Its features and functions
 
■ High-power single-ended tube amp: The output power of LM-508 IA reaches 48W in Class A, which is a high-power model in the single-ended amplifier line. Think of the market's KT88 push-pull tube amplifier, its output power is not so, even so is a good thrust. In the tube amp, the sound of the single-ended amplifier is recognized by the user, and the high-power single-ended amplifier is the object that everyone is chasing, because the driving force under the timbre is also good, and the speaker suitable for matching is wider.

■300B pushes 805 tube: Single-ended tube machine made of 805 tube, the output power can be up to 40W or more, and the 300B with the "dream ball" has a charming sound, but the power output of the power amplifier with its output is only a few Tile, not enough to drive some inefficient speakers, but let it push 805 more than enough, and 805 does need a certain driving force, its input impedance is relatively low, it is suitable to use 300B with lower output impedance as the push tube, so that Let the 805 output 48W of power, no wonder they can be hit, and they use a direct coupling between them, and do not use a coupling transformer.

■ 4-band feedback adjustment: On the right side of the top panel of the LM-508 IA, there is a “NFB” selection button, which provides 4 segments of feedback volume selection. Different feedback quantities can be used to get different sound effects. Choose to use according to your own taste, and support hot machine switching.

■ Bi-level indicator: LM-508 The left-to-left position of the IA panel is two level meters that indicate the level of the output. This function can be switched via the panel “Bias” and “Meter” switches. In addition, the two level meters can be selected to turn on and off the backlight, which can be realized by the panel “BACKLIGHT” switch. When turned on, you can see the warm orange backlight.

■ 3 sets of output terminals with different impedances: There are three sets of output terminals behind the LM-508 IA for speakers with different impedances. In addition to the common 4Ω and 8Ω output terminals, 16Ω output terminals are also available. A speaker with a relatively high impedance.

Process and materials
 
■ The enlarged part is made by traditional scaffolding: this is a well-recognized method of making sound, and it is also the method used by the amplifier. This scaffolding process has high requirements for the production workers. In the past, it was difficult to mass-produce. It is almost by a single person to complete the production of one tube, but Li Magnetic has tailor-made the production line dedicated to the amplifier. It is also the world's advanced tube manufacturing pipeline, and a scientific production process will promote the production efficiency. For the remote control and circuit control part, a printed circuit board is used.
 
■ Abundant power supply: The power transformer of LM-508 IA is made according to the needs of this machine. It is not small, adding a lot of weight to the whole machine. After the secondary output of the transformer is rectified, it is filtered by a high-voltage capacitor to obtain a sufficient power supply, and then LC filtered by a choke coil and a capacitor to obtain a stable and relatively clean power supply.
 
■ Tailor-made output transformer: For the amplifier, the output transformer is a very important part, which is related to the frequency response and other factors. If the transformer is not doing well, the other parts are no good. The LM-508IA uses two high-quality broadband high-quality EI output transformers, and the frequency response of this unit can reach 20Hz-31kHz.
 
■ The used tubes: the input tube and the preamplifier tube are all made of Soviet 6H9C and 6SN7EH tubes, and the 300B push tube and 805 output tube are made by Li magnetic. The fun part of the tube amp is that different brands of tubes can be used to get different sound effects.
