After my meltdown at EMF, I needed a new tank capacitor. I decided to risk buying some Dawncap DTR series from AliExpress. The 0.44uF seems to be the most popular model, but I went for the 0.33uF 3kV instead, and was careful to use what looked like the Dawncap official store.
As I was in a bit of a hurry for Gaussfest I quickly made a plywood case with little thought to ventilation.
The front panel was made of plastic sheet (PVC?) as the plywood was too thick to give clearance for the connectors. These are 120 amp AMP Radsok connectors, also known as “Degson”.
Foam draughtproofing strip was used to stop the capacitors from rattling around, and the wooden case was painted black.
This capacitor is 10% bigger than the old one (0.33uF vs 0.3) but it seemed to perform exactly the same, no adjustments were needed to PLL frequency limits or primary tapping point.
