Plug a dual-triode vacuum tube (12A*7) into a breadboard. Or do it dead bug style with the screw terminals. Yay.

Add 0.5" hex standoffs to rear holes to support tube/board weight when plugged into breadboard.

I have used this board a bunch on a recent project, and it really beats solderin…

2 layer board of 0.97 x 0.75 inches (24.7 x 19.0 mm)
Uploaded: November 28th 2014

Total Price: $3.60

LM386N-3 chip audio amplifier PCB. I power this with 12V DC (Add a 100µF electrolytic filter/smoothing cap across the DC power input if using a wall wart). The other values are:

R1 10 Ω ½W metal film resistor
C1 0.1 µF 50V electrolytic capacitor (or a ceramic or film cap)
C2 0.047 µF…
