Question about Technics Audio Players & Recorders
I'm not Shure what you mean when you say "impossible to order". There are plenty of internet suppliers you just need to type in AN7073, to Google to find them. Because the device is widely available it's unlikely to have a replacement type just yet. In any case not all equivalents are suitable. And often it's best to fit the actual type even if you can find a cheaper version. I recommend you contact Technics. They should be able to overcome whatever problem you have in getting the part delivered.

Without a Sams Photofact or a service manual I would go directly to the Power IC which is the largest Integrated Circuit mounted to a large heat sink. If you see any fuses they are probably for the power supply since any fused circuit on the speaker output would be ineffective because the IC would be damaged before the fuse would blow, but you need to check them anyway. Since the short was at the speaker output your problem should be at the final stage of amplification, which is the Power Amp IC. Prior to the early 70's you would have transistors mounted to a heat sink which could be individually checked and replaced. Then manufactures started to use the Power Amp IC which are more costly but eliminate having to find matched pair transistors. All you can check on the Power Amp IC is if you have an input using an oscilloscope or signal tracer and the power to the IC. If you have an input signal and power to the device with no output, I would replace the IC. Unless you have a test circuit for the IC you cannot test it completely unless you have a device like a Huntron Tracker or build a test circuit using a signal generator and a power supply to measure the gain of the IC with an oscilloscope. Short of ordering a service manual this is a good place to start.
