4-10b. Wind L5 per 4-10a. Work with confidence; if you discover that you didn't do
it quite right, it's not hard to un-wind and try again.
Note: remember that the red toroid form is made of powdered iron.
Therefore, handle it with reasonable care so as not to crack or crush it. In
other words, don't assume that it's as though as a steel washer!
4-10c. Install L5 in its position near L3 and L4. Use care to mount it as tightly
against the board as possible. If it wiggles easily, you will experience
unstable reception on Band E.
4-11. Double-check the correctness of your work in step 1-1 through 4-10!
4-12. Check the solder-side of the board for bits of wire or solder trapped between
connections and also for excess wire lengths that need to be trimmed.
4-13. Review the quality of all solder connections. Are they all shiny and cone-
shaped? Did you miss any soldering points? Touch up any questionable
solder point by reheating the connection with a very clean soldering iron tip.
4-14. Use the double-sided adhesive strip to secure the 9-volt battery bracket in the
large open area between C1 and the back of the PC board.
