114th AES Convention 2003, Amsterdam; paper 5748. In earlier preprints new vacuum tube and output transformer equivalent models were proposed. These models are now applied to the famous Quad II valve amplifier. Results of models and measurements are compared in the frequency-time and amplitude domains. It is demonstrated that output transformers and multi grid vacuum tubes and complete vacuum tube amplifiers can be modeled with great precision.
