As you sent me the photos, pls kindly check the PCB KITS of the EL80, and you can see that some of them have one black light and some of them have two black lights. Near the black light, there is a special series number of the PCB kits, kindly let me know the problem kits' number and then we could send you the spares accordingly!
for the PCB kits of EL108, kindly check the PCB kits are from one frame or different frames and which frame? Thanks a lot.
