Bright switch RD 65 GD-2 circuit

So (Thanks to Lars's comments ) I did the mod from GD 2 to GD 2A for the bright switch and really noticed an improvement ,very useable now. :)
I noticed that the .033 cap I took out was rated at 630 v . Couldnt see that that part of the circuit has that much on it. I only had the .022 in 100 volts which I use to try out . Have I made a mistake here?
Started this as a new topic because one its a really good mod and two I hope for a comment back about the voltage rating on the replaced cap
Cheers
