Schematic - Wlx-896b
The WLX-896B runs hot. If your schematic does not show thermal tracking resistors (e.g., a 100Ω PTC in the bias divider), add one. Otherwise, thermal runaway will destroy the finals. 3.5 Output Low-Pass Filter (7th Order) Typical values for 88-108 MHz (as seen on actual WLX-896B boards):

If you are searching for the , you are likely facing one of three scenarios: your device has blown a final transistor, the power supply is oscillating, or you are attempting a modification to push the unit beyond its stock specifications. The WLX-896B runs hot
Last updated: May 2026. Specifications based on reverse-engineering five distinct WLX-896B units. Proceed at your own risk.

For those who want to modify the WLX-896B for more power: don’t. The PCB traces cannot handle more than 200W. Instead, focus on improving cooling (replace the stock fan with a 120mm Noctua) and increasing the input capacitor bank to 4700µF.
