Hi Siberia,
you mean the turntable ?
I've just restored my beloved Thorens TD125Mk2, bought it some 35 years ago..
The motor wasn't spinning anymore, it was enough to replace a couple of 1000uF caps,
a common fault with this table.
My plan is to build a new plinth and replace the old tonearm with a Jelco 750, and maybe a Dynavector cartridge in place of the venerable Stanton 681.

I've certainly meant TT, but have no idea why I wrote Tx. Thanks for reply.

I do not see an answer. In the store I only see Mesmerize boards. What about pdf of boards to make my own? I have seen a variety in different posts, but am not sure which pdf design is the same as the hypnotize boards.

OK, I shanghaied this quote to post my question.
I am thinking of using this design for both a pre-amp and a crossover based on the B-1 topology, so I am looking at powering about 10 B-1 'modules' per side. If a complete B-1 draws 20mA (stereo), then I should be drawing about 200mA. To be safe I should double that and design for 400mA, yes? Also, I have a good source of pure DC @ 50V. With a voltage divider I can get +/- 25VDC. What happens if I put 25V in for 10V out (instead of +7V)? Should I use a series regulator first to drop V to 17 or so?
Thanks for the help.

Yes, double current capacity is good. With 15V Vin-Vout dif VS 7V you get more dissipation on the CCS MOSFET but better CCS PSRR frequency because the MOSFET levels out for capacitive parasitics at that VDS. There is the hot-rod Hypnotize DCB1 successor board and the BIB regulator board still in periodic circulation that you can use.

I do not see them in the store. Where/how do I get them? Is there a 'sign up'?
