Yep, sounds like a dead short if that's all that's happening. The tubes' filaments probably wouldn't be visible 'til around 70 volts. Did you bring it up to full power? Excuse the question, but the incandescent bulb is wired in series with the AC output socket, right? (The duplex receptacle has me guessing).
