It is not the noise level of the machine itself. Please pay attention to this point.

The simple and sound circuit designed by dzdn29, 6H8C push EL34, adopt dual 290V tube rectifier, CLC inductance filter, the default super linear connection of the whole machine is about 10W, the triode connection is about 8W, it can be used to push 100W and the sensitivity is above 88DB bookshelf speakers or floor speakers. Users who listen to vocal strings can buy this power amplifier. Users who like to DJ or turn up a loud volume are not recommended to buy it.
