A small portable household electric fan heater in the style of a '60s Vox amplifier, for credibility in those colder days.

LSH excerpt
http://forums.klips...p/28318/237913.aspx
"We take the original LSH loudspeaker as a point of departure, build a forced-draft box on which to set the LSH, and wire a shunt resistor R2, of 0.1666Ohm rated at 50 W and a series resistor R1 of 3.837 ohms rated at 1200 W. This will give an effective load resistance of 4 ohms and a continous input capacity of 1200 W. .... and so forth. PWK did state that it "will dissipate the heat and keep the house warm. Rated SPL was 100 db at 1 Watt at 61 cm." [csea, Feb 19 2009]

If you promise a bun, you gotta give it! |

I've got a valve radio that doubles as highly efficient heat-source for those long cold nights. |

I'm bound to approve and you know why + |

Paul Klipsch, known for his marvellously efficient horn-type loudspeakers, invented the LSH (Loudspeaker and Space Heater) as a parody of the highly inefficient loudspeakers touted by some of his competitors, and wrote a paper about it in 1974 . I'll try to find a link. |

needs some accessories like ear muffs & foot pedal slippers! |

My Vox amp only has one valve (the rest of it being digital modelling stuff) so it doesn't get very warm, but my other three valve amps all crank out a fair bit of heat otherwise I might well go for one of these. |
