I bought a couple DIY preamp kits from a seller on eBay. When I received the kits, one was designed to use 4 single diodes and the other uses an inline bridge rectifier; but they didn’t send the bridge rectifier. I emailed them and they sent an electrical schematic that doesn’t even show that part of the circuit. How do I determine what I need? The diodes that they sent are HER607.
The first image is a picture of the completed board with the single diodes:
The second picture is the inline bridge rectifier design:
Here’s a snapshot of the data sheet for for the HER607s:
Any help would be greatly appreciated!
