I have just purchased a mint Linn Sondek, Ittok VII, Valhalla, Trampolin with a Grado Reference Platinum.
In 1983, I bought a new Linn LP12, removed the Valhalla board, ON/OFF switch and put them in an aluminum case. There was a slight improvement in sound. Please see scanned photo, left box.
Now, I am thinking of purchasing either the Hercules II from Stamford Audio or the Mose + Hercules board fully assembled and tested directly from Hong Kong.
How many of you are using any of those boards and how content are you with this mod?
Best regards,

I had a Hercules wired remotely from my lp12 for a while. It's not a bad thing, but not as good as Meldano's ac controller.
this one ?
Microprocessor Turntable PSU Set
I am looking for the schematic of the Hercules unit. Maybe this schematic exist online as PDF.
P.S.: There are a wide range of motor control units for synchronous motors, of those I know provide the topology of Dr. Fuß (sine wave oscillator based on SVF) best sonic results - go to post #12 under
Homebrew Motor Control Linn LP12 - Circuit Description wanted for Sine Wave Osc.
for the impressions while a listening test and #16 for the associated schematics.
I would be interested in how the difference is while listening against Meldano's ac controller is .

Hi, may someone able to help me,
I have a LP12 with Hercules PSU, it is work fine within a hour but after the motor not spin only flickering,
Not able to find the schematic and without the fault finding is not easy,

anywhere I had post a link with an overview incl. schematics of all known motor control units for synchronous motors such like Linn Axis, Valhalla, Lingo, Ariston and much more. Maybe the wanted schematic is also present there.
Don't publish the company under

Thanks there is "only" the original Linn not a Hercules from StamfordAudio,
