There was a period of time where LGB Sound had Capacitors, both Andy Rush and myself had the Brown LGB Mallett with them. Was always amusing when lifting off the Track to have the Loco Hissing for a few minutes while carrying around using up the charge in the Capacitor. Was not aware that they would need a longish period of freshening up. Though both of ours were used on MTS somthat may be the reason that we never had the issues that Swed has. Now at least sorted. If all else fails read the Manual!
