IT'S ALIVE! IT'S ALIVE!! After searching for 2 days (off and on) I have found the microscopic short that kept sending random voltages to the vcos. This was the last problem I had on my to-fix list. I'm sure I'll find more but for now it's working and it's working well. I like it! That's a killer filter. Oh Joy, Oh Joy It's a happy day...;-) Tom
