EU Orders
As a result of Brexit, orders placed from the EU may now be liable for import VAT where the total value is over €22. Whether or not a charge is applied will be down to local customs in your country. I can only apologise for any additional costs, but nonetheless thank you for sticking with me - I really appreciate you supporting my work.

Health Update:
Unfortunately, having been slowly recovering from my ongoing back issues, I've been hit with a serious chest infection that has left very debilitated and I am once again back on strong medication. Frustratingly, it has been one issue after another over the past few months, and whilst my wonderful wife is still helping to keep orders going out of the door, I'm afraid I have a backlog of enquiries that I'm unable to progress through as quickly as I would hope. I will answer each and every one of them, but please accept my sincere apologies for any delays that you may be experiencing in getting a speedy response to your enquiry.

Diode Voltage Dropper Kit (Preassembled) for 6V CD/DVD Motor Conversion


In stock


If you’re using a 6V dc motor in your Lima or Hornby ringfield motor conversion, and you’re using DC control or a DCC decoder without CV5/CV6 functionality, you’ll need to consider a diode voltage dropper to protect the motor from over-voltage and current.

This brand new style of voltage dropper will drop around 1.5 volts, and is ideally suited for our LA2, HA2 and HA8 motor upgrade kits.

It features a specially-designed printed circuit board and is pre-assembled, saving you preparation time and hassle. It will reduce the voltage going to the motor by ~1.5v, adding protection to any 6V motor and helping to achieve a far more prototypical speed.

We also stock a a range of self-build voltage dropper kits to fit different installation situations and soldering skill levels (including our low-profile surface mount (SMD) components kit) and our through-hole components kit), and a special -3V pre-made volt dropper that’s a great match for our LA3B, LA5 & HA5 motor kits and it strongly recommended for those installations.

The kit comes with basic wiring instructions. Detailed instructions are available in our ringfield adaptor kit instructions booklet which is available via our website.
