PREAMP & REVERB AMPLIFIER
BOARD
This board
Section 1 v
Expression ar
;scribed in two
sections;
; Pre Amplifier for the
put of The Main Amplifier
I be the Reverb
Amplifier.
1. The
signals from
PA-33(B)
and
the power supply
to
PA-33IB) are connected to J80T.
This signal is
amplified by transistors 01 and Q2,
and connected
to
Expression Pedal through J802,
and the volume
of this
signal is controlled by Exp.
Pedal. This signal
through
transistor Q3 is added to
Ext. Input signal
amplified by
Q4 on Master Volume in
Lower
right-hand
End Block, and the signal is
output
through Q5,
its level set by VR1. The
Brilliance Pot.
is
connected to J806 pin 4, The
Brilliance Pot. is
located on Lower right-hand
End Block.
