tube layout
NOTE: EL84 and ECC83 tubes must never be swapped. Inserting ECC83 into the socket intended for
EL84, or vice versa, will result in tube and/or amplifier damage that is not covered by warranty.
Never use excessive force when inserting the tubes into their socket.
Operating Procedure
1. Make sure that you read instructions before attempting to operate your unit.
2. Attach the audio sources and speakers (refer to the picture below).
Never run the amplifier without speakers
connected since that may damage the transformers.
Speaker’s minus terminal should be connected to
the speaker terminal marked as zero (0) and positive terminal should be connected to the terminal that
corresponds to the speaker’s nominal impedance (4 or 8 ohms). If your speaker has nominal impedance of 6
ohms, you can connect it to either of the two outputs. You should try both and select the one that performs
better with your speakers. Make sure to prevent short circuit at the amplifier’s speaker terminals as that will
damage the amplifier
