ABSTRACT:
A unitary chassis for a full line of television receivers that includes only two circuit boards that contain all receiver circuitry and components designed to facilitate more frequent and easier change from manufacturing one model to another in the line. The boards are generally identified as the power supply board and the signal board and both are slidably mounted in a chassis frame identical for all receivers in the line. Only the circuitry on the boards varies from one model to another and the dimensions of the boards remain the same. The boards are made on two assembly lines and because of uniform board size and the use of common components, these lines can be quickly changed from one model to another. A jack pack is also provided, identical for all models and mounted in the same location on the signal board throughout the line.
