SA7 PRE-AMP ASSEMBLY PROCEDURE
Soldering 15 parts to a PC board is not a big job, but good performance of the SA7 requires attention to keeping all leads as short and neat as possible. The order of the parts installation is not critical for this and other small kits, so the purpose of following the suggested order of assembly is just to make it as easy as possible for you to get the right parts in the right holes. By the time you build your fourth or fifth SA7 for your neighbors old shortwave set or your aunt's FM radio, you'll be an honorary member of the Ramsey factory assembly line! In working with a small PC board such as the SA7, a miniature vise plus a magnifier may prove very helpful.
