Sure thing. If it still powers on and you can see the internals without tearing it apart, it’s worth the effort. Those old transistor packs and vacuum tubes are a lot of work to replace, but getting it humming again can feel like a good job done. If it’s dead and the parts are hard to find, you might as well hand it over to a collector or just keep it as a display piece. Either way, it’s about what you get out of it.
