Responding to: ???'s previous message
TIP32 has typical hFE=10 only. It means that the base current of TIP32 must be at least 2,3/10=230mA

Dear Oleg, I hope you misstated "typical hFE=10" and ment "minimum hFE=10".

Designing by "typical" values is a BIG mistake always use the appropiate Max or Min..
