Horizontal Deflection Module
This board is located between the green and blue tubes.
For this you'll need a good soldering tool, solder and a 220 mfd @ 160vdc cap (C50). And remember that we clean each board as we go with denatured alcohol.Replace "C50" it's in the modulator circuit on that board, The modulator circuit supplies the operating voltages for the deflection power stage (power MOSFETs), this circuit varies the voltage for the FETs based on the scan rate that the project receives. If this cap leaks, it'll cause erratic width performance, or inability to achieve max horizontal width.
