Recently, lighting struck my house and blew out the primary side of
the main power transformer in my UNIDEN 3100 cordless phone.  I want
to replace it, however, I haven't been able to determine the secondary
voltage rating.  The transformer is not marked, and I've had no luck finding
circuit diagrams for this beast.

I'm writing to ask if anyone has a similar model, and either knows the
secondary voltage rating, or might be willing to measure this voltage
on their working phone.

I also noticed that this phone has a jack on the base unit for using
a dc power source.  Does anyone know what voltage is required?

thanks in advance,
