Thank you for viewing. This is the genuine Roland BOSS AC adapter "PSA-100P." This is a transformer-type adapter, the previous generation to the current compact models (such as the PSA-100S). Although it is heavier, many people prefer this model for its noise characteristics. It can be used with many BOSS effects pedals, as well as general pedals with a center-negative 9V specification. 【Specifications】 • Manufacturer: Roland Corporation (BOSS) • Model: PSA-100P • INPUT: AC 100V 50/60 Hz 8 VA • OUTPUT: DC 9V 200mA • Polarity: Center Negative 【Condition】 • Since I don't have any equipment to check at the moment, I have checked the power and voltage with a tester. • The cable warning tag is still attached, and it is in relatively good condition for its age. • Please check the details in the images. ※ Please understand that this is a used electronic device before purchasing. #BOSS #Boss #ACAdapter #EffectPedal #PSA100P #Roland #EffectPedalBoard Manufacturer...BOSS
