Why did you install a new 1N4007?
We told you that it is not needed for the circuit to work.

Show us photos of both sides of the board.

The KIA6213S amplifier chip is a 9-pin SIP (single in-line plastic) chip.

pin-5 = GND
pin-7 = Vcc

Using a sharp X-Acto knife, cut the copper trace at pin-7 where it is indicated in red.
Turn on power and measure the voltage across the power input at the red and black wires.
