How
to lower the output impedance:
1.
Take the
(green isolated)
centre tap of the secondary winding off the gap between the coil and
the core.
2.
Dissolder the two leads.
3.
Use an Ohm meter to find out which one of the leads is not connected
to a1. This is necessary to get the windings well phased.
4.
Connect this wire to a1.
5.
Solder the other wire to a2. |
