Yellow Jacket Tube Converters

Yellow Jacket® tube converters allow EL84 power tubes to be used in place of the most common guitar amp power tubes, including 6L6, EL34, 6V6, 7027, 6550, and 7591. Most Yellow Jacket® converters provide a substantial output power reduction and a "self-bias" Class A configuration for the EL84 so that no bias adjustment is required. Yellow Jacket® converters are like getting a whole new amp.
