I find that very hard too believe. What are you actually asking Google? What are your search terms. I typed in "audio power amplifier circuit" and selected images. There are pages and pages of possibilities. Pick one that looks good to you. If you want an RF Amp then modify your search.
PS Google is very good but it is not a mind reader and can only respond to specific queries. Possibly you kept using the term "schematic"? Leave it out.
