This preamp can run it 150 tubes, you can also buy a separate power supply to power it, just plugs right into the rectifier socket on the preamp. This power supply can use big rectifier tubes like 874a Mercury rectifier tubes. I have one of his lower line preamps, which sounded great on it's own, but had a way better soundstage and instrument separation with the super rectifier power supply.
