If your struggling I'd be happy to help out on a repair. I might pick one of these up myself and see if I can fit a 4.4mm or a 3.5pro in it. I'd be looking to change the dac to an AK4493 and kemet ko cap upgrade at the same time, maybe opamps too.
Depending how much room the battery takes up their maybe room for a 3.5pro, 4.4mm might be pushing it.
