Sugden Masterclass Monos

[HR100MCS]

Help!!!!!!!!!!!!!!!!!

Last night my hi-fi was superb, everything I expect and more.

Tonight my hi-fi is terrible. Turns out that one of my Sugden Monoblocks apperars to be distorting badly. Any ideas? Do I need to take it back to Sugden? Why????? One minute A-OK now distorting. Why me

Double check all your wiring first, and then swap over channels on sources pre and speakers.
