Teac A-3340 - MECHANICAL SPECIFICATIONS AND PERFORMANCE; REEL HEIGHT ADJUSTMENT; FLUTTER MEASUREMENT; TAPE SPEED MEASUREMENT

REEL HEIGHT ADJUSTMENT
Reel. height adjustment is required only if a motor has been
replaced.
Adjustment is accomplished by loosening the two set screws
in the reel turntable collar.
Reel turntable height should be adjusted using standard 7"
reels, if 10" reels are used place a TEAC reel height ad-
justing sheet on each reel turntable.
With a tape threaded on the machine, position the reel height
for smooth tape travel. Retighten set screws.
* Reel turntable, if damaged should be replaced as a unit
available only as a complete assembly. :

Height Adjustment
FLUTTER
Flutter should be measured in playback mode using a TEAC flutter
free tape YTT-2004-2003:2002 and a Sentinel Inc model FL~3D-1
flutter meter.
Measurement of flutter should be made in accordance with NAB
standards.
Values obtained with different standards or equipment cannot be
compared.
Flutter should not exceed. 15ips: 0.15%
7-1/2ips: 0.20%
3-3/4ips: 0.25%
These figures apply to any tape position and direction(such as
full take-up reel, full supply reelor about mid point).
TAPE SPEED
The tape speed should be measured
using TEAC flutter free tape, model
YTT~2003+2002. These tapes contain
a highly accurate 3 kHz tone.
Connect a digital frequency counter
to either line LINE OUT jack.
The indicated frequency should be 3 : * oy
kHz 0.7% for all speeds. Fig. 6-6 Test Equipment Set-Up
