I found Taiwan seller. Thanks!There was a seller in Taiwan on ebay.com that offered various grades of solder with that chip..his ones were real.
OPA1622 is supposed to be the nearest replacement for LME49990. Cheaper.

Found a post in this thread, from 2017, that listed the contact email at iBasso for ordering a replacement PB-2 battery.
.
I contacted them, and the current price is USD$25 + $10 Shipping/Handling.
.
So, now I've got one on order.
Hmmm. How much was it??
I have recently acquired an Opus#1 and would like to use it with the PB2. The balanced output on the Opus#1 is a 2.5mm TRRS with no ground. How do I hook this up to the PB2 balanced input, would I just leave the ground disconnected?
Hirose 6-Pin Plug | Pin 1 | Right GND | 3.5mm TRS Plug | Sleeve |
Hirose 6-Pin Plug | Pin 2 | R+ | 2.5mm TRRS Plug | Ring 1 |
Hirose 6-Pin Plug | Pin 3 | R- | 2.5mm TRRS Plug | Tip |
Hirose 6-Pin Plug | Pin 4 | Left GND | 3.5mm TRS Plug | Sleeve |
Hirose 6-Pin Plug | Pin 5 | L+ | 2.5mm TRRS Plug | Ring 2 |
Hirose 6-Pin Plug | Pin 6 | L- | 2.5mm TRRS Plug | Sleeve |
Thanks. I will give it a try. Isn't that similar to how A&K build their balanced to XLR cable? If I can't use the ground, because of mode switching, would it still work without the ground?
