Welcome mate, glad to see another Aussie join these forums!
I'm an Aussie myself and have been posting here since 2004 and I have a big collection of old electronic gear, mostly vintage TV cameras as it's my specialty but I also have some old TVs as well including a rare US imported 1947 Andrea VJ12 TV chassis with a radar tube for a screen, my collection can be seen on my site

Cheers
Troy
