Mugig Guitar Amplifier, 25W, Rechargeable Guitar Amp, Support Bluetooth/AUX/USB, 3-Band EQ and Digital DSP Effect, Portable Size for Outdoor Performance, Band Show, Personal Practice

So I purchased the Mugig last year it really is a cool & not bad sounding little amp. There are a lot of cool features on it. I’ve had it a year played it an average amount of time, it’s never left the house. Now it doesn’t work. I took it to be repaired & the service guy said it has a blown output drive circuit board. The hole in it is right where the numbers for the part are and you can’t read it. This unit blew out after only a year with minimal play time! Now I can’t get it fixed!I’m trying to locate someone somewhere that knows how to order the part I need !,, Can anyone help me out ? I see that they are not even available anymore....
