I'm sure your right, Jeffrey, but the transformer in my Regentone TR20 was showing no visible sign of distress
at the time when the Visconol was leaking the EHT to ground. The HVR2 on the other hand was giving a most impressive light show. It would appear though that the EHT winding had sustained hidden damage, as it later (some considerable time after having substituted a non-leaky EHT capacitor) gave the sort of firework display described earlier - resulting in a back voltage from the capacitor that (as I understand it) vaporised the cathode of the HVR2.
