[QUOTE="Guest, post: 72518"] No worries: the amp unit is a USB powerd 2 ch head phone amp bought on eBay for around $10 ,old head phone lead wired for stereo. The spk is a handheld uhf mic also bought off eBay for about $15, removed the circut inside and conected 2 wires to the spk, then iv bridged it across both ch by - one ch + the other. Wired in the cut down 4x battery tray to make close to 5v and for the moment pinched a small container from the kitchen. Now that it works realy well I'll redo in into a electronics box with a remote button so when someone's yelling at me I can choose to listen or not :) [/QUOTE]
