After getting Alans DVD and downloading a frequency generator I need an amp with volume control suitable and wondered if anyone else had tried this |

Chris Paulick was looking around for amps for the same reason. Might find some posts by searching. I've been looking around for a cheap amp I can use for this too. Not long ago I sold a small Crate practice amp that would have been perfect; at least it went to a young girl who needed it to play in church. |

I use the amp built-in an old set of computer speakers. I have it connected to a 4" handheld speaker. I use teh volume control on the front of the speakers to adjust the power. I usually turn it as loud as it will go without distorting.......which isn't that loud, but it works. |

Just about any old amp or receiver from a stereo system will work fine. You need about 20 watts per channel, which can be had with many medium priced old amps. I've seen suitable ones at thrift stores. I have an old Pioneer from the 70s that works fine for this, with the headphone output on a beater iBook running into the Aux input on the receiver. Pat |

You can even get by with 12-15W, or a bit less in a pinch. It takes more power to form patterns on the assembled guitar than the 'free' plates, so it's nice to have the extra power sometimes. |

Thrift store stereo would be the easiest, if you can get one cheaply. Another (similar to the Maplin unit) possibility would be a chip amp or T-amp from eBay - mostly Chinese sellers who ship from HongKong. Cheers John |

I'm asking around at the moment for old hi-fi's a friend thinks he may have an old 20w unit in the loft so I may even get one for free only trouble is that may be 20w at 1000Hz so I'm guessing it'll be around 10w at 500Hz or doesn't it work like that? |

Most of those (solid state) amps have pretty flat response down to 100Hz or so, so you should be OK. The power is rated into a given load, so if the amp will drive a 4 ohm speaker that will be the combo that will give the most power 'out', I think. Anyway, start with something cheap or free- you can always work up from there! Cheers John |

Dave, It's the headphone output port. You can get a cable at Radio Shack with a headphone plug on one and two (though you really only need one for this) RCA male plugs at the other. I don't think the USB port would work directly, though you could use an iMic, but that's 30 or 40 $. Pat |

This one might work. They stop short of using industry standard teminology i.e. 15W RMS, but it does say 15W "continuous power", and these little T-class amps have a good reputation.  Peace, Sanaka |
