I'm going beyond mere service and inside-gear pictures here - this section is about projects such as modifications, racking, or stuff of an overall bigger magnitude.

Working on electronic devices such as described on this site can involve LETHAL VOLTAGES - especially in tube amplifiers, you're dealing with up to 500 Volts. If you're not absolutely sure about what you're doing, better have a qualified tech do it for you - otherwise, there's a chance you might hurt or even kill yourself. Really.
