V H holding frequency
range becomes large.
Output neutral voltage (VN) shift.
(It is referred that R05=R18, R06=R19, R07=R20)
It may oscillate.

side from a power supply line
It may oscillate.
It may oscillate.
The voltage gain (VG) of
low frequency is
extended. However, the
pop noise at the time of a
power supply injection
also becomes large.
It may oscillate.
Decrease distortion at

The voltage gain (VG) of
low frequency decreases.
Increase distortion at
supply voltage shift
It may oscillate.
V H holding frequency
range becomes narrow.
Short-through current
may increase at high
frequency.
With especially no
problem
It may cause thrmal
runaway
