    Glad to hear that.

    LC parallel tank circuit

    The schematic shows 0 volts on the emitter of the npn transistor. I would think that the emitter to be ground. Inject the signal between the base of the pnp transistor and ground The output from the collector of the npn transistor will be higher at resonance and drop off as the frequency is...

    Class A amp with NPN BC547 transistor

    Most of your input signal will go to the emitter and very little on the collector. Try putting a 22uf capacitor in parallel with the emitter resistor.

    Small Project Advice

    That is a good idea. I made a valentine for my wife out of construction paper and I wrote on the front for her to be My valentine with an exclamation point. I made a small hole to mount an LED in the hole. I then wrote I LOVE YOU with another exclamation point with an LED like the other one. I...

    Experiment with NPN transistor BC547

    You may instead do away with the pot and use a 10k resistor from collector to the switch and from the switch to the base. That should work as well.

    Farewell

    Sorry to see you go. You will be missed.

    Capacitor Swap

    Yes, but make sure that you connect + lead to the emitter and the - lead to ground.

    SMPS

    check your diodes if it has any. It is hard to troubleshoot without a schematic.

    Phase Shift Oscillator Puzzle

    You said you used a lower pass network and it worked. Try using a higher frequency transistor.
