That is effectively pre regulating. Technically sound, but a large drop times high constant current will produce heat also on the pre reg, plus you introduce complexity that will give a different subjective result since you are wrapping the super reg in a typical chip. I would much more prefer a CRC passive pre filter, with resistors of value and Wattage/sinking to drop properly. That rectified and filtered output has to go directly to the filter caps pads on the blue at +/-20V DCin. Maybe 39R 5W amongst two 4700uF made externally or by hacking the board. That would drop about 8V for each rail of a +/-200mA set CCS on a blue.
You can break the copper connections between + to + and - to - of blue's 4700uF pos and neg filter cap pairs and introduce a 39R 5W per rail between them underneath. With 8R2 5W set resistors where it says 10R 5W, will surely create an around +/-20VDC final DCin to the regs when using a 2x21VAC trafo. Use 35V caps, no less.

Yeah, I bought 3x blue boards & a mesmerize too. Why so many I can't say. I missed the GB for the Mes and so when blue came around I got a bit carried away. 
I've hacked one blue board to bits as you know.
Great project Salas, not least because you're here to hold our hand. How in hell do you speak such good English?

I have spent a year in Manchester before 20yrs. I guess I picked it up a bit there. Now, between the ''can you spare a fag mate?'' and ''ta love'' to explaining a CCS and a cascode it must have taken a miracle.
Was nice at the Hacienda though. Can't remember much more than Bassomatic and a constant thirst nonetheless.

The Hacienda Salas? I was probably there at the same time mate. Heady days... Mike Pickering and Graeme Park and yes very thirsty
Oh, and thanks for this info. I was hoping to use a spare 30VA 18-0-18 traffo just to get me going. This helps a lot.
Cheers

Plus Jon Dasilva and the chill outs in Subterranean with the New Order, or the pints in the Dry bumping on Shaun Ryder. Anti diva days.
Jon Dasilva was quality. Fair play you saw New Order, respect. I saw The Stone Roses there and once stood next to Tony Wilson for 10 mins before realizing who he was!
But do you remember the graffiti on Factory headquarters front from non signed bands? LOL.
P.S. That movie I saw once wasn't far BTW. http://www.imdb.com/title/tt0274309/

Amazing stuff! Have you seen the film about the Hacienda - 24 Hour Party People
Great film, by the way.
Guess what, I have "found" a whole bag of 10x BC550Cs in my box of delights, so the single reg RIAA shunt is on the road again. I'm getting 25.56v DC out and Vdrop across the 3K3 is 21.61v DC
Remind me how to calculate for a 28-30v supply will you...
By the way, this is with 1.7Vf leds.

I remember the size of the bloody bouncers!
Sorry folks, Salas and I heading down memory lane is diverting the thread a bit.
Good work Salas. Keep it up fella
Yes, I have added a link about that flick too.
3.978k in total. Add one in series to the 3k3 that will get it about there, or make some other new combination from paralleled ones, whatever.
