Component group buy for LM4780 Pavel Dudek GB
[LM4780 Pavel Dudek GB]
When I put together all the resistors in pieces I get quite a high price, so I was thinking of doing a group buy of the resistors and possibly some other small parts. What parts are you interested in including in a possible group buy? I intend to keep the price down and not choose any exotic components but still choose good quality.
