Here's the Radio Shack product I've used for many years ignition amplifiers on Volvos and German motorcycles, both Bosch systems: Radio Shack Heat Sink Compound (Grease), PN 276-1372. It's $2.99 a tube, enough to last years. Heat is the enemy of this part, and the compound helps wick away heat to the aluminum heat sink base. Cleaning the heat-transfer face and applying a thin film is good maintenance every year or two. Don't overtighten the amplifier after applying fresh compound, it squeezes it out and reduces effectiveness. In this case, Mr. Starkie did the right thing but just happened to have a failure.
