/diy/ - Do It Yourself

Hello /diy/ers.

I have an amplifier that i found and it's in pretty good condition. I changed some elements and made it work (sound-wise). The problem is that lights are not working. Voltage across the board for lights gives 0 volts. Maybe it transformer fault or maybe something on the board isn't right. Can you suggest me how can i check if it's the transformer or something else.

ALSO, I would like to ask if there is some way i can make lighting out of LED, using a second power source (12 volt converter or something else) and connecting LED, resistors to the button to get same effect like those lamps had

Thank you
