The kit includes all electrolytic capacitors, rectifier diodes and resistors. NOTE: There are a couple variations in the Drake AC-3. Older version has a test point and 5 ohm resistor on C2. Due to how Drake used screws to mount the flanges of the twist tab capacitors, you will need to drill two holes to mount the Multi-Cap and Uni-Cap boards for C1, C2, C3 and C4.
