one of them is the parts list for the circuit with the 2009 transistor which i wrote down on it as a germanium transistor

I looked at the spec sheet for the ST2009 dhi semiconductor, but i could not find anywhere it said that it was made from Germanium...
Silicon took over from Germanium in the 1960s, but there were semiconductors in the late 1990s which incorporated both Silicon and Germanium as Germanium was seen as more durable :)

2 ways to replace the transistor. one is to find its data sheet on google and from that you can find one with similar spcecs...most important is frequency response and power input/output. The other way is to simulate the circuit with a computer software then you can find a replacement by knowing to frequency it produces.
