are valve amps and tube amps the same?
603568
If you hear somebody talk about valve amps, they're the same as tube amps. “Valve” is an English term, while “Tube” is an American term. They both refer to the vacuum tubes/valves in the amp. Compared to the other types of guitar amps covered later, tube amps use ancient technology.

Amperage. Voltage and amperage are two measures of electrical current or flow of electrons. Voltage is a measure of the pressure that allows electrons to flow, while amperage is a measure of the volume of electrons.

The ECC83 Valve – also known as the 12AX7. The 12AX7 Valve (or 12AX7 vacuum Tube) is a small preamplifier valve which is identical to the ECC83 – same valve, just a different name. It has two identical triodes both of which have a high voltage gain. It is used in 99% of all guitar amplifiers.

So amps measures or indicates the maximum time a tool can continuously run without exceeding the temperature limits. Amps basically measure how effectively the motor cools itself, not how much power it has. With this in mind, more amps can be good because motors will run longer and won't heat up as fast.

VA: What's the Difference Anyway? Watts is the real power drawn by the equipment, while volt-amps are called the “apparent power” and are the product of the voltage applied to the equipment times the current drawn by the equipment. ...

Op amps have two inputs and one output. Instrumentation amps usually have three inputs (ref is an input) and a gain control facility, and one output. Differential amps usually have two outputs and usually two inputs. None are directly electrically interchangeable and this is a performance and usually functional thing.

Look at the stem where it comes through the rim. If it looks like the one in Strech's link, that's a tubeless valve stem. If it is a bit longer, and has a nut on the outside, it's a tube. Inner tubes have a nut on the valve stem to keep it from being pulled into the rim.

The crucial difference between voltage amplifier and power amplifier is that a voltage amplifier increases the voltage level of the applied input signal. As against, a power amplifier is the one that boosts the power level of the input signal.

Amps would be the volume of water flowing through the pipe. The water pressure would be the voltage. Watts would be the power (volts x amps) the water could provide (think back to the old days when water was used to power mills). ... The electric current is measured in amps.

5-Channel or more Amps. 5-Channel amplifiers are designed for complete system amplification. These amps have 4 channels dedicated for speakers and a single channel dedicated to a subwoofer. These five channel amplifiers make amplifying an entire vehicle easy and with the installation of only a single amplifier.

Voltage is measured in volts, current is measured in amps and resistance is measured in ohms. ... The voltage is equivalent to the water pressure, the current is equivalent to the flow rate, and the resistance is like the pipe size.

Amps are simply the amount of electricity used by the item. Volts are the measure of the force of the electric. Amps multiplied by volts gives you the total wattage (workload). Understanding how the three terms relate helps with understanding the electrical requirements of an item.

All 5-watt tube amps will be louder than others, some candidates maybe loud enough for a potentially gigging and rehearsing without any additional cabinets. However, If you own a low wattage amp you like the sound of but want to squeeze more volume out of it.

Fundemantally one kVA is equal to 1,000 volt amps. Whereas a volt is for mesurement of electrical pressure an amp is a way of electrical current mesurement.

Ampeg is THE standard for rock and roll. Admittedly, that is mostly the VHT, but all of there amps are very good. ... If you're more into low mid thump, no highs Ampeg would be the way to go.
