Yeah seen this. Got it book marked.

I may go for the coax soon but I want to use smaller wire.

I don't know if silver will add anything there. It's mostly servo signals going though. I'd rather go for a shielded connection, like a piece of shielded ribbon. Maybe a separate coax for HF??

Any big sound-changes detected yet, with the blue LED's?

Ray.
Ray there is some little difference, I listened to it all last night with LEDs on. (switch being fitted today with cyan led's).

I will report with findings after weekend. I want to make sure I am right and not just believing it is better. If its worse I will say.

Everything sounded good last night though!!!!

I will get the wife to switch it on and off (without me knowing which position it is in) for the tests.

Hi.

If you are replacing the ribbon, IMO the 2 crucial cables are the +5v supply and the HF signal. If you look at the routing, the +5v is at the end of a run with the uP also taking power - noisy!! Remember, most of the RF board is analog so this +5v should be from a clean source. Similarly, the routing of the HF signal leaves a lot to be desired and is a prime candidate for coax direct to R501. I suggested this earlier in the thread.

Andy

I do like ray's earth point

been looking at the pcb layout to see if i can take the digital earth somewhere else
idea is use star earth on brass bar (main earth)
everthing earths to the bar.

I am not worried about the 5V rails as I am going to build a reg pcb for servo digital 5v , analogue 5v , HF & RF 5v.

I'll source some small coax for RF to HF also.

A star point earth sounds very good indeed.

it was in one of his pictures

Hi Andy,

I scanned the PCB-layout of the CD57/67 PCB. If you want it I can send you a new CD57_67_doc.pdf, just give me a PM.

Ray.
