Re: Trem help needed??
Oh, I looked and see it is an opto type. I was thinking it was a direct drive type trem.  
 
I wouldn't think increasing the drive to the opto could be done to a great extent. The photocell only can go so low.  
 
Where did you move it to, the grid of hte phase splitter? You have a photocell that varies in resistance as it is lit up. You need to get an idea what those resistance ranges are, then look at the resistances in the circuit where you wish to inject it. Then you can figure it out as a variable voltage divider to see what you can do to change its level of effect.  
 
You could also restore the trem to its original location where it worked, But this time make your own custom opto with two photocells instead of just one wrapped around the single bulb. Now connect the second opto to the other channel.
