Rix,
you have twisted the low level inputs, but left a big loop just before the PCB.
All the high currents wire pairs/triplets are untwisted. BIG loops.

Ahh, ok thanks to be honest i hadn't realized before that twisting/not twisting wires could effect anything.

I've heard of twisting signal wires but not power wires. What's the benefit? Now I need to crack my B1/F5 open and do that.

Receiving aerials ans transmitting aerials.

Make the Transmitter strong enough and everything will pick it up.

Make the Receiver weak enough and nothing will get picked up.
Treat both sides of transmit/receive.

I think this is where having an oscilloscope would be nice and detecting any difference in wires, cheers

Im still wondering what those components are in the Red/black amp i posted at the beginning of this thread if anyone knows ? the red boxes left and right of the PSU. and what that power switch lead covering could be made of ?

It looks like braided polyester and heatshrink sleaving available from Kayfast on ebay or I would think Maplins also.

Thanks it seems so, just liked the look of that one.
My friends wondering if the B1 with F5 will be loud enough driven probably from CD player my guess is yes.. of corse theres the other option to build one of the Class-A pre's like Bride of Zen.

Has anyone had a problem with it not being loud enough ?
I know i could Decrease the feedback like some have done for that extra push.
how about
BOZ -> B1 -> F5
or do i not need B1 if i have BOZ
