This is an ETA PD8L power distributor. I have confirmed that all power is on and the left and right lights are illuminated. The original light cap came off, so I attached a different cap and wrapped it with tape. I don't think there will be any particular problems in use, but you may want to reinforce it if you are concerned. 【High-Quality Power Distribution】 The ETA SYSTEMS PD8L is the perfect power distribution unit for professional audio equipment.
