RobWilson:
Morning and a happy new year to you  Dave   :wave:


You missed off my transformer lol , Your layout looks allot more efficient / better than mine  :thumbup: , I like the way you laid  out the  regulators .


All the best , Rob   

John Rudd:
Happy new year all.......  :thumbup:

Nicely done Dave... :bow:

Rob, the tranny connections are at the lhs side of the board..... To the left of the bridge...

If I were building it, I'd use a Molex 3 pin plug on the transformer leads, and use a matching 3 pin header on the board...a much neater approach rather than direct wiring but to each his own.... :D

Bluechip:
And a Happy and Prosperous New Year to you Gents ...  :nrocks:

If I were doing it, I'd use a PCB mounting transformer ...   :thumbup:  like this:

but as we seem to be stuck with a snivelling bit of a 3VA Chassis transformer I decided to make the rest of it look a bit Neolithic to suit ...  :lol:  :lol:

A bit nippy here ..  :(  not going out today  .... no sireeeeee

Bluechip:
So, not a chassis transformer ???

Oh well, another wrong idea I've got.  :doh:     I blame Global Warming. I was OK until that kicked in ... must have addled my brain  :scratch:

I've made templates for the CPC trannies .

So it would be quite possible to mount it on the board.
