Now let's start building
ˆ 1. Press S1 firmly into its six holes and solder all six pins. The switch fits
the board only one way.
ˆ 2. Install J1 and J2, the RCA-style audio jacks. Solder all 4 points. You'll
notice that the mechanical grounding tabs will take longer to solder.
This is due to the fact that the large metal tab of the component as well
as the "ground plane" of the circuit board must be sufficiently heated to
allow the solder to flow completely. Don't be afraid to leave the
soldering iron on the connection long enough to make a good
connection.
ˆ 3. Install J3, the subminiature phone jack. Solder all three points. Be
gentle and patient in inserting, taking care not to damage the solder
tabs.
ˆ 4. Install controls R1 and R12. Insert the PC mounted control firmly into
its position. Check that the control is pressed in firmly and straight
against the top of the board. Solder the three center pins and then the
two larger mechanical mounting tabs. Use enough solder for a solid,
robust connection.
Also, if you plan to use an enclosure other than the custom Ramsey enclosure
and knob kit, you may wish to locate the controls differently than provided by
the PC board. In this case, the control lugs are wired to the PC board using
your own insulated hookup wire as short as possible for a neat installation.

ˆ 5. Install C8, .01 uf disc [marked .01 or 103 or 10nf]. It is located just
above jack J1.
ˆ
6. Install C9, .001uf disc [marked .001, 102 or 1 nf].
ˆ 7. Install C5, 100 pf disc [marked 100 or 101].
ˆ
8. Install C4, 2200 pf disc [marked 2200, 222 or 2.2 nf].
ˆ 9. Install C6, .01uf disc [marked .01, 103 or 10 nf].
ˆ
10. Install C10, .001uf disc [marked .001, 102 or 1 nf].
ˆ 11. Install L1, 1800uH inductor [a large green cylinder labeled 182].
ˆ
12. Install L2, the other 1800uH inductor [again, marked 182].
