SIEL Mono
---------
DESCRIPTION
These are the schematics of the SIEL Mono, scanned at 300 DPI.
Some parts are hard to read but the original is not exactly spotless
either. Drop me a mail if you're having trouble, I'll help you if I
can.
Still missing : implantation diagram (probably not very useful),
user's manual (almost useless).

[1]LM3046
On mine (S/N 190/156), ICc4 is not an LM3046 but an FUA3086DC;
8116 KOREA in a 14-pin cerdip package. That would be Fairchild's
version of the CA3086/LM3086 which is an untested CA3046/LM3046.

ERRATA & NOTES
contacts_1.png
According to a Mono owner named Jesper, the keyboard diodes are
backwards in the schematics. He realised this while MIDIfying
his :

In the VCF high pass output there is a missing connection
between the line going from Rf103 to Rf112 and the line going
from Rf102 to Rf104. The correct schematic is :
