THIS IS DANGEROUS.
The danger lies not in the voltage, but in the enormous currents that will flow if the capacitor terminals are shorted. A small screwdriver will simply disappear in a violent explosion. The main bodily danger is from metal watchstraps, etc. Serious burns are very likely if these contact the capacitor.
For safety reasons, the reservoir capacitors are discharged at switchoff by bleeder resistors R9 and R47; this takes about 30 seconds. Red warning LEDs on the PCB are ON when the capacitors are charged.
Fuse Replacement
The 32A fuses mounted on either side of the transformer must be replaced with identical parts only. Soundcraft part number ZD8900.
F1, located on the voltage selector PCB, must be replaced with an identical part. Soundcraft part number ZD8112.
