I have what probably a dumb question:  It's common for coupling caps in tube amps to be rated at 400 VDC.  In in TUT3 most of the caps are 400 VDC and some are rated at 630 VDC.  When the amp is working with the tubes in the voltages are well below the voltage rating but when testing without the tubes the voltages are close to the V+ and often exceed the voltage rating.  Is this any reason for concern?  

Thanks for the help!

Come in where it's warm!
A warm welcome to tube amp modding fans and those interested in hi-fi audio! Readers of Kevin O'Connor's The Ultimate Tone (TUT) book series form a part of our population. Kevin O'Connor is the creator of the popular Power Scaling methodology for amplifiers.
Please remember these three principles: respect, sharing, community.
