[Hallicrafters] Small isolation transformers

[Horace W. Hall]

I have come across some small isolation transformers that can be used to
make those transformerless sets (like the S-38 series) safer to operate.
They are from 30 to 50 watts, made by Hobart and by Triad. They are the
small E-I frame style transfomers, resembling small filament transformers.
Physical sizes are about 2.5 inches square with the mounting holes about
3&1/8 inches apart. They all appear to be surplus stock from somewhere, not
brand spanking new, but apparently never used. It looks like they might be
a little easier to mount inside a chassis than those Fair Radio cylindrical
transformers (the ones with 4-hole mounting). The ones with prices on were
around $9. Let me know if anyone needs some of these.
