I think I am going mad! I have made many CT supplies using a twin sec transformer but I cannot seem to get this one to work.
I have a dual 55vac tranny and have joined the centre pair. when connected to the bridge I am only getting 112v between + & - and + & CT 56vdc and - & CT 56vdc. I was expecting around 75vdc per rail. What have I done wrong?

If you have two identical secondaries you can use them to make a bipolar DC supply in two ways:
1. Join them to make a CT secondary and use one bridge.
2. Leave them separate, use two bridges and join the DC outputs.
Any attempt to mix these two methods is likely to result in problems.

I did 1. as above, but connecting the outer secondaries to the bridge (the inner pair joined to make the CT) did not result in the 1.4 dc multiplier that I would have expected. I therefore assumed that I had done something wrong. The last time I built a Gainclone PS was about 10 years ago and I think I have gone silly

The measurements you are posting for analysis are NOT those of a future circuit but the current one.The schematic will be as
Yes, please show us the circuit. Not all the circuits which you do not intend to build, or the circuit which you will build. Just the circuit you have built and measured.
Please excuse my ignorance and lack of knowledge. I will make the circuit as previously posted and come back with the results. Apologies if I have wasted anyone's time.
