This is a power supply for Counterpoint SA-5 series preamplifier. The power supply working very well, all parts of it are original and it is in excellent condition. The rectifier tube is EZ-81 made by National. Cosmetically the item is in great shape with all the writings are in tact and clear, there no scratches or mark in anywhere. This power supply can be switched to work on 230V ac also, currently it is set up for 120V ac. Continental USA shipping is $18.00. I am sorry for the reflection of the light on the photos.
