BLOCK DIAGRAM

Service Technology (Part 1)
Note

1. Refer to the circuit diagram and block diagram.

2. “L” and “H denote TTL positive logic, while the figures in circles denote IC pin terminal numbers and printed circuit board terminal numbers.

3. FF denotes flip-flop.
   Play operation
   • When ICla (2) is dropped to “L” level, ICla (12) is switched over to “H and IC 1 b ( 6) is switched to “H” to turn X203 on, the main gear drive motor is started.
   • When IC2b ( 4) is dropped to “L” level and IC2b ( 6) switched to “H level to turn X204, the record size selector solenoid is actived.
   • When the main gear drive motor is started, the main gear is rotated and SW7 gear switch is turned on.
   • When the main gear switch is turned on, IClc (11) is switched over to “L” and IC 1 c (8)is switched to “H’ to turn X207 on, the turntable platter drive motor is started.
   • When the main gear is rotated, the tonearm is operated and the tonearm switch is turned on.
   • When the IC5a (1) input of oscillator circuit is switched “H’ level, it’s circuit is operated, thereby the play indicator repeat to turn on and off.
   • When the rotation of main gear is finished, the gear switched restores R-F flip-flops to the initial condition and the play indicator is turned on.

4. Reject Operation
   • When1C1b(3) is dropped to “L” level and IC1b (6) switched to “H’ to turn X203 on, the main gear drive motor is again started up.
   • When IC2c (I 0) is dropped to “L” level, IC2c (8) is switched to “H” and IC2b (6) to “L” to cut X204 off, thereby inhibiting the record size selector solenoid.

5. Repeat Operation
   • When IC4c (10) is dropped to “L level, IC4c (8) is switched to “H’ and IC3b (5) kept at “H”. When IC2a (1) is switched to “H’ level, IC2a (12) is dropped to “L” to turn the repeat indicator L.E.D. on. When the tonearm returns automatically at the end of the record, 1C206 (6) generates an H pulse ([1}) which is then inverted by IC3d to become an L pulse. When this pulse is applied to IC1a (1), resulting in ICla (12) being switched to “H level. Thereby when  IC3b (6) switched “L” level, IC2b (6) switch to “H’ to turn X204 on and activate the record size selector solenoid.
   To release the repeat mode, simply press the REJECT key. In this case, IC2a(13) is dropped to “L level, IC2a (12) switched to “H and IC4c(8) to “L’, followed by IC3b(5) being switched to “L” and IC3b(6) to “H Then in conjunction  with the reject operation described above, the repeat mode is released by reject action. In other words, the repeat mode is maintained only as long as IC3b(5) is kept at “H level.

Restoration of Initial Condition
When the main gear drive motor is started up for play or reject operations, the main gear is also rotated. SW7 coupled to the main gear restores two R-S flip-flops initial condition.
Auto-Return
When an eccentric pin of the lead arm coupled to the tone­ arm is inserted between D601 and Q601, it serves as a shut­ off mechanism which turns the Q601 phototransistor off.
The difference in voltage is applied to a comparator via IC206 (3), resulting in the generation of a positive pulse which serves as the comparator output appearing at IC206 (6). This pulse is subjected to rectification and inversion at the CR and IC3a, thereby forming a negative pulse which is applied to IC1a(1). This is then followed by return or repeat operation in the same way as described above.
Manual Play
When the tonearm is raised from the arm reset by hand, the tone arm switch drops IClc(IO) to “L level, resulting in 1Clc(8) being switched to “H” to turn X207 on, thereby starting up the turntable motor by turn on of X207.

Stopping the Turntable Motor

• When the tonearm is returned manually to the arm rest IC 1 c(l 0) is switched instantaneously to “H level and IC 1 c(8) to “L”, thereby turning X207 off to bring the turntable motor to a stop.
• When the main gear starts to rotate during reject or auto­ return mode, the SW7 gear switch is set to “on” position during rotation, and to “off’ position end the end of one revolution. As soon as this single revolution is completed, I  CIc(11) is switched to “H level.

The arm switch is at “off’ position ( on the arm rest) at this time, and IC1c(10) is at “H” level. At the instant that IC1e(8) is switched to “L”, resulting in X207 being cut off to stop the turntable motor.
Power On Reset
When the power switch is turned on, three FFs at X202 time constant circuit are reset to their prescribed initial state.

PARTS LIST

Turntable “Flattens” Warps

Onkyo’s new CP-1030F turntable is a sin­gle-play, fully automatic, direct- drive mod­el with a quartz-lock speed control and a specially designed low- mass carbon-fiber

tonearm said to give optimum results with today’s high-compliance cartridges. Low­ frequency resonance of the arm and a typ­ ical high-compliance cartridge is con­ trolled well enough, according to Onkyo, to allow warped records to be played with a minimum of distortion. In addition, the turn-table has a rated signal-to-noise ratio of 75 dB and wow and flutter less than 0.03% (WRMS). Reliability of the unit is said to be enhanced by the use of an additional motor  dedicated to tonearm functions. A set of LED indicators show what functions are engaged. $315.
