Bad Cat is a brand of music equipment. Their tube amplifiers are for Guitars, and can be highly customized. They also carry with them a lifetime warranty.
A: TUBE AMPLIFIERS are operating at higher voltage which makes the dynamics of amplitudes more desirable. Other then that there is no other reason. tube amplifiers are bulky heat generating components efficiency poor and frequency limited.

Yes, they absolutely can and do sound different. An amplifiers sound is colors by the materials used to build it. Is it tube? Solid State? What kind of electronics are in it? Etc. Etc.
There are two names for the tube used in Class A amplifiers developed in the USA. This valve in the US is called vacuum tube audio amplifier. In the UK they are known as valve audio amplifiers.
The Engly company, a German company located in Germany, manufactures high-end tube amplifiers for electric guitars, with a main focus on creating good quality metal amplifiers.
I checked the spec sheet for this tube, and it's good for two basic circuits: low-level amplifiers and oscillators. So yes, it would be fine as a preamp tube or an input tube.
Years ago all we had was tube amplifiers. As long as its a bass amp (so you don't blow out the speakers) there is no problem.
From Wikipedia on the subject of Tube Amplifiers...."Tube instrument amplifiers are often equipped with lower-grade transformers and simpler power regulation circuits than those of hi-fi amplifiers. They are usually not only for cost-saving reasons, but also are considered as a factor in sound creation. For example, a simple power regulation circuit's output tends to sag when there is a heavy load (that is, high output power) and vacuum tubes usually lose gain factors with lower power voltages. This results in a somewhat compressed sound which could be criticized as a "poor dynamic range" in case of hi-fi amplifiers, but could be desirable as "long sustain" of sounds on a guitar amplifier. Some tube guitar amplifiers use a rectifier tube instead of solid-state diodes specifically for this reason."
Tube amplifiers can be purchased from several places. They can be purchased from a music store in one's area. They can also be purchased from online retailers such as eBay or Amazon.

go on you tube
One of two things. A reflected image causing `ghosting' in the signal, or your convergence amplifiers have gone bad. (If it's an older three-tube projection set, that's quite common.)
