I have gone for a variation of the 2nd layout to keep the mains cabling relatively simple, and (hopefully) tidy.
I just need to think about the best way to extend the transformer secondary cables now.
Should be back up and running by the weekend.

Definitely option 2. The first one looks a right old mess.
I can't see any difference between the two layouts.

I had problems with the images not showing.
Option 2 makes the mains cabling easier/tidier.
I am just waiting for some parts before I can finish the cabling and fire it back up.
Hopefully the common mode filter will make a difference to my problem, that and further separation from the mains should mean less interference.
Me neither. Just a lucky guess :DQuote:

No hum has been heard, yet.
I could also swear that it sounds better than it did before, but that may just be my bad aural memory.
The hum came back shortly after my post above.
I then started to check my mains and saw that there was an issue in the quality of the mains. After months of not using my BB3, I turned it on again today, for the first time in a long time.
The difference now is that the mains cable feeding the village has been replaced/upgraded.
This caused more problems, as the local transformer could not handle the increased power delivery.
Fast forward until a couple of months ago. A new transformer was installed, and we had a date in February where the connection was going to be made.
Well, that didn’t happen. Until today. A forecast 4 hour power cut, that lasted 5 hours.
I waited a while before I powered up the BB3, and finally when I did, there is not the slightest hint of occasional hum.
So basically this thread can be summarised by “Poor power supply causes phono stage hum and there is very little that can be done about it”.
At least (I hope) I am not far from a happy ending….
Hooray, I like happy endings.
