Turn the central heating up full bung and play Metallica, on repeat at max volume until the Sugden runs in or your neighbours complain.
Class A amp-best way to burn-in?
Hi-got my new amp today-a class A Sugdena21-any tips for the best way to run it in? I had my dealers on loan about a month ago-his was well-run in--noticed tonight it lacked a bit of weight and sounded ocassionally a little compressed to how I remembered it..this did change after about 4 hours becoming less noticeable.....will simply leaving the amp on all the time do the job? It's hot but it's on a rack thats well aired... Thanks in advance, Ben
