Maude Posted May 28, 2015 Share Posted May 28, 2015 Morning folks. Does anyone know a good amp tech in the Plymouth/Saltash/Liskeard area? I have an Ashdown bass head that keeps popping the little glass fuse. Many thanks. Quote Link to comment Share on other sites More sharing options...

Maude Posted May 28, 2015 Author Share Posted May 28, 2015 Good old Basschat comes up trumps again. Less than twenty minutes and I'm sorted. Quote Link to comment Share on other sites More sharing options...
amillar Posted July 25, 2015 Share Posted July 25, 2015 (edited) 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!
