What sort of problem are you having that requires a diagram? ••• More options Share D dips1982 Member Joined 2012 2014-11-07 10:57 pm #3 2014-11-07 10:57 pm #3 Hi Perry, power supply section has gone. Just wanted to see what parts to order, resistors, diodes etc. I have the mosfets. Many thanks ••• More options Share P Perry Babin Member Joined 2003 bcae1.com 2014-11-07 11:05 pm #4 2014-11-07 11:05 pm #4 You'll have to remove the FETs and then test the drive circuit to see if there is further damage. The driver transistors commonly fail. Did anything fail in the output stage? ••• More options Share D dips1982 Member Joined 2012 2014-11-07 11:46 pm #5 2014-11-07 11:46 pm #5 I havent checked it fully yet. Will check and report back. ••• More options Share Show hidden low quality content Status This old topic is closed.
