You can replace the main power block with an enclosed industrial 48V SMPS (such as a Mean Well LRS-series unit).
If the board runs blazing hot but functional, watch the line closely. If it slowly dips or abruptly drops to zero while the +/-7V rails stay steady, a thermal protection limit is triggering on the primary side controller.

: If the internal wiring or the external output leads are loose, resistance increases at those points, creating localized "hot spots" that can melt plastic.
: Aging internal electrolytic capacitors suffer from increased Equivalent Series Resistance (ESR) over time, which radiates intense heat.
