Swan 117XC Power Supply: Update 7/29/25: PS #1 has been sold. PS #2 Remains Available
For Sale are two Swan 117XC power supplies:
1. The PS on the left was rebuilt by AD4DQ (‘Brutus’ on the Swan Facebook Group). He replaced capacitors, out of tolerance resistors, and diodes. The PS is fully functional. Included with the PS is one of the custom dust covers shown in the photo.
2. The PS on the right is also functional. I opened it for inspection and found that not all the capacitors were replaced by the previous owner. I purchased a Harbach rebuild kit (over $100) for the PS but did not get around to installing it. Included with this PS is the rebuild kit and one of the custom dust covers shown in the photo.
The price for PS is $200 plus $20 towards shipping. Local pickup on the North Shore of Massachusetts is also available.
