What Goes Up Must Come Down V1

My second little 'tube amp', this time with onboard tremolo! Now it's not great but it gets the job done... I suppose. Tube really needs to be a 12au7, and the IC needs to be the LM386N-3. The LM386N-1 will work but it has a slightly lower output capability. Speaker is 8ohms. These little amp ICs are really good at small speakers but if you want something a tad more useable I suggest building version 2 of this design.
