Tubes Asylum

Questions about tubes and gear that glows. FAQ

Just traded for an early verions aq-1003 - need to bias tubes but can't figure out where to put the multimeter leads - the black obviously goes to the speaker, but the red lead - don't know. There are 4 black holes on the side - presume for adjusting the bias. But how do I get a measurement? I'm sturmped and the manual that I have is incomplete.
