Hi!
I'm making new tube preamp, and i'm not sure how to design good p2p layout. Preamp have two tube stages, each tube is decoupled with two caps in paralell.
In general i understand how to make proper grounding, but i'm not sure how to connect each stage to my central star ground.
I thought about wiring all components of the first tube to the bottom of soldering strip (bus grounding), repeat this for the second stage, connect both stages, and run this wire from the end of second stage to my central ground.
To not have B+ wires near input wires, i would have input, cathode, coupling, feedback etc on one strip board, B+ and decoupling on the other. It will look like this:
B+, decoupling
-----------------------strip board
tube tube
input, cathode, coupling, feedback etc
------------s. board ------------s. board
Now, the problem is that my decoupling caps need to be grounded, and i don't know if i should run this wire to the bottom strip board, because than it makes no sense to separate the boards.
So, what do you think about my plan? Should i simply make all connections of each stage on one strip board or not? If i make it this way, it would look like this:

I hope you understand what i'm asking, i had problems with the language when writing this..
