Re: Transistor Help
Try 2SC458.
From memory it's a general purpose NPN silicon transistor used in a lot of Japanese kit. https://datasheetspdf.com/pdf-file/2...uctor/2SC458/1 Any of the jellybean types should sub for it - BC548, 2N3904 etc. - but you will need to allow for the different leadouts. |

Re: Transistor Help
That's probably a 2SC458, a very common transistor back in the day, various refs for substitutes on Google.
EDIT: Post crossed. Lawrence. |

Re: Transistor Help
I've used the BC549 as a replacement in an Akai tape deck observing the different pin layout. The original 2SC458s have a habit of going noisy.
