Portholes on eBay

[Down Under]

Hi guys,

I notice there are two Portholes on eBay, which I'm guessing is rare. Out of curiosity, what are these sets like to work on? And how do they perform in terms of reliability? I'd love to have one, as they're a real show stopper. But I have to think about getting spare parts if something unique like a flyback fails, unless it can be rewound. Difficult enough to source in the US, probably impossible for me in AUS. You read about how some brands/models have their various issues, and I wonder what stories are out there regarding these TVs. Also of course the CRT. Do any of the Portholes use metal CRTs? I've heard that they can lose vacuum eventually at the metal/glass seal. All info appreciated.

Cheers,

Adam
