Princeton Reverb Tremelo tweaking

[Toxophilite]

In my latest build (kind of a Princeton deluxe reverb with a  long tailed PI)
I'd like to achieve more tremelo depth and slower speeds if possible
Which component values in the tremelo circuit can I tweak to achieve these things, if possible?

ooops did some research and lot's of info online
Changed a 1m resistor(between the two .02 caps) to 220k =more depth


Changed the .01 cap( connected to the ,02 cap and the speed control) to .02 = slower speed
o might try a .033 at the speed to slow it down further but the results are good so far.
