My DCB1 has around 17v at the main filter capacitor. But bear in mind that you will need higher value capacitors, they are maybe too small for both the power amp and the preamp at the same time.
Reached that point, why tapping it from the main supply caps? Why not adding another bridge and filter capacitors to the trafo and supply it independant?
The advantage would be to take the supply from the shunt regulator. If it won't be possible, there is no advantage of taking it from the filter caps.

Read there how you can utilize a Hypno board as a higher power reg. On pages 2&3 Ian444 shows his take on powering a T-Amp with that and discusses his experiences. In short, he found it very worthwhile. Don't mix PSUS, IMO. Dedicate one to the T-Amp.

no.
Do I think the T-amp will benefit from any type of regulator? I would suggest not.
How about moving all the T-amp advice to a new thread?
I don't know, I haven't read very much about T-amps. Is sure has a different topology than what I am used to, so you should read elsewhere about T-amps powered by regulators, and their performance.

I am probably late to join this group buy as I have just discovered this thread. I need some time to read and understand more about the details. Before that it probably help by asking a quick question to Tea-Bag that if I still have chance to join the group to buy two Mezmerize boards and four Hypnotize basic boards. I know the two Mezmerize boards will be good for two channels RCA inputs. I am not sure if the four Hypnotize boards will be good for me to build another stereo with balanced input.

Hi arrow,
The Hypnotize boards can build a stereo channel. The same with a mesmerize except it has relay inputs. The mesmerize is out of production, the hypnotize there is a sign up list for under my signature. The mesmerize we might do a another run if the interest for enough boards is there. Likely the production of them will cease.
The new hypnotize has been hinted about, but is similiar to old hypnotize, with more spacing for more and larger caps, to-220 diodes, uses 2oz copper, and more importantly will be blue in color. You can read more about the older types on my blog.
Salas and I will update more soon about the newer Hypnotize design.

Dear Tea-Bag,
Thanks for the quick reply. The more I read this thread, the more I like both Hypnotize and Mesmerize. The Mesmerize board on its own is more like a completed pre-amp (unity gain) with multiple switches for inputs. The Hypnotize can serve not only for B1 but also other uses for small current applications.
It sounds good with the new 'Blue Edition' Hypnotize. Can I sign up for six of those boards? I am going to use them not only for B1 but also to upgrade the power supply of my D/A and active crossovers. Please let me know if I can join the new group buy?
thanks

Hi, things have changed but the AC wiring crossing the TO220 diodes is not pretty. That Phoenix connector should have moved to the side long ago. Still 2 jumpers and a narrow spot for the ground tracks ( too picky, I know ).
Just a thought: when all MOSFETs are brought to one side mounting them will be more easy on a heatsink or cabinet/case. It will leave possibilities for the AC wiring too. In my eyes the layout is somewhat less optimal/tidy than before, I am sorry to say so. Or at least I don't see many advantages over the old boards except for the caps and the TO220 diodes. I won't start about the color of the board ...
Maybe the marketing department should have advised to design just a general purpose shunt supply board from xx mA to xx A without the buffer part
Omitting the buffer part, putting all MOSFETs to one side and using a 6 pin Phoenix ( 2 x +, 2 x - and 2 x GND ) at the power output for feeding more than 1 circuit certainly would be nice additions. The board would then be a truly versatile shunt supply PCB.

I thought about running the wires in via the middle of it.
I am not sure why it makes any difference, being this is where normally Ac/Dc takes place. I get no hum or nothing with even headphones on, so it's promising to me.
Time to build another case, the Nichicon FG caps are a bit taller than the other's I was using. I've got a IE tranny I am considering using as well.
I've heard substantial differences swapping resistors on the DCB1 portion of the circuit, so I went all out and purchased some nice one's. I had a $100 gift card from work, so i thought I would blow it on parts.
