Power supply 220 v for Krell KRC-HR preamp

My father moved house 2 years ago but regrettably the power supply of his KRELL KRC-HR preamp went missing. Contacted Krell customer service but they say that Krell is unable to fabricate another PS to replace. I asked them for the elctrical plans so that I could source for someone to make a PS according to specs. Krell ignored my pleas! I would like to implore anyone who might be able to help. My Dad has KRELL monoblocks and it would be a shame if his KRELL preamp cannot be used! Please help if you can!
