Default Fixing SMPS on car amp - Transistors

Hi guys

Fixing an old kicker amp with a failed smps. Just no voltage anywhere on the signal side. Uses a 555 for the source, which drives a couple of gain stages before hitting the main Tranisitors.

Being old, an being that I'm in NZ and limited for suppliers , i cant easily get replacement transistors.

I was gonna try substituting 2sc945 with bc547's, and the 2sc2316's with bd139's.


Any ideas on this??
should work right? (figers crossed)

Cheers
Dave
