A large cylindrical transition radiation detector has been constructed as a part of the Venus detector for the TRISTAN e+e- collider. It was designed to supplement the e/π separation capability of the lead glass calorimeter. It is one of the largest transition radiation detector in the world at present. The detector has a total of 2,688 channels of readout electronics. The electronics employs the method of charge sensitive preamplifier-trapezoidal shaping. Each TKO board contains 32 channels of shaper-gated integrators and a 12bit ADC. This paper describes full details of the readout electronics, the electronics for wire-gain control and the performance of the detector.
