To chassies SE amp,PSU question

The trafos and rectifiers are going to be on the PSU chassie,an so are the e-lyts for the HV.Should I use some smaller e-lyts at the amp chassie or not?
And the filiament and bias supply,where to put the e-lyts,PSU chassie or amp chassie,or both?Filiament are 4x2 amp.

The main capacitors should always be as close as possible to where they are "functioning". For example the main HV cap should be at the feed to the output transformer etc. with its OV to where the output tube cathode(s) return.

Thus while you can have some smaller caps on the Power Supply Chassis the main caps for the HV, Bias Supplies etc should be on the amp chassis.

Cheers,
Ian
