You can get adapter boards that would be much like the supplied IC. It is just that if you wanted to make another getting the Beken BK1079 IC means buying a bag of fifty. Be worth it if there was three or four people to divide up a purchase of adapter boards & ICs.
If it could be modified to run from 5V provided by a power bank you could use one of those 99p PAM 8403 Class D amplifier boards for 99P. Unless the MC34119 has more gain....
I haven't got so far as to add that extra IC yet.
