I can't keep hanging on to all these bits and pieces....
In this listing, a QED Stereo Microphone Amplifier . The unit will also allow connection of a line input (cd player or ther source) and allow switching between the line source and microphone input. It operates from a 12v DC supply but this is not included, and I have therefore not been able to test it.
I have realistic expectations of the value of this item - if you can use it and it's worth the price of shipping to you - you may buy it for 99p!
If you choose to pay by cheque, it will need to clear before dispatch.
