Hello! I need a help!!
I would like to know how old are my output transformers.
One is "Stancor A-3823". Another is "Thordarson 24S33".
I have hardly tried to find out the age of trannys. However, I have
nerver had a decisive answer.

Does anyone have any idea?
If you do, Please let me know.

Thanks.

P.S. I have figured out that "Stancor A-3823" continued from early 60's
to 70's.
