This vintage Coronet Boys 2 transistor radio couldn't fit a modern 9V battery in its tiny compartment. My crazy solution? 3D print an adapter for six LR44 batteries in series to create a "skinny 9V." Yes, alkaline LR44s only have 30% capacity of a carbon-zinc 9V, but when your only alternative is a radio that won't close, sometimes compromises are necessary!
