I have a 5-tube Canadian Marconi set with 12SA7 12SK7 12SQ7 35L6GT 35Z5GT
tube lineup from the factory, and this was definitely intended for local Canadian
market with 110-V line. I would have to check if it has a dropping resistor.
On the other hand, the sum is only 2% below 110 V (3*12.6+2*35), so it's no
big deal.
