9710 VCA assembly problem‏

Post by Nic Roche »

Hi testing after assembly -Step 2 in testing:
"ADSR LED which should be cycling... less than a second"
Our LED cycle is 5 seconds. The instructions deal with no cycling but not a different period of cycling. Can anyone suggest any verification's here.
Regards,

hi nic
guess u did not have any extra parts after assembly? it sure sounds like the problems are similar. a too big of timing capacitor would give much longer/slower lfo speeds. check value of c16 on 9710 and c22 on 9720.
both should be 1uf. a 4.7uf or 10uf or larger would make for a very low lfo.
IF U THINK U GOT A GOOD DEAL....U DID!!
