Would Volt regulator IC contribute harsh sound(IMD) ?

Posted by Eric Chan on February 8, 2017 at 19:45:30:
I had the following post regarding harsh sound existing on the BAT 6h30+6c33c amp, harsh sound go away after 2.5hour warm up.

Lot of advice said it should have taken that long to warm up, possibly some other peripherial circuit, I narrow down to input stage PS regulator and recitfier, but not sure my next action to experiment the replacement for Regulator IC or rectifier worth the effort
