M9 current negative feedback after-stage power amplifier blank board, not soldered (Lelin line)
The parts on the picture are only for display, The actual shipment is an empty board. You need to purchase additional parts yourself to install. All you buy is an empty printed circuit board, you must pay attention!
M9 current negative feedback post-amplifier, finished empty board, JEFF ROWLAND MODEL9 line from Lelin, USA. The line overcomes the instability factor of current feedback power amplifier on the market, and the S/N conversion rate is greater than or equal to 300V/S, and the bandwidth is up. 5M, the tone is soft, thick, and the control is good, especially the high frequency analysis is good and slender. The line has perfect speaker protection, zero
The bit servo circuit, the buffer of the front-end input field effect transistor, is suitable for the impedance matching of the front and rear stages, and can be matched with any front-end. After the voltage is amplified, add a first-level buffer to implement high current and low internal resistance. In addition, the board is designed with 4 pairs of high power tubes per channel, field effect K1529/J200 or other transistors (example: A1943/C5200)
Parameters and matching
Motherboard size: 260MM X 65MM X 2MM
As different computer display the colors differently,and the color maybe is little difference from the actual items,but we can guarantee the style is same,but maybe some not same performance on different bodies as on the models.Hope you can understand it.thank you！
