Tremulator depth help

[ljudsystem]

Hi guys

I've built the Demeter Tremulator with an old vtl5c1 I found in my fathers garage. It works but the depth is pretty shallow. Is it possible to increase it with a higher (or lower?) pot?

It should swing from double-strength to less than tenth-strength.

Maybe DC readings would give clues.

You "could" raise C1 to say 100uFd. Now it will take seconds to swing a cycle. Now a meter on IC1 pin 6 will tell if that stage is swinging full range or falling short.
