Hello again, I found a website that offers the LM386 op-amp for around $0.37. It is on Avnetexpress.avnet.com/store. I know that older IC's are cheap, but is this too cheap? Is that a normal price for a part like that or would it be a bad quality product at that price. I was also wondering if Avnet is a dependable and quality store? And my final question is, can you use the lm386n-4 the same as the lm386n-1. I have built a few circuits with the lm386n-1, so would they also work with the n-4? or do they need more power. Can i just take the n-1 out of the socket and put in an n-4 without making any changes to the circuit and it will still work at ≈1W? Thanks again
