Receiver or Preamp with 5 channel analog outputs

Hi, I have a Butler 5 channel tube amp with analog inputs for each channel. I want to hook it up to a receiver or preamp that has 5 channel home theatre outputs. The problem is I can't seem to find an el cheapo receiver for my needs. I've looked at Sony, Denon, Yamaha and none seem to have 5 channel analog outputs for an external amp. The all do digital. Can someone advise what receiver or preamp would work for me, but at a reasonable price?
