Cheers- First Post-

On building the '52, Where do the 2x 10n caps go?? I see there is 10n on the solder side, but
no holes? hmm..

Also, What is the difference between transistors 2N3906 and 2N3904?

I found that they both reference this single NTE transistor by mouser..

Can I just use this one NTE for both of these??

Thanks-
