Mine definitely had white heatsink paste under the black bit.. stuck on the metal baseplate. I'm presuming that might not be included on the kits where you are bolting a metal sub-plate onto the existing non-electronic distributor base?
Is there anything one could do to improve heat dissipation on such units? i.e. that might not be done because it is labour intensive, but that we could do easily.

There has been much posted on this subject — my experience is with a Pos earth Powerspark baseplate fitted to a DK4A. The latter in good condition. This, with a red rotor arm, set me back about fifty quid in October 2016 when it was put on the car prior to a 3500 mile trip through Europe.
The car has now done over 5000 miles with this conversion and runs better than it ever did with points.

I was very happy indeed with the running of my Accuspark but I've bought two ignition kits direct from Hong Kong for fitting a UK Lucas 25D4 unit to a future car, the sensors being about 18 quid each. There was one kit on ebay for just over 15 quid... so that clearly is about trade price.
The key thing seems to be 'carry a spare' that you can easily and stresslessly fit when or if one decides to expire. But some seem to be remarkably problem-free.

Alastair’s (The Prisoner) unit worked, just not on his car - until he fitted a filter.
The Hall sensor is the part that fails - some immediately and some not yet! Carrying a spare is very sensible idea.
I have mentioned elsewhere potential cause and things to check before fitting one.
JonE - can you link to the units you mention above please? Also, are any positive earth?

Thank you Jon, much appreciated - I suspect they are all made of ice cream, some melt quicker, that’s all!
