What? the ha ho!
Im building the exciter boards for the 3 coil experiment and I have run into something strange , bad, but worked out. The TIP31A's that I just got in from Mouser are blowing seconds after powering up at 24V. I can put the original one Ive been using on the setup and it works fine. ST the manufacturer must have changed something. They spec out the same but something is clearly different. My solution is to use the TIP31C, it works fine. Has anyone ever run into variables with same spec components? I'm taken aback by this, I blew through 8 TIP31A's.
