Hello Steven,
absolutely no hum - i am scared, too....   :topjob:
You have successfully completed the final stage of AMP building.
Now you have the golden master hands and the price of your AMPs doubles up! 
Cheers
Jürgen

Now I can cover everything in black goop!

Hey Steven,

it is a sign - keep the amp. Don´t sell your soul to the devil. You did that already - keep the amp anyway.

Keep rocking,
Robin
