VALVE INSTALLATION
The amplifiers are shipped without the valves installed. It is necessary to install the
valves prior to operation.
It is essential that the valves are installed correctly or serious damage that is not
covered by the warranty will result. We recommend that your dealer perform
this procedure for you if you are in any way unsure.
FIRSTLY, ENSURE THAT THE AMPLIFIERS ARE NOT CONNECTED TO A MAINS
ELECTRICAL SUPPLY, AND THAT THE POWER CORDS ARE NOT CONNECTED
TO THE AMPLIFIERS.
Now remove the valves that are packed inside the amplifier boxes. Also inspect the
amplifiers to check that nothing has become damaged during transit.
Carefully unwrap the valves. You will find the following: -
4 x 211 valves (two per chassis)
4 x 5R4WGB valves (two per chassis)
2 x 6V6GT valves (one per chassis)
Once again, please understand that it is absolutely vital these valves are fitted
correctly.
Looking from the front of the amplifier install the 211 valves first: -
