Could anybody help me to find a specific transistor for a preamplifier for Piezo pickups? The preamp works with the 3.
In the attachment I prepared a schematic of the preamp. Please help me to understand what vatasheet is used here. You forgot to tell us what the pickup is used for. The horrible circuit will work with an N-channel Jfet or NPN transistor if the piezo pickup is in a drum.
The circuit will not be a linear amplifier with a high input impedance if a Jfet is used. The circuit is designed to use an NPN transistor but will work poorly when a piezo pickup or magnetic guitar is used because its input impedance is too low. If an N-channel Jfet is used then its gate must have a 2. Use a 2N or 2N The pickup is a simple piezo-disc buzzer used in a very cheap throat microphone.
Now it works just lovely! The “horrible circuit” works actually very well. Do you think this transistor is possible? I just copied it from the PCB that was in the throat-mic housing.

It is a single layer PCB and simple enough not to make any error. The circuit you found will not work with a Jfet but will work with an NPN transistor and a low impedance signal source not a piezo.
A piezo throat mic is a contact mic. There is a similar circuit at http: Could they work with 3. Since the preamps in the PCs do always have a decoupling cap, ring and tip can safely be shorted to supply the 3. It has a low input impedance which loads down the signal level from the high output impedance of a piezo mic and the transistor has low voltage gain so if you speak loudly you will make an output.

Posted August catasheet, The sound card needs to form part of the circuit.
