8. MEASUREMENT AND ADJUSTMENT
— ELECTRICAL —
*Before performing maintenance on this unit, thoroughly clean and demagnetize the entire tape
path. TEAC maintenance equipment to be used:
TEAC TZ-261 for cleaning
TEAC E-3 for demagnetizing or equivalents.
*The electrical adjustment procedure for the A-3300SX and A-2300SX are identical, except that
the tape speeds of the two models are different (15 ips, HIGH and 7-1/2 ips LOW speed for
A-3300SX-2T, and 7-1/2 ips, HIGH and 3-3/4 ips LOW speed for A-2300SX and A-3300SX.)
The checks and adjustments are, unless otherwise indicated, for the left channel at the LOW tape
speed. The same procedures are to be applied for the right channel also and again for both
channels at the HIGH tape speed.
*It is important that the deck be set to proper voltage and frequency for your_locality.
