MOTM-100 clicks & pops
1999-10-07 by Paul Schreiber
Yes, TJ is correct: the LF398 chip switches the output in like 100ns and
some modules
will not like this.
As it turns out, I need to re-tool the front panels anyway. So, I can add a
panel pot to add
slew and a switch to select vibrato mode. Both of these can be done but what
will happen
is I will go to a MOTM-101 and have to raise the price $10 to cover the
added costs. I will
have to redo the pcb but this is minor.
The slew rate mod does require an additional op amp so adding this to
current modules is
difficult. There is a VC lag in design now that will work (although
over-kill).
