-Increasing output power module for The End Millennium and ZAPSolute power amplifiers.

Extension Modules.
The Terminal ’NPN Basis’ on the main board is connected to the terminal ’NPN Basis’ on the ext.
Board using a 0,5 sqr mm. wire. (Normally white)
The Terminal ’PNP Basis’ on the main board is connected to the terminal ’PNP Basis’ on the ext.
Board using a 0,5 sqr mm. wire. (Normally white)
Power + on the main board is connected to V+ on the ext. Board with a heavy wire.
Power - on the main board is connected to V- on the ext. Board with a heavy wire.
Power Gnd on the main board is connected to Gnd on the ext. Board with a heavy wire.
BDT63 and 1k0 on the ext. Board should NOT be mounted!

If You are using ext. Boards in a 78 or 118 Watt version, to drive a separate bass output ( the
normal thing to do) You should connect a Zobel Network of a 100 nF / 400 V capacitor and a 2,2
Ohms 1 W resistor from Power Gnd to Output on the bass output ( as shown ). If You do not do this,
using the one output with the other unconnected may cause oscillation, dangerous to the amplifiers
health.
