Thank you Mark.
I think that will be the Goal.
May I ask whats your preferred filter rating for 4xEL84 Rocket?

Also increasing the 8uf caps to 20-22uf has been good.
On my Zwreck I also used a Hammond 159Q choke 7h 150mA DC but on others I used the Hammond 158L.
Hi,
I have the 158L.
My chain is now 60/47//22/22/22
But I don`t understand: "Also increasing the 8uf caps to 20-22uf has been good".
I´m thinking about decreasing from 22 to 8µF to make it softer, a whole step down.
I want to try 40/22/8/8/8 or is the 22µF for screens to much down?
I dont want to try out too much in a ready and compact amp. At the end there will be a bomb crate. Thats not my Intention
Best

Hi,
I use only 1k at screens. A recti tube with bigger voltage drop is a good idea too. I´m shure the amp would like lower voltage.
But filter chain is now my first aim.
I´m running the cathodes with 100 Ohm /220µF each side. Its pretty on the edge but screen dissipation is the buffer
I will write how it turned out.
Thank you
Hans-Jörg
Edit:
Sorry. but which one is the mid cap in the Rocket: C6 or C7? I think C6 but not shure.

- by schematic, but the layout irritates me and I changed to C6
