What should the values be?
Standard values for Zobell NET, as follows:
![[Image: attachment.php?aid=38488]](https://forum.yu3ma.net/attachment.php?aid=38488)
Use 1mm CuL (classic enamelled copper wire) wound around AAA battery (DIA = 10mm),
wound a single layer coil with 10 of the turns appro. 10mm in coil length,
then place a 10R 2W resistor in the middle of the coil, but it must not touch the wire of the coil.
The Air coil is such appro. 0,9...1,0uH // 10R in value!
Onto this little PCB I have ten wraps of 1mm magnet wire around an AAA battery with a 10 ohm 3 watt resistor inside of it, parallel off the end of it to ground I have a Vishay 0.1uf 250VDC poly film cap and another 10 ohm 3 watt resistor.
(not soldered yet, waiting input that this looks alright)
Output will come from amp board, to speaker protect, to output inductor/resistor on little board to positive speaker output terminal.
Ground from speaker output terminal, to negative of zobel, to ground of PSU.
Does this look good or a mess?
Thank you, David.
