Fired it up and...

Ok I fired up the amp last week and nothing! I've been trying to trouble shoot it for the past week. Here are a few of my mistakes that I have fixed but there is still no sound. I say no sound, there is a slight hum in the speaker, just no sound from the guitar.

I had the wrong input jack. I don't know how I missed this - The output jack I used only had two prongs and the correct jack is a switched jack with three prongs.

I found a wire that may have been shorting the circuit. It was the wire going from the volume pot to the tone pot. When the pots were screwed into the chassis the connections touched the brass grounding plate. I moved the wire around to the bottom side of the pots.

That's the latest update. I'll be out of town all next week and I think when I get back I'll have to take it to my local amp tech and see if he can help me.

I did buy the speaker today. I bought a 12" Eminence Wizard speaker from http://www.nationalspeaker.com/ as they are 6 miles from my house. After taxes the cost was $85
