Sounds like your transformer is saturating; common problem with small magnetics.
I used an LPR6235-123 from Coilcraft in my wristwatch. They sell to end-users in small quantities, which is nice. Even though it only ran for 7 seconds at a time, it still overheated at 7mA load but it's a possible option for you at 2mA. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
