1. Notice:

The following safety precautions must be followed to assure
continued reliability and safety against fire and shock hazard:

1) Replacement parts used during servicing of this appliance
must have identical characteristics as those offered and
recommended by H. E. Scott, Inc.

2) Satisfactory and approved service procedures dictate that
ALL PARTS, no matter how apparently unimportant, be replaced
exactly as in the original design.

EXAMPLES:
a) Braided glass tubing over resistors.
b) Heatsinks on transistors.
c) Ceramic tube spacers.
d) All mechanical parts, i.e. covers, brackets, etc.

3) A dielectric test is to be performed on each appliance
following the re-assembly and before returning the unit to
the customer.

4) The dielectric test, to be performed on H. H. Scott, Inc.
electronic components serviced in the U. S. and Canada for
use in these countries, shall consist of not less than the
following:*

1) A dielectric tester designed to supply not less than 1100
volts at 60 Hz and employing leakage current indicator/s
is to be used.

2) The tester is to be connected per the instructions enclosed
with the instrument, or as follows:

a) The tester is connected to the power line receptacle,
and the power switch is turned on.

b) Sufficient time is allowed for the tester supply to
stabilize and then the output voltage is adjusted for
1080 volts.

c) Leads of the tester, usually marked GND and RV, are
connected between chassis ground and both blades of
the male plug of the power cord.

d) Switch tester to "test" and observe leakage indicator.
LEAKAGE CURRENT MUST NOT EXCEED 0.5 EA.
* Dielectric tests made by service personnel in countries other than

United States and Canada must use test equipment and procedures
specified by the safety agency serving that country.

CAUTION: Remove head shell from tone arm before applying dielectric test.
