Good thing the set actaully was $10 and not $100, $100 is a lot to pay for any console set, as is, let alone a farm battery radio. While some have mentioned that it will need the capacitors replaced, it may at some point but my experience has been that farm battery sets will often still work when they are powered up for the first time. That being said I would not have recommended a battery radio for a first project, however so long as you hook up the voltages properly there shouldn't be a problem, start with the "A" voltage first and then the "B" with batteries, but you may have to strip the wires back as the ends are usually knackered.
