Check space available before ordering.

For cap after rectififer,: use a single Clarity film cap any where from 10uf to 33uf

The main B+ cap: use a single 100uf or two 45uf Clarity film caps in parrallel

Use 33uf or 45uf film caps for each RC filters feeding the 6sn7 and 5687 stage

The 10uf 160v cap on the PS does nothing to the sound. Dont bother with it.

One word of advice, you are looking at fitting 6-7 caps underneath the chassis in non-optimal positions with all the messy wiring.... I would not do it.

If you are a real fiddler, you could try to different 300b filament heating methods. Many has agreed on various forums that this is one area a 300b amplifier can be improved the most. Do some research.
