when I finished building and started testing, on step 3 I got "too much" signal wave trace. After searching I found out that problem was broken C5 and C8 adjustable trimmer capacitors. Then, I replaced C5 and C8 with 27pF capacitors and C7 with 100pF as suggested by a forum guy over here, sorry I can't rember your name.
But now I get "not enough" signal wave trace, and what do you guys think I need to do? Should I change C6 or what? Thanks!
