After having just built it I was away for the Bank Holiday (in the UK) and I just took it along to a place with no rack power. 50% chance it might have worked I even tried the USB port on the Owl board but I think that is for other things.
Fingers crossed it all fires up when I pop it in the rack then. I have checked all my soldering and passed the smoke test so hopefully everything will be ok.
The only concern is the closeness of the pads for R25,R26 and R29,R30 with the outer legs of Q1 and Q2. Without looking at the schematic I hope these are all at the same voltage as I may have bridged one R29 with Q2 outer leg!
Nice to have a forum with caring members so many thanks for responding. I am also building a TTSH via forum help on 'Mod' Wiggler and that is a good forum also.
