There are two types of mechanisms used in this model.
While the previous SERVICE MANUAL <No.YF075> features existing <YMA0029 series>, this SERVICE MANUAL <No.YF075B>
features <YMB0051 series>.The<YMB0051 series> is a new type of DVC mechanism.
For the distinguishing methods, refer to “How to distinguish the two types”.
For disassembling methods, refer to the SERVICE MANUAL <YF081>.
Regarding service information other than these sections, refer to the service manual No. YF075 (GR-D290US).
<How to distinguish the two types>
1.Distinction by checking the Rating Label
If the new mechanism <YMB0051 series> is used, “2” is marked in the upper right part of the Rating Label.
2.Distinction by checking the actual model
Open the CASSETTE COVER, and check the CASSETTE
HOUSING.
If the model uses the new mechanism <YMB0051 series>,
“PUSH” is marked in the near right part of the CASSETTE
HOUSING surface.

CHARTS AND DIAGRAMS
NOTES OF SCHEMATIC DIAGRAM
Safety precautions
The Components indentified by the symbol are
critical for safety. For continued safety, replace safety
critical components only with manufacturer's recommended parts.
1. Units of components on the schematic diagram
Unless otherwise specified.
1) All resistance values are in ohm. 1/6 W, 1/8 W (refer to
parts list).
Chip resistors are 1/16 W.
K: KΩ(1000Ω), M: MΩ (1000KΩ)
2) All capacitance values are in µF, (P: PF).
3) All inductance values are in µH, (m: mH).
4) All diodes are 1SS133, MA165 or 1N4148M (refer to parts
list).
Note: The Parts Number, value and rated voltage etc. in
the Schematic Diagram are for references only.
When replacing the parts, refer to the Parts List.
2. Indications of control voltage
AUX : Active at high.
AUX or AUX(L) : Active at low.
!
4. Voltage measurement
1) Regulator (DC/DC CONV) circuits
REC : Colour bar signal.
PB : Alignment tape (Colour bar).
— : Unmeasurable or unnecessary to measure.
2) Indication on schematic diagram
Voltage indications for REC and PB mode on the schematic diagram are as shown below.
