Hi Dennis,
I have the August 1956 issue of the Hammond transformer catalogue here in
front of me, & there are NO "model 2740" plate transformers listed in it at
all...
What they DO show are "X" mounted plate transformers with "type" numbers
listed from 710 to 733, and "tapped" plate transformers with "type" numbers
from 762-60 to 795-60, and "universal tapped primary & secondary" plate
transformers, with the "type" numbers of 757-60 & 767-60...
Nothing else --- at least not in THIS particular catalogue --- comes close
to matching the "type" number you reference.
Perhaps yours either pre-dates '56, or was manufactured sometime afterward.
In any event, I'm sorry I couldn't have been more helpful to you...
Good luck!

> Hello:
> I have a vintage Hammond Plate transformer Model 2740. It's a split
240vav primary and approximately 3500vac secondary. The core looks as if
its 3-4 kva. Wrote Hammond previously, but they didn't have any info on this
dated transformer. If anybody has the data for this transformer, I would
like to hear from you please. Will be away for a few days, so thanks in
advance.
