Night Shot – Amplifier
by Russ Knize on Mar.03, 2009, under
Night shot of the amplifer section. You can see the blue glow against the glass from stray electrons. This is very common with Sylvania tubes. Behind the blue glow, is the red glowing line from the electron beam hitting the plates (I can’t get the bias to go any lower with this amp). The two together look purple to the camera.
