End of blog, I introduce our company ,wish you can get the original product of LD+. lol~.

In my audio shop www.fairsz.com there are many models of tube amplifier,  today I will introduce the electronic tubes used in these amp. Before 60S, the electronic tube use for almost all the audio appliances ,some for power amplifier, some for beautifying the sound effect. But time to 90S, the transistor took the place of it, since the transitor has the features of power saving ,small size, long life.With the progress of electroacoustic technology, people found that the electron tube had the advantage which the transistor did not have. People are beginning to pay more attention to the electronic tube. Now the electronic tube life of application is also improved a lot. The usual models of electronic tube are : KT88, 6J8P,6N9P,EL34-B,6P3P.... Here I introduce one kinds of tube amplifier, which use the KT88 tube. There are DIY kit for the fever fans to install themself. If you are interested in it, pls click here to know its details. http://www.fairsz.com/kt88-class-a-single-ended-tube-amplifier-kit-p-411

 

Famous China brands of tube amplifier are: Yaqin, Nobsound, LaoChen, Rivels.
