Heathkit SB-200 audio distortion

[Tom Buchanan]

Hi,
 
I am working on a SB-200 for a winter rebuild project.  I have the amp
working with full output, but the problem is the receiver audio.  The amp
has a new power supply board, soft start and soft key interfaces plus 2 new
electrolytic capacitors under the chassis.   When I turn the amp on, the
radio audio is somewhat distorted and fuzzy. I turn the amp off and the
receiver audio is clear and clean.  Could it be picking up noise from the
fan?  Any ideas?  Thanks.
