Jim, did you manage to pinpoint the problem with the assembler? Out of spec part(s)? Bad assembly practices?
I really am curious.
Thanks,

That makes a lot of sense from the behavior.
Good job sussing it out and getting it fixed. It happens.
As an old QA guy, there is no test bed like the real thing.
I'll be buying another one now that it's fixed, count on that.

Quoted from Rottendog:The pre-drive transistor was wrong value. It should be a 2N3906 (I think). I will pick up the exact transistor number at the shop tomorrow and post again.
My build house asked me if they could substitute and I said yes...... It was my fault not anyone else's!
Look for tomorrow's post to know the exact part. We will fix for free though if you send us the board.

Quoted from Rav:Look forward to the post - I've got this issue too but being based in the UK seems a right pain to post it back overseas
Get the exact specs for the type and location of the incorrect transistors - they should be cheap and easy to replace for anyone with basic electronic repair skills.
