Welcome to the Strathpeffer Junction shop. UK shipping for OO Gauge ringfield adaptor kit orders is £2.99, irrespective of how many are purchased. We also ship to Ireland, mainland Europe, USA, Canada, Australia and New Zealand (postage to the USA has regrettably doubled in price due to the US government's new tariffs).

Dispatch Schedule
Like most people, we had hoped that 2021 would herald in move back towards 'normal', but once again we are subject to a lockdown and access to shops and services is limited. We will have to stick to our twice weekly (Tuesday & Friday) dispatch schedule for most orders for the time being, however due to the size of the packaging required for O gauge motor kits, snow plough weights kits or mugs, we can only use a post office counter and, as we are reliant on a mobile post office for that service (and it only comes to our village once per week), we regret that orders including any of those items can only be despatched on Tuesdays at 12.30pm. As ever, thank you indeed for your customer, support and understanding.

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.

Pre-made PCB Diode Voltage Dropper (for 6V CD/DVD Motor Conversion)

£4.55

In stock

Description

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 new and improved pre-assembled voltage dropper will drop around 3 volts, which is twice the value of our other kits and is particularly suited to higher speed 6V motors.

It features a specially-designed printed circuit board and is pre-assembled, saving you preparation time and hassle, and will reduce the voltage going to the motor by ~3v, adding substantial protection to any 6V motor and helping to achieve a far more prototypical speed.

We also stock a a range of ~1.5V voltage dropper kits, which may be better suited to slower motors: our pre-assembled surface-mount diode dropper kit (DD1), saving you time and effort soldering small components, low-profile surface mount (SMD) components kit (DD2) and our through-hole components kit (DD3).

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