How Do I Know If My Rectifier Tube Is Bad at Shannon Mcelroy blog

How Do I Know If My Rectifier Tube Is Bad. For example, an emission test is analogous to checking the filament on a lightbulb. To diagnose which tube is bad, if you have a two channel amp, the most important thing is to determine, if possible, whether the problem is on both channels or just one. Your amplifier's preamp and power tubes require a dc voltage to operate. Sadly nearly every owner of a valve amp has no awareness or skills or equipment to check whether their rectifier valve (or for that. If the tube isn't lighting, and doesn't. If no audio signal passes through it, how does it affect an amplifier's sound? The rectifier tube provides the high b+ dc voltage and when the tube goes bad you get no sound. You can't damage the amp by subbing preamp tubes (as. The amplifier's power transformer converts the incoming ac line voltage to the levels required. First, keep in mind that a tube rectifier is not an audio amplifying device. If the filament is intact you get a “good” reading and if the filament is blown you get a “bad” reading. Try a known good 12ax7 in the 3 preamp tube positions, one by one. Usually when the rectifier tube goes bad it will blow a fuse or exhibit low voltage output depending on how it fails. If you can tell that it is in both channels (even if only slightly on one channel), it is most likely v1, which is common to both channels.
