Hi folks,
my A-131 exponential VCA was bought in September 1998 (no idea when it
was built. PCB says it´s a version 2 from 1996).
It also uses the PA382. (the other two ICs are Texas Instruments´ TL062)
Look on the PCB (frontplate facing to the left):
-below the PA382 you can read: LIN:3381 LOG:3382
The module overview of my owner´s manual (NOT the service manual) says
"...built with CEM3381 / 3382"
So is the PA382 the same chip as the CEM3382 but with another name Or
is it a totally different IC Dieter, please help!
another look on the PCB:
-above the PA382 I can find a blank field marked "ST2" with ten solder
points (actually that´s two pairs of five solder points marked: + /
ground symbol / triangle symbol / CV / - )
-to the lower right of the PA382 there´s a solder point marked "JOUT /
BOARD 2" .
Florian, you said that you can modify the A-130/131 into two VCAs when
they use CEM chips. Is it then possible with my VCA with these solder
points
bye, Paul
