Hello,

I need to make a simple FM transmitter.Please find the attached circuit. As I wasn't able to buy some of the parts, I have to use other parts instead. Can you please tell me if the following changes could work? If not, could you please give me some suggestions?
2p---10p
28p---27p
1n---1.5n
39K---33K
5.6K---5.1K
62p---56p
5p----10p

Thank you very much.

it is a vbery simple low quality circuit.
Its frequency will change when anything moves toward or away from its antenna and as the battery voltage runs down.
It will sound very muffled on an FM radio with no high audio frequencies.
You are changing the value of almost everything so it probably will not work anyway.
