FS300R12KE3, AGDR-76C, used(second-hand items), two sets available, never repaired, a bit dirty when disassembled. The boards and modules were disassembled and cleaned. The modules have been tested and are guaranteed to work; the boards’ condition is unknown. The boards should also be good, but there are no conditions to test them. Modules are 500 per set, guaranteed to work; boards are 200 each, no quality guarantee. Welcome to purchase both sets together. If interested, feel free to contact!
