Tools to be provided.
V.T.V.M.
Oscilloscope and test tape
RCA0321, Pony-806 or Victor-8O1
(Recorded on track 1 and 3 with lkHz and on track 6 with
8kHz)
RCA.323
(Recorded on the full track with 400H2)
Note on adjustment
(1 ) Head core must be cleaned isoprophl alcohol before
adjustment.
l2l fo be careful not to give any damage on the core face.
(3) Adjustment should be performed as indicated.
(4) After adjustment, each adjusted part should be locked
with paint and demagnetized with eracer.
1. HEAD HEIGHT ADJUSTMENT
(1 ) Prepare a test cartridge tape (RCA-321 or Pony€06).
(2) Push the channel selector and index head to track 2
(on 2 channel).
(3) Connect oscilloscope or V.T.V.M. to output current.
(4) Turn the head height adjusting screw (No. B ... See
the tape deck exploded view.) slowly right and left
to find out a null. To be assured of proper setting,
PARTS LIST
NOTES:
1. Part orders must contain Model Number. Part Number and Descriotion.
2. Ordering quantity of screws and/or resistors must be multiple of 10 pcs.
making sure there is a peak on either side of the
null, at the point where the intermediate output is
smallest, tighten the screw for positioning.
(When a tape slips off head face, take out the tape
and put the leaf switch on the power source, then
pushing the selector button up and down, make sure
that the position of the head core is exactly in the
width of the tape guide.)
(5) By changing channel from 4 to 2 again, make sure
that the output on channel 2 is smallest. When the
output on channel 2 is larger than on channel 4,
readjust it as described above (4).
2. AZIMUTH ADJUSTMENT
In case that head is slanting on along theway a tape runs,
to aquire maximum high frequency will be difficult.
The following adjustments will be performed to cope with.
(1) Prepare a test tape cartridge RCA-321.
(2) Using a (a), screw driver, wind the adjustment screw
(No. A) to bring out maximum output on channel 2,
presenting 8kHz.
(3) As head height might be moved by this adjustment,
readjustment will be required to assure the head
position.
