Step 7Bypassing C15
To gain the access to the medium power transistor's pre-amp we need to bypass the capacitor marked C15 on the PCB.
Place a piece of wire along the edge of C15 and use it to glob solder across the capacitor.
If the connection is correct you should see 10k ohms between the end of R10 closest to the drilled hole R and the base of the pre-amp transistor. You should also see 100k between the base and the emitter of the transistor (make sure to put the positive lead on the emitter).
