Obviously this is not one of mine but one taken from a magazine from 1970. it uses germanium transistors however if you can't find them or they are too expensive just try some general purpose ones like 2N3906 instead of the ones listed.
There are a few odd values that aren't really readily available - just get the ones nearest to them - like in the case of the 50uf capacitor substitute it with a 47uf one and so on.
