Before we go any further Andy, it appears that you are in need of some basic test equipment and some basic theory. The reason you want to measure the voltage on the caps is to see that you have adequate headroom for the power supply to work properly. The other reason is that a 15 vrms transformer should give an approximate 21 volt peak, That's 15 multiplied by 1.414. An unloaded linear power supply in this application should read about 21 volts DC at the cap after the diode bridge.
I think it would be best for you to pick up on some regulated power supply basics and then post your issues on DIY audio. Best of luck in your future endeavors.
