Welcome to the Phorum 
There is plenty of help available right here.
The first thing to try would be, touch the center terminal of the volume control. You should hear a 60 cycle hum. If you hear a hum, that tells us the 6F6 and the 6Q7 tubes are working. It also tells us the complete power supply is working. If you do not hear the hum, take voltage readings on all the pins on the 6F6 and the 6Q7 and get back to us.
