Default Re: Philips N4450 Reel to Reel Tape Player

Sorry for all the questions - but If i want the machine to run properly and i want to try and fix it myself, where should I start?

I guess that replacing all the common fault transistors is a good place to start.

Replace all AC128s with BC327's
Replace all xxxx with BC 547's

Anything else?

My:
flip flops have BC147's.
tape tension is BC 147's.
auto rev is 157's and BC547
motor stop is BC557 BC547
