The Fatman iTube Valve Dock has been designed and manufactured by our partner in the Far East to rigorous quality control standards. When we received the design and prototypes for testing we were astonished at the quality of build and the prototypes all passed our quality processes without exception. Fatman by TL Audio took the decision to work with this specific designer and manufacturer because the cost-savings associated with manufacturing off-shore made the product affordable - a hybrid valve amplifier of this quality would be very difficult to build in the UK and still be viable for this market.
