• Manufacturer Part Number: SL1027P
• Description: DUAL PREAMPLIFIER WITH ALC
• Manufacturer: AUK corp

2. Closed-loop Gain (f=1kHz)
3. Oscillation
When the closed-loop gain of amplifier is lowered, oscillation with occur. So the circuit
should be compensated by connecting of 10pF between pin 3 and pin 2, and 0.03 ㎌ in
series with 10Ω to the load end.
• Playback amplifier gain
• Closed loop voltage gain
• Recording amplifier gian
