Looking through the VT80+ schematic C184 & C185 are near the speaker output. Obviously they are different circuits but I am curious where in the circuit those two capacitors are located on your amp board. Look at page 4 quadrant H2 of the VT80+ schematic and locate C184 & C185 the 0.68uf 100v film capacitors. Look on your board near the burnt out caps to locate two 1000pf 100v caps (C146 & C147) that run in parallel with those caps. May be a long shot here but perhaps these two schematics share something in common or possibly not. Can't hurt to check.
