Teac A-6300 - REEL HEIGHT, FLUTTER, AND TAPE SPEED ADJUSTMENTS

REEL HEIGHT ADJUSTMENT
Reel height Adjustment is required only if a motor has been re¬
placed or if tape rubs excessively against the reel flanges.
Adjustment is accomplished by loosening the reel set screws and moving
the reel table on the motor shaft as shown in the illustration below.
Remove the wooden panel on the right side of the deck for access to
the Set Screws in the reel motor shaft. Reel table should be adjusted
using standard 7" reels. With a tape loaded on the machine, position
the reel table height for smooth tape travel. Be sure to tighten the
Set Screws after adjustment is made.

FLUTTER -
Flutter should be measured in playback mode using a TEAC flutter
free tape YTT-2004 (15ips), YTT-2003 (7-l/2ips), YTT-2002 (3-3/4ips)
and MEGURO model MK-665B 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% (RMS)
7-l/2ips: 0.18% (RMS)
3-3/4ips: 0.20% (RMS)
These figures apply to any tape position and direction (such as
full take-up reel, full supply reel or about mid point).
If there is excessive wow and flutter, examine the pinch roller,
belt, motors, capstan shaft, and reel rest for "grease", "oil",
"dirt" and/or "wear". Also examine the tape counter ass'y for
evenness of operation.
TAPE SPEED -
The tape speed should be measured
using TEAC flutter free tape, Model
YTT-2004 (15 ips), YTT-2003 (7-1/2
ips), YTT 2002 (3-3/4 ips). These
tapes contain a highly accurate 3 kHz
tone. Connect a digital frequency
counter to either line OUTPUT jack.
The indicated frequency should be 3 kHz
(± 30 Hz or less) for both speeds.
