I used to have a B&K transistor checker that would sound a tone when the transistor was good or bad. I cant remember the model, but they do exist. It had a large switch that you could change between NPN & PNP, and a cable with hook leads and sockets on the tester. I may still have it. A lot of my older test equipment is packed in boxes here and there. I'd be inclined to go after any electrolytic caps too. They do go bad in transistor circuits. Could also be a bad phono cartridge. Food for thought...
