Hercules II Power Supply

Hi Fi World Magazine Review - October Issue

Adam Smith's Spinn Doctors Linn upgrade reviews.

Taking the Ethos of the Valhalla and improving upon it, Stamford Audio are able offer the Hercules II power supply for the LP12 which very handily, sits over the mountings already present on the Chassis. The Hercules II replaces the Valhalla board completely and can be fitted in s very short time, merely requiring the mains lead and motor wires to be disconnected and refitted to the new board once in place.

Also Supplied is the new on/off switch that replaces the LP12's original item,and this has two LEDs fitted rather than the one to show the selected speed as the Hercules II offers 33 and 45 rpm.

Even handier is the fact that both speeds are selected through this single button-from standby mode you simply press to switch on at 33 and light the red light, or press for 5 seconds to switch to 45 rpm and light the blue LED.

Manufactured in Hong Kong for Stamford Audio, the heart of theHercules II is a pair of low noise, high precision crystal oscillator circuits that have their frequencie divived to generate a clean AC sine wave which drives the motor at either 50HZ (for 33rpm) or 67.5 Hz (for 45rpm)

Sound Quality

The improvements made to the LP12 are evident even before the stylus hits the groove, as the motor seemed to be spinning much more smoothly once the Hercules II was warmed up and running.

Previously a hand on the top plate near the motor would pick up a very gentle vibration, but through the Hercules II there was none.

Sonically the changes were just as noticeable. Suddenly the hole that I had noticed in the middle of the soundstage was filled in putting vocalists and instruments in their proper place. Paul Desmond was now rock-solid centre-stage playing the saxophone on the Dave Brubeck Quartet's Take Five with the surrounding drums and double bass much more focused in terms of image stability.

The Hercules II also improved the bass end. Although not digging a great deal lower, the upper end of the low frequency spectrum was much tidier,improving the sense of pace,removing the rather flaccid nuture noted previously and generally tightening things up very well indeed.

All in all, the Hercules II kept the innate nature of the LP12 but made it sound much more confident. It also made an improvement over another earlier noted weakness, that of rather softer tracks. Where the Valhalla seemed to lose interest in this type of material, the Hercules II kept the atmosphere up and was able to tease small subleties out og the back ground.

Conclusion

For your money, you get improved soundstaging, increased 'confidence' to performance,better pace and switched 45rpm. Even if you are happy with your old valhalla'd LP12 and hadnt even thought of upgrading it, you mighted be surprised at the improvements a mere £170 investment will bring you. 

The Hercules II is universal so will work with 230/240 or 110 just by changing the fuse on the board

NO NEED TO CHANGE THE MOTOR!

HERCULES POWER SUPPLY FOR THE LINN LP 12 TURNTABLE

 

From STAMFORD AUDIO, here is the ORIGINAL Hercules II Power Supply for the Linn LP12 Sondek
Not to be confused with cheaper imitations!
  
CE rated; a hifi component in which you can be confident.
  
HiFi World (October 2007) stated that the Hercules gave the LP12 "improved soundstaging, increased 'confidence' to performance, better pace and switched 45rpm...  also improved the bass end", concluding that "Even if you are happy with your old Valhalla'd LP12 and hadn't even thought of upgrading it, you might be surprised at the improvements a mere £170 investment will bring you.".
 

The Hercules sits over the mountings already present on the chassis if you have a Valhalla (if you have an older, basic power supply, you need to obtain a cross brace to mount the board onto). The Hercules II replaces the Valhalla board completely and can be fitted in a very short time, merely requiring the mains lead and motor wires to be disconnected and refitted to the new board once in place. Very simple to install. Full instructions are provided.

The new on/off switch that replaces the LP12s original has two LEDs fitted rather than the one to show the selected speed as the Hercules II offers 33 and 45 rpm. Even handier is the fact that both speeds are selected through this single button - from standby mode you simply press to switch on at 33 and light the red light, or press for 5 seconds to switch to 45 rpm and light the blue LED.

Manufactured to a very high standard in Hong Kong for Stamford Audio, the heart of the Hercules II is a pair of low noise, high precision crystal oscillator circuits that have their frequencies divided to generate a clean AC sine wave which drives the motor at either 50HZ (for 33rpm) or 67.5 Hz (for 45rpm). Build quality is superb, using superb components resulting in an extremely reliable upgarde for your Linn LP12.

The Hercules II will work with 230/240v or 110v just by switching the fuse on the board to the correct housing.

NO NEED TO CHANGE THE MOTOR.

The Hercules II will also work with other Airpack/Premotec motored Turntables like the Rega and Thorens.
