Re: [motm] The great 300 VCO Completed and Suggestion

2001-01-02 by Dave Hylander

Jim,

Which one are you asking about?  Larry's VCO tuning mod, or the R50 change 
to 2m2?  Most likely your VCO's already have the change of R50 to 
2m2.  This change was recommended to improve 1V/OCT scaling.  You can check 
your VCO - look at R50 and it should be Red,Red,Green.  Paul commented that 
this change is NOT necessary unless you feel that your 1V/OCT scaling needs 
to be improved.

If it's Larry's mod, check out the link in his email first.  To do this 
mod, first you'll need the proper tools, a solder sucker, a small soldering 
iron with around 700 degree capability, an Xacto knife or similar to cut 
the trace, no clean solder, and the resistor.  A multimeter or continuity 
tester would be nice to have to be sure you have actually cut thru the 
trace.  After you check out Larry's page and you need more info email me 
privately, and I'll get you set up.
