Watt Puppy 7 needs new or used Amp and Pre-amp


I'm building my system on a pair of Watt Puppy 7 speakers. Currently I have my vintage Marantz 250 amp with an SAE Mark 1B Pre-amp/equalizer.
I think the preamp needs to be replaced first. I need some advice on putting together a system on a tight budget. Thanks for helpful advice!

FWIW, the Watt/Puppy system is designed for tubes. They are easy to drive- our local dealer demoed them with our 60 watt for years. Wilson's national sales manager has used tubes for at least the last ten years...
Tube pre - ARC LS5 MK II or III or LS26 - Amp - NuForce 9SE V2 or Classe CA-2100
Mcintosh pre amps, arround 3000 (C46 or C2200) are also good choices to W/p 7. I run my w/p 7 frist from MA2275, then bought a C200/MC 501 combination. The combintion is just great!!
