Hello everyone,
I have very basic knowledge about electronics. This is my fun, getting hands dirty, Kill time during lockdown DIY. This is cheap money saving build (Cost me approx $ 90 Total). Sound is good and I enjoyed building it. Do suggest if any gross mistakes.
Sharing some pictures and details...
(1) Power on light and wire routing aluminum clips. (2) Extension shaft from robotics project. Brass piece was cut in half for two ends. (3) Main wire Terminal to distribute wires for fuses and transformer from AC mains. There is plastic film below PS boards. (4) 1.5A fuse for each channel. (Dont know if 1.5A is OK) Earlier I had two pole on/off switch but it broke so am temporarily using single pole switch (on live wire). Separate fuse on two PS board. There is also an extra third main fuse where mains wire comes in to the chassis.
(5) Capacitor from Input ground to chassis to attenuate RF (6) Grommet from CD player mechanism. mains in has turntable grommet. Yes this is cheap build (7) power supply 0v two wires and mains earth wire grounded to Amplifier main chassis (8) Four 4700uf Caps. per channel. Silly me as space was congested I thought caps would get hot so removed original sleeves then put on new one realizing the outer capacitor case will be carrying voltages.
(Top Left) Power on light plastic made from LED TV backlight bulb. (Top Right) 10 K volume pot made fake logarithmic with a resistor. (Bottom Left) Speaker Terminal. (Bottom Right) Aluminum piece is just for countersunk hole for screw.
Thanks for watching.
Regards.
