While I was on the forum I thought I'd just update this in case anyone else sees the same problem on an Ashdown Perfect 10: lower output transistor was completely short circuit, upper one was "leaky". I must admit the upper one fooled me for a while, but with help from Guy at Ashdown we got there in the end. Really I should know better by now and just change both straight away!

To set the bias, turn the pot fully anticlockwise, then adjust for 4mV across the two power resistors.

And a pleasure to meet another local bassist and top guy! :)

Cheers,

Andy
