Someone brought one to an audio meeting recently. He had remounted it in a project box with real speaker terminals and rca jacks, an Alps volume pot, and a 12 volt rechargable battery as the power supply. Couldn't do a proper listen because these meeting are rowdy, but it sounded very nice to me driving a pair of Fostex Voigt pipes and 3rd Rethm Lowther driver speakers.
