Replacing a Field Coil with a PM Speaker - Please Help
#3

BDI

Since it is a bit of a pain to try to see these images on my tablet, here is the general idea: replace the field coil with a resistor of the same or greater value that is the ohmic resistance of the coil. The power rating should be adequate, that is whatever the voltage drop is, U-square times R applies and then make it 2 times that.

The capacitor after the coil could i crease as due to the lack of the inductance the ripple will i crease and so will the hum.
There is pratxically no change in wiring other than that coil for resistor swap.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
