WARNING HIGH VOLTAGE!
The amplifier works with high voltage up to 3000V which is LETHAL! You should never work
alone in the room and you should always have somebody nearby, who is capable of rendering
FIRST AID in case of any unfortunate accident!
Immediately after having removed the top cover , make sure that no residual DANGEROUS
VOLTAGES are present inside. For the purpose, take approximately 1m (3ft) of WELL
INSULATED wire (adequate for 3000V). Bare and tin about 10-15mm (1/2") on each cable end.
Connect one wire end FIRST to the GROUND STUD (on the rear panel), and AFTERWARDS,
holding the wire BY THE INSULATION ONLY, at a distance of minimum 10cm/4", touch with its
free end the following points on (be ready to see an electrical discharge spark at each point in case
of residual charge presence):
- The spade Fast-
On contact labelled "HV OUT” or “+2850V" on the HV Filter PCB (early
models) or HV&SG PCB (latest models)
– see the pictures below;
- Each lead of the wire-wound resistor R17 (R17F) on the same PCB;
-
Each one of the tubes anode cap.
