The VCO itself (the right-hand op amp) looks fairly conventional. However, the left-hand op amp and the diodes look weird to me. If I were you, I'd try hooking the control voltage directly to the + input of the right hand op amp and omit the rest of it. If you have an LM331 on hand, you can just use that. - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
