George, Eliminating hum is one of the challenges facing any amplifier design, tube or otherwise. From a build stand point, make sure you followed the grounding layout in the instrutions to the letter. Ground loops can be created even though it looks like it should work electrically. Is the hum comming from only one channel or from both channels equally? If it is from one channel, switch the interconnects left and right at the amp and see if the noise moves to that channel. If it does, it is probably a system ground loop. Try using a "cheeter" plug on various components (an adaptor which bypasses the ground prong on your power cord. You can even try modifying an interconnect to cut the ground connection at one end. Tubes can also cause hum. Try switching them between channels to see if the hum changes. Chances are that the hum is due to how you wired the ground connections internally inside the amp. My V35 is dead quiet. I hope this helps.
