Why not go for an SVT IIP preamp or the SVP Pro and a light weight power amp the Sumo is tiny and kicks out 600 watts.
the Ampeg preamps can still be picked up at reasonable prices.
I have an SVP Pro and an SVT-IIP I prefer the IIP for a creamier warm tube sound and the Pro for the growl but both punch you in the face when you let rip.
