Hi. 
 
I just tried replacing the stock tube amp on my Bravo Ocean with a Gold Lion ECC82 B749 12AU7 (saw it recommended else where. Not sure if it was the best choice, but i have the tube now, so i guess it doesn't matter anymore), and now it seems the left channel no longer works. Prior to replacing the tube, i noticed that the left channel would sometimes not work after turning the amp on, but unplugging and plugging the RCA cable back in always fixed it so i figured it was the fault of the cable itself and i'd just have to replace it at some point. I suppose it wasn't the cable after all and by opening the amp i finished braking whatever was already faulty. I tried using the 3.5 mm TRS input, and it does the same thing, so i guess i can rule out the RCA inputs altogether. 
 
I'm now looking at the inside of the amp but all i can tell is that no capacitor seems blown, and there are no fuses to begin with. I'm planning to take it to a local repair shop anyway, but it would help if i could identify the problem beforehand, since i have no idea whether they have any experience with those type of amps. 
 
Thanks in advance.

Does anybody have an idea at all? I would hate to have to buy a new amp.

I hope you solved this. I had the same problem. Keep rolling in different tubes. One will work. My Gold Lion couldn’t open the left channel either. Weird glitch somewhere in the design.
