Well the set is, um, set for 220V. I'm having trouble tracing where the current goes through that hairball of a voltage switch, but it seems like when it's in the 220V position the wire from pin 14 could simply bypass the capacitor, and the power supply then works like a normal full-wave rectifier? In this set C140 has vented its spleen all over the place, so I wanted to replace it but maybe it's easier to just disconnect it since the TV will never see 120V.
As an aside this is a pretty cool TV! It's unlike any American designs, but cool looking, and easy to service - you just have to unplug the CRT, yoke, and speaker, then remove two screws and the whole chassis just slides out into your lap. And it has, or had, a glossy laquer cabinet and big honkin speaker just like the Philips radios of the time. This one has some curious characteristics: buttons on the front that switch in and out high-and-low-pass filters in the video section, not sure what they're for, and it has a VHF-only tuner with no extra position between 13 and 2, even though it was sold back when they had already started the transition to UHF-only.

Jeffrey there are tons of those step-down transformers here, nearly all of them in cool midcentury bakelite cabinets, that can be bought for pennies. My Predicta came with one, and I have a couple more.
