Circuit Simulation of the Deflection System?
If it were that easy… You could use any regular circuit simulation like Spice or Microcap. The real problem is in obtaining the device models, particularly the horizontal output transistor and the line transformer. Initially you could start with ideal components (switch, inductor) and see if you’ve got the basic component values right. That will give you some basic insight into the working of the circuit, but it is then that the real fun starts. For example, storage time modulation of the HOT is essential for the Phi-2 PLL response… I don’t think you will find any realistic device models for power transistors, so you will have to breadboard and actually measure… Jurb’s Comments on HOT Troubleshooting (From: JURB6006 (jurb6006@aol.com).) The base current is hard to read, but the HDT (Horizontal Drive Transistor) collector waveform can give you a readable picture of it. When you put a scope probe on the base of the HOT, the reading is almost useless, it tells you more about a param
