This would massively increase the gain in this part of the circuit. Theres also a small cap in parallel, 100 pf or 47 i think.SWhttps://www.blogger.com/profile/04012077863633210810noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-85108619468955234332021-06-19T16:01:27.185-04:002021-06-19T16:01:27.185-04:00The same thing.
