Amps are sweeties, try to keep them, Use one and keep the other for backup. I use to know Dennis Hadd. He's a good guy. I still have and use his Rocket 88.
You need to determine listeing style. If you like it loud and have a big room, then you need 90db plus speakers. If you like it soft and have a small room, then you don't need much power.
And have those tubes checked, especially the big 300s, some last and some don't, thats the way tubes are.
