Difference between mesa boogie tubes replacement
Current and voltage are two totally separate electrical parameters, though when you multiply them together, you get power which is measured in watts. When you set the bias of an amplifier, you are adjusting the static voltage at the control grid of the tube in order to produce a desired amount of idle current flowing to the tube's plate.
A small change in grid voltage, produces a large change in the amount of current flowing. That's basically how a tube works and the essence of amplification: a small change causing a large change. Here, it's a small voltage change causing a large current change.
The bias conditions are what determines how much current flows through the power tubes when you're not playing. What drives your speakers is fluctuations in that current flow when you are playing. If the amount of current increases and decreases times per second, then you'll hear an A note. If the fluctuations in current flow are large and still at per second, you'll hear an A that is loud!
For purposes of biasing, it's the amount of "plate current" flowing with no signal applied that's important. Unfortunately, current is hard to measure because the circuit must be interrupted as in "cut the wire" and the meter spliced "in series" with the broken circuit. But measuring voltage is easy. It is not necessary to interrupt the circuit because a voltage reading can be taken in parallel with the circuit intact. Thus, as a matter of convenience, most bias settings are given in volts at the grid, even though current through the plate is the important factor.
As long as the tubes are "in spec", the right bias voltage will always give the correct plate current, so there's no need for the bias voltage to be adjustable! Merely plug a matched set of MESA tubes into one of our amps and you're ready for tone. We always have a great selection and are happy to assist you with getting the right tubes for your amp! It has been edited for this post. Share this article. Many other amplifiers use adjustable bias or balance controls to compensate for over- and under scale tubes or to help equalize the difference between mismatched tubes.
Just as important as proper matching are the other tests we conduct on each power tube before it gets the MESA logo: Heater current both surge and stable , Warm up time, Plate Current at idle, with signal, and AFTER being driven into massive clip, Screen current, Grid current actually predicts tube life and short-circuits… then the computer switches off and a technician listens to each tube for noise, banging it repeatedly with a wooden hammer to test for microphonics and reliability under shock and vibration.
Best tubes, best warranty and the best customer service. Why not? This probably arises from the Groove Tubes long-standing promotion that their numbered categories WILL affect power and tone. The approach for the GT range is that weak tubes the lower number categories WILL reduce power and soften the sound, while the highest numbers do just the opposite, giving cleaner, louder, harder response.
We reject both extremes. In contrast, we pioneered and patented multiple wattage and power configurations that are channel-selectable within the amplifier and provide different levels of power along with different sonic characteristics, all carefully designed and consistent. You can choose among single-ended Class A for a sweet low power purr-- up to full-bore Class AB multi-tube lash-ups for maximum damage-inducing output.

| Hotel bettingen am mainstay | We make it easy. Such strict selection and close tolerance allows us to permanently set the bias in each amplifier so it never needs re-adjustment. Many players may accept the quick and simple answer when asking about using Boogie tubes in their amps. A small change in grid voltage, produces a large change in the amount of current flowing. You're after the most highly-regarded blues, rock and metal amps in the world. Combo models are equipped with sweet sounding Celestion C90 speakers, which are designed specifically for open back cabs, releasing a robust low end and excellent dynamic response. |

Most all of us want high performance and low prices. Many other distributors are interested in selling unloading their entire inventory of tubes. Many other amplifiers use adjustable bias or balance controls to compensate for over- and under scale tubes or to help equalize the difference between mismatched tubes. Cheers and Thanks! But if, hypothetically, I wanted to buy tubes from a company other than Mesa, should I specify anything besides the tube types, or adjust anything on the amp? Yeah so what - every reputable tube seller does that. |
