Default Few more PCbs for AD797 HQMC phonostage for LOMc

I have few more PCbs for this phonostage.This is one of the best DIY phonostage for LOMC designed by Ak member Hypnotoad, also very cheap to build. Each Pcb would cost you $12+ $6 shipping by Registered post. Here is the thread AD797 Phono Stage Build and Help Desk Thread | Audiokarma Home Audio Stereo Discussion Forums

Sorry, Hypnotoad (designer )has not posted schematic anywhere. The PCb has all the values printed on it. Its a straightforward build. You will surely love it.

I will take two sets but am wondering what the difference is in the PS PCB shown vs the PCB's labelled as SPSU with C1 to C4 in a line at one side and Ch1 to Ch4 in a line on the other side.

PM on the way.

Hi
The SPS was small power supply works with 12V AC wallwart. The OPS power supply(shown here) uses 12-0-12 to 18-0-18 transformer intended to use with 3-4 preamps at a time. Both have adjustable power outputs. OPS has single as well as dual adjustable outputs.
You can see OPS at work here with many preamps:
