 ""I find the Astron SS-30 is generating all sorts of noise. ""

For the past year, I have used an Astron RS-35A (linear = heavy) with excellent electrical results.  Just yesterday, I removed the power transformer mounting screws and added rubber equipment feet as isolators and remounted the transformer. This eliminated the annoying audible (not electrical) hum that I had been putting up with all this time.
