I've been thinking of sending my amp off for a service, it sounds fine in operation and is perfectly quiet, there is a slight channel imbalance favouring the left channel but that is sorted with the balance control.
The issue that concerns me is the quite large amount of noise on first start up, regardless of volume knob position, there's quite a bit of crackling and popping for the first 10-15 seconds until what seems like something is settling, then it's perfectly quite throughout, the longer it's been switched off the worse it is.
Not being electronically minded (with amps at least, I mainly deal with large 3 phase appliances at work) I've no desire to look at it myself, I'll probably end up sending it to Sugden but I hope it's nothing detrimental to it's sound.
