hifi engine


I am 40 years out of date, working with electronics.
and have just started back with a small project to repair a goodmans 150 amp from 1977

I have found a circuit diagram, but have run into a small problem a lot of the blown transistors are no longer around.
Is there a good transistor aquivalant guide for downloading.

I have no stock of any items required so i am trying to order from one place to avoid excess delivery cost.
any advise welcome.

Re: re-leaning

I think NTE has their replacement guide on-line. What transistors are you looking for?
