Class of 2028 

2009 and 2010 borns aka the ones that were non-existence and only came when we said goodbye to the 2000s and entered the 2010s , They play games like Minecraft and Roblox and even Fortnite, They are loud and obnoxious to deal with due to their feeling that they are cooler. Even tho they look up and get almost everything and are secretly learning the most or even all things from the 2000s decade borns and that isn't a good sign of the future. If you have one of those little children, then best thing to do is use parental controls like ffs they will find a way to access stuff that they aren't supposed to see nor use! They are easily be fooled and played around with like a toy. Have inner lower self-worth and self-esteem due to all this depressing shit that is being throwed around

Person: "When are you going to College?"
Class of 2028 Kid: "Uhh….I don't know?" *shrugs*

Class A/B

Electrical term, Class A/B Amplifier.

A class A/B amplifier is also called a psh/pull amp. Class A/B amplifiers have 2 amps, one to push the speaker out (+), the other to pull it in (-). In guitar amps that use tubes, this means that one tube, a driver tube inverts the signal polarity before it reaches the B side.

A class A amp pushes and pulls the speaker, and thus must do more work. Most commercial (in home) amps (stereo receivers, etc.) are class A amps. Class A/B is generally used in guitar amps over 30 watts, high powered Bass amps, and professional power amps. Class A/B generally delivers the same power at double the impedance. So if an amp gets 100w per side @ 4 ohms, then it will generally get 200w bridged mono @ 8 ohms. This is rarely 100% true in practice.

Class A/B is also called "Bridging" an amp (transistor amps generally).

"Fender Twins use 4 6L6s in a Class A/B circut to deliver 85 w RMS @ 4 ohms... In other words, they's pretty damn clean boss."
