€6.90 isn't overpriced, and the op-amp looks authentic. Yes, I know there are counterfeits everywhere, but counterfeiting a €3 op-amp and then adding a Class-A output stage to it would be stupid.
uA741 op amps are old school op amps for sale via Farnell for £0.22 each for genuine op amps. The same look a like op amp on ebay for £0.12 and they are fakes.
A fellow engineer bought a batch of them as they were cheap and sent me some as a sample to evaluate. They run hot, are very noisy and have a terrible slew rate.
Even 1N60p (SMD Germanium diodes) turned out to be standard Shottky diodes, not Ge at all! After replying to the supplier, the description changed; https://www.ebay.co.uk/itm/39656015...h6OKRQNyZ96GQDwfzr4VoZUw==|tkp:Bk9SR7yrzffTZQ
I will never trust fleabay as a supplier unless dealing with a trusted known, traceable supplier with a 100% track record.
