Description

A copy of the 2x30W EL34 tube amplifier: https://easyeda.com/project_view_2x30W-EL34-tube-amplifier_Fjd7pjBTa.htm but redrawn using EasyEDA valve symbols with simulation models and the output transformer modelled so that the whole amplifier (excluding the PSU) can be simulated. The transformer model is the subcircuit that is used for the transformer symbol in the amplifier simulation. To learn how to find and use the symbols used in this simulation and for a list of available spice models, please see: https://easyeda.com/andyfierman/Valve_Tube_examples-05ZhzR9rJ More on valve / tube modelling: [SPICE Models for Vacuum Tube Amplifiers] [SPICE Models for Vacuum Tube Amplifiers]:http://users.ece.gatech.edu/mleach/papers/tubeamp/tubeamp.pdf
