The T-30B is a switching supply, and there is evidence that noise
from switching supplies causes both AM and PM noise on the 10MHz
output of a TBolt. See:

For best results, you may want to use a linear supply instead. The
Power One HTAA-16W-A is one popular linear supply for use with the
TBolt. They are often available very reasonably on ebay. I believe
there is an identical or near-identical Condor model, but I do not
know that part number. For use with a TBolt, the HTAA-16W-A benefits
from a very simple modification to allow full voltage to the oven at
startup (otherwise, the 12v supply is current-limited when the TBolt
is first powered up from cold):
