“i know nothing about this unit other than it lights up. therefore, parts/repair.
it will def need a good cleaning at the least!!
there are no returns on this as a vintage piece, so ask lots of questions, if i can i will answer. this was left to me by my bro when he went in a nursing home. i have no use for it and need it gone to make room for the inevitable more gear. maybe something you can use?” Link
