I bought my variable transformers at hamfests or flea markets, where they usually can be gotten at a good price.
Yes, connect the 6.3 V secondary in series with the hot side of the line. You connect the primary to the line and neutral. The phase will determine whether the secondary voltage adds or subtracts from the line voltage. If the voltage is higher than the AC input, just reverse the leads to either one of the windings.
You can put the transformer in a box with a line cord, fuse, and outlet, so any radios you plug in will see the reduced line voltage
