Please note on pictorial diagram #1 the identification of
the various parts and their respective terminal numbers. These
identifications will be us ed when specifying connections.

Make the following connections from the output trans-

l.

2.

8.

Connect blue wire to pin 3 of V2 (S).
Connect green wire to pin 4 of V2.

Connect blue-white wire to pin 3 of V1 (S).
Connect green-white wire to pin 4 of V1 (S).
Connect red wire to condenser lug 2.
Connect yellow wire to screw terminal 3.

Connect orange wire to screw terminal 2 (S).

(If the 4 ohm Dynakit is being assembled, the brown
wire is the 4 ohm lead. It should be connected to
screw terminal 2 (S). The end of the orange wire
should be taped and this lead left loose inside the
chassis. With this arrangement the output impedances
are 4 and 16 ohms. A shift to 8 and 16 output can be
made at any time by interchanging orange and brown
leads).

Connect black wire to screw terminal 1.

Mount P-782 transformer with #3 screws, nuts and lock-
See pictorial diagram #1 for correct orientation of trans-
former lead colors below the chassis.

Make the following connections:

1.

Connect long black wire to switch lug l (S).
Connect short black wire to lug terminal 1.
Connect one red wire to pin 4 of V3 (5).
Connect another red wire to pin 6 of V3 (S).
Connect one yellow wire to pin 2 of V3 (S).
Connect another yellow wire to pin 8 of V3.
Connect red-yellow wire to lug terminal 3.
Connect red-black wire to positive lug on

selenium rectifier (S). This is the lug
nearest the chassis.

, Twist the two green wire tightly together and

connect one to pin 2 and the other to pin 7 of V2.
