What does V1 tube do?
It is the first point in which the pure guitar signal is amplified and determines the way every other aspects of the amp will respond to the guitar signal. The guitar signal is immediately amplified by V1 then sent to the tone circuit and on to any other circuitry before hitting the power amp tubes.
Where is the phase inverter tube?
The phase inverter is the last stage in the amp before the output tubes, and in all amps other than single-ended types with just one output tube (Fender Champ and Vox AC4, for example), this stage splits the signal into two reverse-phase strands to send on to those big bottles for final amplification.
Is 5751 same as 12AX7?
Choosing pre-amp tubes by gain factor For example, the common 12AX7 tube has a gain factor of 100, while a 5751 tube (which is often used in place of a 12AX7) has a gain factor of 70. This means that if you plug a 5751 into a socket that expects a 12AX7, the pre-amp will have about 30% less gain.
Can I replace 12AX7 with 12AY7?
You can interchange a 12AX7 with 12AT7, 12AU7, 12AY7 or 5751 as they are all the same pin structure, however they will each give you a different result in your amp. Each of these tubes has a different gain factor, which means some will give higher gain and others lower gain.
How important is the phase inverter tube?
It makes sense that the phase inverter is very important. It’s feeding the signal from the pre-amp into the power-tubes and has to make that signal change very cleanly, without adding any distortion. At least that’s the idea for an amp running very cleanly.
Are all tubes made in Russia?
Russia is one of only three countries still making vacuum tubes for use in reproducing music, an aging technology that nonetheless “warms up” the sound of electronic music in audio equipment.
How do you balance a three phase system?
Three-phase load balancing occurs when the loads of power supplies, such as a three-phase rack PDU, are spread evenly across all three phases (L1/L2, L2/L3, and L3/L1). It can be achieved by having an equal number of devices plugged into PDU outlets for each phase and drawing an equal power load on each phase.
