SVT-CL Bass Guitar Amplifier Introduction The harmonically rich sound and legendary performance of the classic Ampeg SVT are redefined in the SVT-CL. This dynamically powerful bass amp delivers a thunderous 300 watts of unsurpassed quality, reliability and tonal flexibility, offering the classic vibrance of tubes as well as contemporary features. Like all Ampeg products, your SVT-CL amplifier is designed by musicians and built using only the best of components.
SVT-CL Bass Guitar Amplifier The Front Panel 1 8 9 1. 0 dB INPUT: The signal output from a passive instrument may be connected to this 1/4" input by means of a shielded instrument cable. 8. 2. -15 dB INPUT: The signal output from an active instrument may be connected to this 1/4" input by means of a shielded instrument cable. FREQUENCY: This control allows you to select the center frequency for the midrange control [7], giving you a choice of five “voices” for the midrange.

The Standby mode allows the tubes to warm or remain warm without high voltage being applied to them. This extends tube life. This switch should be OFF when first turning the amplifier on. Allow the unit to warm up for at least 20 seconds before switching to the ON position.

BIAS SECTION: These two controls and sets of LEDs allow the user to properly bias the power amp. See “Setting Tube Bias” on page 9 for a complete description of how to use this section. 18. SLAVE OUT: This jack receives the same signal that is being sent to the power amp.

SVT-CL Bass Guitar Amplifier Changing the Tubes Tubes wear out in direct proportion to how often and how hard you play your amplifier. Power tubes should be checked at least once a year - more frequently if you use the amplifier nearly every day. When power tubes wear out, the amplifier will begin to grow weak, lack punch, fade up and down, or lose highs and lows. Power tubes work together in a push/pull configuration and should be replaced at the same time with matched or balanced tubes.
SVT-CL Bass Guitar Amplifier The Bias 1 control adjusts the three left (front left, rear left and rear center) power tubes. The Bias 2 control adjusts the three right (front right, rear right, and front center) power tubes. By observing the LEDs as the Bias controls are slowly rotated clockwise, a number of tube problems may be diagnosed by the user as seen in the table below.
