'''Suitable modern replacement''' | |||
The 475 Service manual lists some of the transistors with alternatives, and some without - so I'd be careful to check that some need to be closer in spec than others. | The 475 Service manual lists some of the transistors with alternatives, and some without - so I'd be careful to check that some need to be closer in spec than others. | ||

In the [[Common Design Parts Catalogs|1982 Common Design Parts catalog]], -0367 is Cross referenced as AST3571 which appears to be a custom 2N3571. | |||
'''How to identify this transistor''' | |||
It's not very hard to identify these transistors. | It's not very hard to identify these transistors. | ||
They will have a 151-367 number on them and when tested will show a reverse polarity protection diode, which should not be there. | They will have a 151-367 number on them and when tested will show a reverse polarity protection diode, which should not be there. | ||
These typically have a 100% failure rate so you should replace them with the recommended transistor listed in the preview. | These typically have a 100% failure rate so you should replace them with the recommended transistor listed in the preview. | ||
