Recheck your circuit & component
Hi ERKAN,
I think you have fried the transistor. If you use 2N3055 transistor, do the following steps to check if the transistor still ok or not.
Other info :
Make the rotor rotate first then go for tuning.
Hi ERKAN,
I think you have fried the transistor. If you use 2N3055 transistor, do the following steps to check if the transistor still ok or not.
- Set multimeter in diode mode.
- Touch positive probe to transistor base and negative probe to transistor.
- You should see readings or beep sound from your multimeter.
- Now touch negative probe to transistor base and positive probe to transitor emitter.
- There shouldn't be any readings or beep sound from multimeter. If does then replace new transistor.
Other info :
- Bifilar wound 850 turns of #23 & #26 clockwise direction.
- Use battery 12VDC only.
- Positive #26 goes to 680 ohm then to transistor base and negative #26 goes to battery negative.
- Positive #23 goes to battery positive and negative #23 goes to transistor collector.
- Small push to rotor should rotate now.
Make the rotor rotate first then go for tuning.
