Try this: http://www.aliexpress.com/store/product/FiiO-E12-Spare-parts/1473108_32234108469.html

 

It's from Fiio's own store.

That's surprisingly kinda cheap for a lipo.

 

 

I wonder if you could stuff sparkos opamps in, if there's clearance?

I bought an E12 DIY used a month ago. Tried a bunch of different chips. Suddenly I noticed some background noise with the volume turned down, and then about 6 days ago the amp wouldn't work (blue light flash) except with an AD8620 op-amp. With AD8620 (and either of the stock buffers)the amp functions perfectly, but OPA627's, OPA1611, OPA604, MUSES 01, LM4562, ADA4627-1BRZ and AD797 all do not work and the blue power light flashes if I try to switch to one of those chips.
I'm thinking maybe the battery is almost worn down and the reason AD8620 still works is because it operates at the lowest voltage? I've got 2 new batteries from Fiio on order but could use an experienced opinion.

Does changing the buffer help? What if you use it while plugged in to a power source?

No, it doesn't. And now AD8620 gets the flashing blue light, too. I just tried disconnecting the battery and reconnecting it (power off, of course) and plugged into a power source. So now it's dead in the water. I probably have at least a week until I receive the new batteries.

If you have a volt meter, you can measure the voltage off the battery. It should be above 9.6V. If it is well under 9.6V, then it is pretty much dead.

I'll hit Radio Shack tomorrow. It sounds plausible, though? It was working fine until a week ago when I noticed some distortion noise at low volume with OPA627. What points do I measure with the multi-meter? Thanks for the help, by the way.
