I had a noise problem with the 203v. I solved the problem by re tapping the

all mounted on one common heat sink, and after making everything grounded
the same, the noise was gone.
Ah HA! So, the OPPOSITE of my suggestion. But, makes a lot
of sense, if a big chunk of aluminum is floating, but
capacitively coupled to the transistors inside, that could
cause problems.
