[cctalk] WTB: PSU for DEC PDP8F

Hi there, I need a power supply for my PDP8F computer. It is missing. The PDP8F 19" chassis box came in 3 different depths, 600 mm (PSU front to back) 370 mm (PSU across the back) 300 mm (PSU front to back) I need the shallow one, the 300 mm PSU front to back. Do you have one available, or know where I can get one please. Even if it is dead! regards ray
