Mains EHT on my Baird T18 is too low (2kv ish) - should be nearer 5...so given its a simple circuit it is either the transformer, the HV cap or the HVR2 rectifier...the tranny is running cool so hopefully is OK so that leaves the cap and rectifier...given my respect for mains EHT any comment would be greatly appreciated before I start to investigate!!
Could the rectifier suddenly lose emission or is the cap the more likely culprit?
Grateful for any thoughts,

Trevor.
