C7-47pF can be replaced with 33pF, and C9,C10-100pF can be replaced with 22pF without oscilations problems.

Thanks Mile. Using +/-56VDC for AX-14 can it still handle 4 ohms load?

This pcb for NX14V2 is fixed on heatsink, and you soldering outputs on coper side of pcb. Montage outputs is much easy this way.
