 B3. Install R108, 2 ohm (red-black-gold).

 B4. Install C33, .01 uf disc capcitor (marked .01 or 103).

 B5. Install C41, .1 uf disc capacitor (marked .1 or 104).

 B6. Install C34, 470 uf electrolytic. Watch out for correct polarity.

 B7. Similarly, install C29, 330 uf electrolytic.

 B8. Install C37, .01 uf disc capacitor (marked .01 or 103).

 B9. Install NPN transistor Q6. Be sure to have identified it correctly as

one of the five 2N3904 transistors used in your kit, (not one of the

2SC2498 RF transistors) and be sure to orient the flat side as illustrated.

Before soldering, press the transistor as far into its 3 holes as

reasonably possible.

 B10. Install R109, 47K (yellow-violet-orange). Note that this is another of

numerous vertical installations of resistors. The body of such resistors

should be snug against the board at the designated hole, with the other

wire neatly looped into the other hole without needless excess.

 B11. Cut three 8" lengths of hookup wire (or 8" of 3 conductor wire) to

connect the Volume Control to the three points designated on the PC

board. Strip and tin all six ends, referring back to Stage A instructions if

necessary or helpful.

 B12. Refer to the drawing

and correctly interconnect

the Volume Control's

three lugs to the 3

connecting points on the

PC board.

 B13. Use two 8" lengths

of hookup wire (or 8" of 2 conductor wire) to prepare the Speaker

Cable. Neatly strip and tin all 4 ends as in Step B11.

 B14. Solder both wires of one end of this speaker cable to the two

marked points near C37.

 B15. The other two ends of the speaker cable may be connected in any

of the following ways:

Standard:

 To J2, the 3.5 mm miniature speaker jack. The

3.5mm miniature jack is the larger of the two

miniature jacks supplied with your kit.
