According to a schematic I have (which is for a TS-808 clone, but it should be very similar), the input transistor has a 10K resistor and 1uF cap off the emitter. Going into the base is a 510K and 1K resistor. The collector goes to the +V rail. Have a look for those parts and you should be right.

I used 2N3904 transistors in mine, I don't get any noise issues with it.
