lab series l5 build working
« on: February 23, 2021, 08:41:22 PM »
started out with the schematic and the board layout shown. copied the layout in adobie photoshop . sized it so the op amp sockets would fit. made it in 3 pieces, channel 1, channel 2, and so on. using pnp blue transfer sheets. copied the power supply same way. sounds awesome!!!!!. fan on power supply was hooked to raw full wave diodes positive side and ground  1k resistor on the ground wire of fan. this way you eliminate fan noise into the supply otherwize youll get fan noise. antec 22volt/ 22volt transformer.
will post pics.
