This is normal, just like a stock C64! I would recommend one of these switching 5V regulator replacements:
XP POWER TR10S05: https://www.digikey.com/en/products/deta...05/6707495
CUI VX7805-1000: https://www.digikey.com/en/products/deta...00/7350292
CUI V7805-1000: https://www.digikey.com/en/products/deta...00/1828608
Recom R-78C5.0-1.0: https://www.digikey.com/en/products/deta....0/2652148
ALL of these run cool because they are switching - so no heat or heat sink.
