separate rectifiers for input and output stages?

Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

Is there an advantage to using a separate tube rectifier for the input stage of a SE amp (shared transformer but separate rectifiers and PS), compared to the usual practice of 1 rectifier and the input stage PS connection "downstream" of the output stage connection? How about compared to a shared transformer but separate rectifiers and PS for each channel? I tried a search but found little on the subject.Perhaps my search terms were too vague. The power transformer is a Hammond 278CX, and I have a separate 18A filament transformer, so having enough current for extra filaments is not an issue.

Even DC heating on the input tube of my 'once were LEAK St20s' helps with quietness. - Timbo in Oz 15:23:29 04/18/17 (0)

was quite commonly done from early 50's to early 60's in better designs.~nT - Cleantimestream 11:27:53 04/14/17 (0)
