Early tube quality was more reliable and sound was more natural. The 4 ROEs are also in discontinued inventory, so it is inevitable that there are bumps on the surface. If you mind, don #39;t take pictures. The product will be deemed defective. Because the number of parts of the machine is limited and the output of the machine is limited, please consult before taking pictures. JHL 1969 amplifiers should not be unfamiliar to homeowners. The amplifier circuit is characterized by its bias in the Class A state, and the sound quality is partial to the timbre of the amplifier. Our machines are all self-designed by DIY. We have been working on machines for many years. I really want to incorporate my ideas into the machines, so we have this machine. First of all, everyone must have a lot of heat for the first image of the Class A machine. Yes, the power tube of the Class A machine works during the entire cycle, regardless of whether there is a signal input, the tube is always working. For this reason, the Class A power amplifier is required to dissipate heat. It must be large enough, especially for the 1969 power amplifier, because the power and sound quality of the 1969 power amplifier are subject to the current. When the voltage remains the same, according to the usual practice of good sound, the higher the current is,
