Connect a frequency counter to either OUTPUT terminal.
Load TEAC YTT-2003 test tape. Set the SPEED switch—
HIGH, and PITCH CONT knob—OFF.
Play the tape. Adjust HIGH SPEED control (see Fig. 2-17) fora
reading of 3,000Hz +5Hz.
. Check the following at the beginning and the end of the tape.
Specifications:
Tape speed deviation. ..........-00- 3,000Hz +30Hz
Tape speed drift 2... .. eee ee een 15Hz
FWD/REV tape speed differential ............. 30Hz
. Change the test tape to a TEAC YTT-2002, and SPEED switch
setting to LOW.
. Repeat steps 3 through 4. Adjust LOW SPEED control if neces-
sary.
. Pull the PITCH CONT knob out. Set SPEED switch HIGH. Play
a YTT-2003 tape.
. Check if the speed variation of at least 3,000Hz +180Hz is ob-
tained when the PITCH CONT knob is rotated fully in both
directions.
. Change the test tape to YTT-2002, SPEED switch setting to
LOW. Repeat step 8.
FAST WINDING SPEED
. Set the deck in vertical position.
. Connect oscilloscope between TP1 test point on the POWER
PCB and ground.
. Thread a TEAC YTT-8013 test tape. In this case, either use of
Tinch reels or. 10inch are permitted provided both left and right
reals are tha same size.
.
During
fast
forward
or
rewind
mode,
adjust
R150(see

so that wavelength displayed on the oscilloscope becomes 7msec.
(Fig.
2-18).

position.
. Check that almost equal value of fast winding speed is obtained
between fast forward and rewind modes.
