They do indeed make a big difference, I would recommend fitting them. The beads are fitted in the Drains of Q9 to Q16 in the circuit shown in the first post, beads are marked as L9 to L16 - not very clear in the circuit. The beads I used are Electus (Jaycar?) LF1251 or FX1115. They are about 4.2mm diameter x 5mm long the hole in the center is ~ 1.3mm. They need to be small as indicated and just fit over the Drain (center pin). FYI: Found an old pix from Wiseguy showing the Ferrite bead. . Edited 2024-03-08 13:37 by KeepIS
