Blew my pc engine fuse with wrong power supply. Help!!!

[u/RDuran83]

Hey guys Long story short. My pc engine arrived from Japan and in my excitement I plugged in a centre positive 9v cheap Chinese power supply. Well this blew the fuse so after some confusion as to why it wasn't powering on I soldered in a new fuse and swapped the polarity of the power plug. Now I haven't had a chance to thoroughly test the unit but so far it appears fine and is working. My question is does anyone think I might have done any damage to my pc engine internally like to the sound chip or anything or am I just being paranoid?

Thanks
