Dr. Mabuce's Wogglebug Mod Schematics

2003-01-03 by xamboldt

Wiardos:

If you check the Files section you'll now find a 150dpi jpeg featuring
schematics for Dr. Mabuce's Wogglebug #3 mods. These schematics cover the
first 3 mods he mentioned in a discussion a little while back. To refresh
your memories, here's what they do:

1-addition of a switch that switches-in other values for caps C6 & C7
independently.
2-a separate control circuit (CV/Knob whatever) for VC1 (VTL5C3/2 vactrol)
3-enhanced and independent control of the U5 (555 astable) clock circuit
which included it's own "private" S/H-controlled rate that samples the same
buffered sawtooth as U1 (LF398) does

Many thanks to the kind doctor for taking the time to jot these down and
mail them to me so I could scan 'em.

Enjoy!
