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."

Not just a 2 faced, but an 8 faced bitch who acts and dresses like an absolute slag. She can’t keep a boyfriend for very long as she likes to flirt with any and every guy in a five mile radius. They are a type of slag who enjoys the chase but not the relationship and can’t keep their grubby little hands to themselves. She is the biggest backstabber you will ever meet and can’t keep a secret for very long. You can not trust this class of slag with any information because it will get around faster than they catch STIs.
The girl over there, she is a proper class B slag

a class B pooper poops very loudly at school if your in the bathroom with a class B pooper you will know. with a combinations of loud farts and just very loud pooping habits you can on bad days hear them from outside the bathroom, if you are a class B pooper you are usually annoying to most but have a close circle of friends. class B pooper has very loud farts in and out of the bathroom that they will let slip during the day. when the are hazed they are usually recorded while pooping but dont notice very often
