YSMA18 - Bargraph replacement
  1. Remove the top cover and the front panel
  2. Remove the old TFK bargraph
  3. Remove the 330nF mylar capacitors, and solder them on the back side of the main board (fig #1).
  4. Install the new bargraph (Steadily apply it to the main pcb to avoid mechanical problems - fig #2)
  5. Test: the bargraph should indicate approximately 0dB when a +6dBm/1KHz sinusoidal signal is present to the output and the output level is calibrated at +6dB.
