Stabilized Power Supply, Daiichi Kosho GSS500, Low Usage Frequency
This is a one-owner item. It is in good working condition. I used it for about 2 years mainly for listening with an IC-705, and occasionally for FT8 transmissions. The outer box has some tears.
Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.
Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.
