LM380N based Stereo Summing/Mono Amp
This is a nice variantion on the LM380N based amp used in most
of the projects on this site
It accepts either a stereo or mono input
Designed by D-Zine

Parts List:
1x LM380N 14-Pin DIL Audio Amp
2x MKS2 0.1uF 63vdc Capacitors
1x 470uF 16v Radial Electrolytic Capacitor
1x 10K Miniature Horizontal Carbon Trimmer
1x 2R7 1/4 Watt Resistor
2x 10K 1/4 Watt Resistors
Matrix Board (14 copper strips x 13 holes)
Tinned Copper Wire (Links)
26 Tracks to cut
7 link wires
Video Amplifier
One of the problems of connecting consoles or PCs to arcade monitor
is that their P2P output
is usually less than that of real arcade boards.
This can be corrected by adjusting the monitor and optionally
putting some electrolytics in the
video signal path to reduce the DC offset of the signal
This circuit is a nice/cheap video amplifier, which brings the
console/PC's video output closer to that
of a real arcade board
