• WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.
    Building, troubleshooting and testing of these amplifiers should only be
    performed by someone who is thoroughly familiar with
    the safety precautions around high voltages.

No output and Loud squeals! Help!

A schematic would help here.
If the amp uses negative feedback, try hooking it up to the opposite end of the speaker winding (or if the speaker winding has a ground you will have to swap that too or reverse the connections of the primary winding - all of them if it uses screen taps)
