They 25k pot should have a 253 on it.
The 250k should have a 254.

So the 25k should have some numbers similar this RV4N253C

I usualy just check them with my meter

Measure them and put the rotation in the middle. For Audio you will have about 10% of the value from wiper to element on one side and 90% on the other. (watch out for reverse audio if it is surplus) I always measure since most pots have a 20% value tolerance. You want to try something really fun try and plot the resistance. Audio pots are usually not very smooth curves.
