Hi all hope somebody can help ..... I am after a schematic layout for this built up board ...... the reason is I have 24v transformer and I want to connect it so that I have +30v and ground. Presently this board is designed to give +VE and -VE and ground. If I connect AC and ground it works but I am only getting something like 1/4 wave rectification. I want to cut the boards tracks and re connect the -VE bank so that it works as positive.......... the transformer would then connect to each AC input but not ground....
The problem I have is this is dual layer circuit board .... so has anybody built one of these and can they help regarding a general schematic...

Interesting??
The connection below is full-wave. Simply *ignore* the "GND" terminals. As-made, it has to be loaded-up with twice as many 25V caps as you would need with a simpler plan with half as many 50V caps. It is not hard to wire this up without a PCB. However since you are not clear, just do it this way. If it is already full of >24V caps, you are good to go.

Hi here is the circuit ..... the issue I have is that I have a Belleson SPHP positive regulator 19v ...... my transformer is 12 0 12 so if I connect the windings on traffo I get 24v ac.
What my regulator needs is + and ground I don't need -vee side and I could do with isolating -vee capacitors and using them for +vee I am not sure about rectifier I need to make full use of rectification not 1/4 wave.
If I connect as you suggest I will get + 26v rms (ish) and -26v rms approx 52v my regulator will not accept -vee see diagram below....

Hi I have just seen your clip ..... will my regulator go splat if I connect it Vee- (ground)??? Sorry bit of a noobie ...... just do not want to destroy a good regulator ....

I'm not sure you need all those when you use that regulated psu.
The cap bank will draw a lot of current until its charged, could damage the regulator

The regulator is fitted to the output of this supply ..... just using this as a nice smooth low ripple supply to supply the super regulator....see the blleson sketch
