A 26K primary in the output transformer.

Today I received my speakers and since the output transformer is shot, I thought to re-use the transformer from that speaker that was in (it is non-Philco and I do not know what it is. The size kinda fits).
Keep in mind, it works.

Now I decided to look what primary DC resistance is there, since I need about 400 Ohm DC for the primary (and 7.6K impedance). First I thought I was measuring wrong points, so I unwrapped the electric tape and measured right on the transformer wires.
26K. Have you ever seen anything like it? 26 kiloOhms of DC resistance in the primary. Not the total impedance - just the sheer DC. Wow. Live and...gape.
