Look at the color bands on the resistor, that can be entered online to tell you what it is. New boards are about 15 bucks if you can’t find resistors locally.

Sorry I was incorrect on the price...bad memory :-(
Anyways R3 appears to be 0.5 ohm, R1 I can't tell if the first band is orange or brown, it's either a 0.1 or 0.3 ohm resistor.
Both are +/- 5% tolerance carbon resistors, not metal film (blue colored).

The diode is a 1N400x.

No the resistance value is way too high. Those are a 100x more resistance than what's on the board.
You'll need to get the correct values or spring for a new board.
