I made this video amplifier while attempting to add RCA audio/video jacks to a ColecoVision, and while not really knowing what I was doing. This is mostly here for posterity.
- circuit board of some sort (pictured: 1/2 of a radio shack "dual general-purpose ic pc board" cat. no. 276-159B)
- some wire (22 gauge stranded wire is recommended)
- LM318N (IC1)
- 2x 10k resistors (R1,R2)
- 2x 150 ohm resistors (R3,R4)
- 27pF capacitor (C1)
- >1uF capacitor (C2 - see schematic)
- 47uF capacitor (C3)
