Model Rail (Heljan) British Rail Class 11 shunter revisited part 2

I am in the process of fitting ‘GoldCaps’ Energy Storage Capacitors to try to resolve the issue of stalling. This was the response from John at youchoos; “The simplest stay-alive to add to the MS581 is a pair of mini GoldCaps, connected in series.  The MS581 is designed to take those directly with no additional circuitry... has to be exactly 2 of the GoldCaps , no less, no more, to get the correct voltage (around 5V).”  I ordered the following KIT-YC1FGOLDCAP6 - 6x Mini GoldCaps 2.7V 1F. They arrived this morning two were joined in series and wrapped in Kapton tape. Then I set about modifying the control desk in the cab to accept the capacitors. Basically pop off the control desk it is held in place by two moulded pins and glue 40 thou strips of plastic strip on the mating faces repaint matt black and cut a slot in the bulkhead for the cables.  After testing on the rolling road what a difference no more stalling or glitch sound well worth the effort.
