Have just received the K4005B Amp kit from ESR.Two questions.I have opted for 4x10,000uF smoothing caps,will the transformer 30021(21-0-21,300VA) in conjuction with the 4 caps provide the correct supply voltages for this kit.The next quiery is about the speaker connections on the amplifier.Page 11,section 21.The right speaker connection seems obvious,but why is the left speaker connected + to ground?I have built a few amps using well known kits and modules,this seems a little strange,perhaps you could explain or confirm the connections.Regards Jim Davies.
This was done because you can choose, stereo or mono bridge.
The questions I asked related to the voltages achieved by the charging effect of the smoothing caps and the speaker connections appearing to be reversed(out of phase) have not been answered.Your comments would be appreciated.Jim Davies
2x21VAC/300VA is OK.
