1. Kit-Pak Container

You assemble your Scottktt right
in the unique Kit-Pak container.
It opens to a self-contained work
table with all parts conveniently
in place i closes like a suit»
case for storage when you are at
working on your kit.

2. No Wires to Cut or Strip

Wires are already cut to the pre-
cise length required . . .even the
insulation is removed at the ends.
This Scott innovation saves hours
of tiresome assembly time . . .
assures professional results.

3. Many Parts Already in Place

Mechanical parts such as ter-

nal strips and tube sockets are
firmly riveted to the chassis at the
factory, This Scott extra gives
more rugged construction . . ,
longer life.

4. Full Color Instruction Book

Accurate assembly of parts is
assured by full-color drawings
illustrating each part exactly as
it appears in the finished kit.
Only a few parts are shown and
explained on each page, avoiding
the possibility of confusion.

LK-12 80-watt Complete Amplifier.

The LK-72 ollcrs the finest performance and
greatest reliability of any integrated stereo
amplifier kit available. Since its introduction
the superb performance of the LK-72 has been
acclaimed by electronic experts and thousands
of enthusiastic kit builders . . . many had
never built a kit belorel

Unlike conventional amplifiers that supply
their rated power output only in the midrange
frequencies, the LK-T2 provides a full 404vatts
(IHFM) per channel down to 20 cps. Distor-
tion is below 0.8% throughout.

The LK»72, like all Scott amplifiers. is com
pletely stable with any type of load or even
with no load. The use of an electrolytic alumi-
num chassis, DC healed preamp tubes. copper
shielded power transformers. and carelully
filtered power supply insure total hum and

LK-48 All-watt stereo amplifier

This deluxe Scott amplifier kit has more than
enough power for the majority of music sys-

are measured to strict ITIFM standards. They
will deliver rated power down to 20 cps. Ac-
tually the LK-48 will deliver 28 watts iIHFM)
per channel at 20 cps.

All the luxury features you expect in H. H.

which is quickly accomplished by an ingenious
hum-null method. .-'i true selldialancing phase

insures that your LK-72 will exceed its cun-
servative specifications.

predecessor (the 111510) . no effort has
been spared to make the building job simple,
a lot of fun. and yet have the builder end up

LT-110 FM Stereo (Multiplex) Tuner
Now you can build your own H. H. Scott
Wide-Band Multiplex Tunor fur flawless re-
ception of new FM Stereo broadcast H. H.
Scott tuners are used for oH-tbe-air monitoring
by virtually every FM Multiplex station in
both The Lniieil States and Canada. You too
can enjoy the advantages of Scott "time-
switching" multiplex circuits which have
clearly demonstrated their superiority over
conventional design. Time-switching" results
in lowest distortion. highest separation, and
flawless tape recording.

The highly critical multiplex and sensitive
silver»p1ati:r.l front end sections are pre-wired
and pre-aligned at the factory. No external
alignment equipment is necessary to achieve
the highest professional performance standards

from this fine tuner. Special shielded Wide-
Band lFs allow stereo separation to match
stringent FCC transmission specifications.
Heaiy layer of pure copper. bonded to the
aluminum chassis. assures years of trouble-
free performance.

The perlormance of the LT-llO is identical to
the famed LT-lO which has been hailed by
critics and customers alike as the most sensi-
tive tuner kit available. Conservatively rated
at 2.2 ,uv sensitivity by Scott. High Fidelity
magazine measured 1.4 iw. and Electronics
Illustrated 1.77 luv. These represent the best
sensitivity measurements either magazine had
ever obtained from a kit. $159.95
