In this video, he also demonstrates the ease of changing out tubes. The various types of rectifiers include a half-wave rectifier, full-wave based on center tapped and bridge concept. This 274B tube's filament draws 2.5A of current. By having this information on a chart you can choose a rectifier tube that will best suit your playing style. So you need a 5U4 or 5R4, as @Steppin' Wolfe 's chart shows. At first, from my reading (and the only difference I could see from the two AA1164 schematics, one w/5AR4/22Kbias; one w/5U4G/27Kbias), I decided if the bias resistor was 22K the correct rectifier was 5AR4, like my Princeton non-reverb, with tube chart; 27K would denote a 5U4G was needed. The MESA® 5U4G Rectifier Tube is a classic 1930s "Coke Bottle" design. Providing a deep and rich tone, a best fender tube amp features a superior clean sound and real depth when you compare it to a solid-state amp. For more gain, you can replace 12AU7 with a 12AV7. The chart is most useful when you use it as a guide to the relative voltage drops of different rectifiers. This tube has been a favorite of many professional . Both sound great, and both last a long time. Here are some rectifier types. Finding a preamp using one rectifier tube is sweet. As it can keep up with the fluctuating current. A diode is a two terminal semiconductor device which allows the current to flow when it is forward biased and blocks the current when it is reverse biased. When the plate voltage is lower to the output tubes the output tubes will become more biased so they may sound harsher. If you want gain, go for a Sovtek 12AX7LPS or a Mullard 12AX7. 5AR4 rectifier (17v drop), Mullard especially, has one of the smallest drops in voltage, which lead to tighter sound, but also more transparency and more speed, but warmth was sacrificed - with type 45 and 2A3 tubes that was not a desired effect.
