Thanks guys for getting me straight on the setup of the tubes. I got them in last night. When I first played the Cortese last night I was kind of unimpressed. It sounded hard and brittle with no bass. I let it play overnight and it did seem to sound better this morning. My nephew came over today to hear it. He is a guitar player, and he was playing with the gain switches. I had the 2 toggle gain switches on the top a low gain. When I would adjust the gain knob in the back it seemed to make no difference in the sound. When we moved the top gains to high, and adjusted the gain knob on the back I could hear the differences. All of a sudden there was tons of body and slam to the music. It took on a whole new life. Now I can't turn it off! I am getting a slight ground loop hum on phono. I have a ground wire from the ground post on the pre to the ground post on the back of the tonearm plug. Any ideas? If I take the ground wire off I still have the same slight hum. It is not bad and cannot be heard if music is playing. I know this thing will continue to get much better over time. It is going to be a fun trip!
