hey my PS is:

5u4g - 40uF oil - 10H choke - 47uf * 3 elna to output tubes.

input tubes tapped right after 3 47uf caps to a droppig resistor to another 47uf section of elna.


i have spare 2 more 2 section 47uf elna caps, 2 RTX caps, 2 infinicaps.

where is best place to put the elnas?

my coupling cap is a oil cap... should i parallel these with the RTX or infinicap? or place these caps as bypass caps on elna's?

hmm.... just looking for thoughts and opinions.

I hope this response doesn't sound rude; I really don't mean to be...

Why depend on other's thoughts and opinions? Why not experiment with various combinations yourself? While you're experimenting, don't overlook removing some of those paralleled caps. You might be surprised.

well of course i will try and experiment... i am just looking to see if it were your amp and components... what would you do?

i will try some stuff then.

i mean is it better to have more capacitance on output stage or input stage etc....

anyways i will try some different things.
