just been reading the service manuals on this site and there is also a EL6472 with 2kw audio output… first page of the manual has this on the front
[ATTACH=CONFIG]81182[/ATTACH]
WARNING:
IN THIS AMPLIFIER THE FOLLOWING VOLTAGES ARE PRESENT
+4750 V: anode supply to final stage
+ 700 V: supply voltages of various preamplifier stages.
When the amplifier has been disconnected from the power, you must wait 1 minute before removing the covers or working inside the amplifier.
During this time the high voltage capacitor C11 discharges itself through R13 and R14
SO BE CAREFUL!
to put this into perspective, an industrial mains power supply is 400V and that big electric train in the other video from NL I posted only uses 1500 V. Also it weighs 245 kilos (so about 4 times as much as I do).
