A vertically placed PCB works best for this, as it is much stronger then, bolted to the back wall of the chassis.

Otherwise, wiring from the relay board to the RCAs in damned fiddly if trying to keep cabling short, I've found.
....yep. and i have just the right vampire connectors for the job.....thanks for the idea, back to the drawing board, might as well do things right.

At least with the secondary ac only, voltage is lower so induced 50hz hum , if any, should be much lower.

I would like to fit it all in....would make a nice clean unit.....:-)
Not having the mains in any audio box is best theoretically. Expecting to see your final build since you are putting much mechanical design and automation effort in it. Wishing success.

The proximity of R and L tracks makes crosstalk acceptable or not ?

here is a snapshot of my present layout of output relays:
Interesting board CeeVee

Because i also want multiple inputs, i have ordered this one:

Input Selector Kit 6-to-1 Way Stereo

Any thoughts about that?

Why don't you put your transformer in the front left corner? So the cables go between the side and the DCB1 filter cap...

yep considering that, .....and if you look a the hifi2000 alu side profile you will notice it has a channel with partial opening to the inside of the box....nice to route cables while shielding them if i earth the box....which i will ofcourse.

Nice dvb...only would check the quality of relay contacts.....that is the only issue of inportance here, i've got omron, nec and nais to choose from, all good.

very cheap board too.

mine is comanded by the display, remote board but otherwise...same thing!

If the relays are genuine, it's good buy for sure.

You bet I'll post for sure.

It's an exercise i enjoy and i can then confortably move on to next build with a feeling of mission accomplished.

It's amazing even with all this simulation in the end there is always something that requires improvisation.....
