How I Get Music On My Boat (cont'd)

The Regulator irons out the peaks and troughs
As promised, here's more of the set-up used for providing a half-decent sounding hifi system on board the Boat For My Potplants.

Some of you avid sailers out there may baulk at my enthusiasm in this department and cry out "But why don't you take the bloody boat out on the river?". Well, it's a good point, well made, and I will answer my critics all in good time.

Meanwhile, back to the hifi...

The Leisure Battery stores the energy
After the solar panel has collected all that free energy from the sun, it has to transfer it to useable mains power. But as the day becomes night, and there are clouds blocking the sunlight, there are peaks and troughs of energy, so the power has to run through a REGULATOR to make the supply more constant, before it is put into the LEISURE BATTERY.

From the leisure battery, the cable sends the electricity into the cabin and into the INVERTER situated under one of the seats. The inverter turns the 12v supply into 220V, so as to give normal mains power, and any three-point mains plug can be connected, such as my old hifi amplifier.

The Inverter turns 12v into 220v mains power
My hifi amplifier is a 1970's Grundig - a relic from my distant past. But it works well, gives a great sound - and didn't cost anything. And what's brilliant about it is that it has connections and selector switches for TWO pairs of speakers. Oh, what joy.

My old Grundig hifi amp - still going strong since the '70's
So tomorrow, dear blog-readers, our lesson continues with details of the speakers AND the music sources.

Gosh, I've always wanted to be a teacher, and now I am one.
