PRODUCTS - With over forty years of electronic design and manufacturing experience, mostly in the audio industry, I still love taking on challenges and winning! For me, designing something and seeing it through to a commercial product, is as creative as writing and producing in the studio. Under this category,  you can browse through the things I make to help musicians, producers and engineers, along the way. 🙂

SERVICES (Technical) - Don't let the fact that you're unable to install one of my systems into your beloved piece of vintage equipment scare you off! I'm more than happy to do that for you. I also repair and  service studio and live performance gear as well as renovate vintage synthesisers, signal processors and guitar amps.

SERVICES (Creative) - I've been involved with studio and live music production, since 1985. It's my passion and I have a huge wealth of knowledge and experience. Being a musician myself, I'm able to connect with my clients while I make magic things happen. I'm also a keen photographer, website and graphics designer. If you think I can be of assistance, please do check out this category.

UPCYCLED AUDIO - My project for 2023, Upcycled Audio offers vintage equipment that's been renovated and / or upgraded with a view to deliver classic quality performance with modern convenience. You can read more about it here.

MARSHALL JMP-1 STUFF - Putting all my bits 'n' pieces for the Marshall JMP-1 into one place will hopefully make things a little easier for fans of this legendary MIDI valve pre-amp.

Cheetah MS6 Power Supply

In stock
Product Details

Housed in a robust, die-cast steel enclosure, my Cheetah MS6 external power supply is a solidly built, reliable power plant which replaces the exceedingly unreliable internal power supply of this instrument.

The whole upgrade includes converting the battery charging circuit and then installing a CR123 lithium battery in place of the rather dated Ni-MH memory back-up battery.

A more substantial heatsink is also installed. Properly designed, it ensures that the regulators run at a non-cooking temperature (!), thereby increasing their reliability and life-span.

Here's what's included:

  • Preliminary check of your MS6.
  • Taking apart and dismantling the entire unit.
  • Removing redundant power supply components.
  • Removing back-up battery and associated components.
  • Preparing and delivering metalwork of external enclosure and MS6 chassis for drilling.
  • Building external power supply into steel enclosure and custom power cable.
  • Installing custom heatsink.
  • Modifying the battery back-up circuit and installing the new lithium battery.
  • And of course, reassembling and then testing the unit.

I cannot test your MS6 if the original power supply in your unit has already failed. If there are other issues that become apparent once power can safely be applied, resolving them may incur further costs.

More information is available here.

I will need your MS6 so please only buy this if you are prepared to send me your synth module.

NOTE: If you purchase this option please contact me to confirm shipping arrangements.


Annoyingly, my shopping cart software displays shipping information after you’ve confirmed your payment option. I’m trying to get this changed as I believe that customers should always know exactly what they’re paying. Of course, I have no control over import duties but I try my best to give clear, concise information.

I therefore maintain a ‘Shipping Prices’ page and visitors to my website who are interested in buying stuff, have the opportunity to check shipping costs to their country / region.

My shipping costs are calculated on item value and not weight as everything is insured.
