    Maybe the output bjt is broken, you can start replacing it, Q3 part BCP53-16T1G.

    If it does not work you can replace Q1 part FQT7N10LTF, then Q4 part LND150K1-G and finally U1 part OPA140AIDR.

    You can find the BOM to build the UGL semi fnished board here https://www.thewellaudio.com/wp-content/uploads/TWRPS-UGL-semi-finished-board-BOM.zip
