So this sucks!!! My 18 year old receiver's digital inputs stopped working. The receiver in particular is the Denon AVR-4306. It was launched almost 2 decades ago and weighed about 18 kilograms, so you know its got great component for power in it. But any way, there's no much I can do in terms of fixing it now since I can't find the assembly or disassembly sheets on it anywhere. So if you're reading this and know where I can get them, I'd be super thrilled about it!

Let me know in the comments if you can help and if you also feel the same way about high end audio and affordable audio.
