Everyone who uses the bu 808-dfi and it heats up too much, or shorts out | Definitive solution | Use the transistor (2sc 5902) in place of bu 808, retighten the capacitor (c-419) and place a 100 x 63 volt one, add a 1n 4148 diode in parallel with the c-419, connect the katode to the negative of the capacitor and the anode on the positive, remove the resistor r 426 or r 427 and place a 0.47 obms resistor, tsound is no need to place a heat sink | Ademar Videira sc |
