Hi - I recently bought this suitcase record player-cassette-radio. Not a boombox, but in the same family - portable works on batteries and it's big! The only part missing is one of the knobs for the sliders.

here is a link to some images of this model (not mine - look toward the center of the page): http://produto.mercadolivre.co...ima-e-impecavel--_JM

and here are links to what the knob looks like:
