oh yeah I see what you are saying.
Update, I am a little layout with the layout, I have done cleaning this week (on the layout) , mostly silkscreen and some corners for acid traps and now it should be ready to be sent out for manufacturing.
Thanks guys, unforunately can't enjoy I only hear noise, I guess I connected well the transistors: upper side both BC140-16 & down side BC160-16?
What do you use as PSU ?
Batteries ?
You have to decouple the PSU with electrolytics, say 1000uF on each line.

Only the cartridge should be connected to the + and - input.
When you connect earth to the - input your short the amp.
For example some Rega turntables have the cartridge - connected to the shield, that wiring does not work with this circuit.
Shield should only be connected to earth but not to the - input.

I don't know is Linn Ekos, I guess like the cart left & gnd left to left RCA and right & with gnd right to right RCA.
I connect the cart to + and - inputs both channels.
Gnd TT is connected to chassis and after connected to gnd circuit.
Only the Earth wire from a LINN/tonearm/cartridge combo goes to gnd, everything else is floating as you'd expect.
My mistake😱 I connected the bases between both BC140 & both BC160 in place of BC140 with BC160, time to fire up again
Can you make a simple drawing how you miss connected ?
Even when the LMs are a bit noisy it should amplify.
