Somewhat Relevant Photos

Opened the Delhi made amp for minor service
The orange cap near the Ic was changed from 220 to 100 micro farads, and the matching one for the other channel too changed to Keltron.
Contact cleaner sprayed in pots and switches.
Much improved sound.
Cost me 650 Rupees, you can see it is quite a messy build.
It has that FM/USB/SD Card/Bluetooth module, a switch to change to mic/line in, and can run on 12 volts DC too.
2 chip amps, 4440 made in China.
 
Photos had to be resized
