tim,
thanks a million for your reply.
i went back inside the A100 armed with your info and some ideas it
had created.
i had previously checked the links on the A190 also before posting.
the jumper however on the ADSR unit was indeed missing as you had
suggsted so i put one on and problem solved. doh !!!!
with regards to the a110 VCOs,
i had a close inspection of the units and the PCBs, after about 15
minutes of scrutinising i noticed two boxes printed and labelled int
cv. one at the bottom right handside, near to the blue adjustment VR
and the other at the top left near to where the mini jack for cv
comes in.
these were both unconnected to anything and had clearly never been
(holes were perfectly clean, no old solder traces etc) and it was
the same on all three VCOs.
as an experiment i wired them together on one of the units and hey
presto, full cv response.
can anyone confirm that these points should in actual fact have a
wire conencting them together before i go ahead and connect and
solder them properly.
i suspect so but just would like to check.
cheers,
neil
