I've never pulled a Horstmann apart but would imagine it's along similar lines to the Greenbrook. It uses a capacitor as voltage dropper. Last one I repaired had a 474k (470nF) X2 capacitor that when I check was down to 197nF. Replaced the cap and all was well again. If you want me to strip it and see if I can repair then PM me. If you do replace the Horstmann PM mail me and I'll pay for the postage for you to send it to me so that I can play around with it.
 
Is it this one Tel
