Pulse Transformer Issues - Need New PT

I ended up switching brands of pulse transformer that I’m using to fire the gates on an SCR-based DC drive.

This new transformer is 100uh more than my previous. Now, however, I'm encountering issues with the trigger circuit. I changed the value of the trigger circuit capacitor but the output of the drive isn’t stable. Any insight would be appreciated.
