I have posted a thread in the Sheffield section of the forum, but haven't yet had a response.

I need to borrow a battery powered amplifier if possible, for next weekend (Friday 2nd October), for my stint on the fourth plinth in Trafalgar Square.

If anyone can help me out, I'd be eternally grateful!

Thanks

Alex
