[QUOTE="Timber_MG, post: 89391, member: 18"] I have fired up ye goode olde Wallins jig (Mk1 which isn't even documented on the net anymore, I had to hunt for documentation on my old PC) and measured the B3N. The notch filter has an impedance peak around 6 kHz, so I'll have to check out what's going on there (Zaph's is at 8 kHz). The caps were marked 250V 335K and F105K & 100MEF1 respectively so I am assuming that the driver might have a higher inductance or some values are off.
