Thank you for viewing! This is an introduction to a power pack specifically for Marklin's Mini-Club (Z gauge). Before listing, I tested the output with a digital multimeter to ensure it met the specified values, and confirmed it is fully functional. I have also conducted running tests with actual trains. The forward/reverse switch also functions without any issues. There is almost no sticky dirt on the power cord, which is common with this type of power pack, and I believe the condition is good. The unit itself is also in good condition for its age, but there may be some age-related changes or scratches as it is an old item. Please check the photos carefully to assess the external condition. The connection points and the outlet have been cleaned with anhydrous ethanol, a cleaning agent for electrical components. The main specifications are as follows: ① Rated Voltage: 120V ② Rated Output Voltage: DC ~12V ③ Rated Frequency: 60Hz There is no outer box, so I will carefully package it and ship it anonymously via Rakuraku Mercari or Yu-Yu Mercari. Please understand that this is a used item and is sold as-is, with no returns or exchanges. *If you have any questions or would like additional photos, please feel free to comment.* MARLIN Marklin Rokuhan Transformer
