VP Revolution 2 Speed Power Supply for the LP12
Upgrade your purchase with these options:
We were contacted recently by Mark Sears of VP, who supplies the excellent VP stylus DustBusters to us. Mark is an inveterate Linn LP12 tweaker and he was keen for Russ to have a listen to his newly-designed LP12 power supply.
The VP Revolution Power Supply is a high performance, two-speed supply designed to replace internal power supplies fitted to the LP12, such as the Valhalla and other after-market internal power supplies. As long as your LP12 is fitted with the original 24p motor, the VP Revolution can be fitted. We duly received our sample and Russ couldn’t wait to get his hands on it and put it through its paces. And the result? Russ loved it, finding it sounded natural and clear when installed on his own LP12.
I have an LP12 at home with a Valhalla power supply (albeit with my own upgrades to the original Linn design) and so I was sceptical whether this new supply would bring about an improvement.
Fitting was straight forward, and from the off it was clear that this supply was an upgrade. Bass was clearer and better defined; it went deeper and was more tuneful. The whole effect was to give a sound that was clearly better – it was more musical and delivered a more enjoyable performance.

We've produced a simple guide below showing how easy it is to fit the VP Revolution power supply.
Before undertaking any modification, please ensure you completely disconnect your LP12 from the mains supply and leave for 45 minutes for any current and voltage to discharge.
We take no responsibility for any damage caused by the miss-installation of the power supply. This guide is purely for reference purposes only. Your LP12 may look a little different to ours, but the method is the same.
To aid with the installation of the power supply an LP12 jig is extremely useful. Although an official jig is quite expensive it’s a good investment to make as it will help servicing and upgrading your LP12 much easier. There are however, plenty of DIY and innovative alternatives if you search online.
