[Heathkit] O-12 power transformer

[tchesek]

I thought I could research an alternative but had no luck.  A Heathkit transformer cross reference shows that part number being used in the O-12 only.  The 1984 parts master file shows these specs for that part number: 1440MT43mA, 6.3CT3.A, 6.3NT.6A.  The two 6.3 volt outputs would be fairly easy to replace but the 1440 volt multitap would take some creativity.  I don't have an O-12 or manual so I don't know how many taps the 1440 winding has or what the specific voltages are for those taps but I picture a kludge of transformers to replace it.  Your quest for the unique original transformer is probably the best choice.

Good luck,
Tom K3TVC

      I have an O-12 which was given to me some time ago. It had 
probably been in storage for many years.  It ran OK for a few days and 
then the power transformer lost a winding.  I checked the filter caps, 
etc and they all seem OK so something else happened.  Anyway, I would 
like to find a replacement transformer. The handbook lists this as part 
number 54-26,  Please let me know if  you have one via private e-mail.
