Glowing vacuum tubes in a 1960's Fender Bandmaster Reverb guitar tube amplifier.

Summary

[edit]
Description
English: This is a Fender Bandmaster Reverb guitar tube amplifier chassis. The three large tubes on the right are two 6N3C power tubes and a GZ34 rectifier tube at far right. The smaller tubes on the left are 12AX7 and 12AT7 preamp tubes. The blue glow in the power tubes is caused by electrons colliding with gas molecules. The faint red glow in the power tubes is "red plating" caused by excessive electron flow hitting the tube plates (anodes).
