Thanks Paul, I know what you mean about the switch on moment it really is quite a nerve racking moment.
On one of my first amplifier builds years ago I got the magic blue smoke from one of the output transistors and it was a massive anti climax. I just switched it off and walked away, I remember thinking WTF do I do now ?.
Anyway I got some good advice from PFM about testing the circuit and I managed to fix the problem which was a mistake by me on the build so it was happy days in the end.
Amp No2 drilling of case ongoing, watch this space
