything from a faulty pot to blown output fuse. You'd need to open it up and do some testing.

Checked fuses by the capacitors and checked for burnt areas on pcb upperside but i am no expert here. Probably a job for a pro. Trouble is electronic engineers in Hereford are as rare as hens teeth. Thanks anyway

It really needs an audio tech to look at it as they will have the circuit diagrams and have experience of fault finding. Is risking death really worth it for a few quid ?

Maybe worth a purchase, fix yours with the help of the working one, then have two or re-sell!!
