I bought 11 TVs (counting the Portacolor without a CRT), a Reel to Reel tape deck (I have a few, but none that can handle the 15" reels like this one), and traded away two sets (though taking the Quasar was a condition of the trade) I took to the meet. I made exactly 0 cash sales.
Here are the pictures.
All show signs of life except for the hollow Portacolor, the 7" Admiral, the 10" RCA, and the little Sony.
The little Panasonic with no power up on the screen I quickly fixed to up 90% working, yesterday. The symptom described instantly made me think open series string filament, and I was right!...Sort of. One of the tuner tubes was completely missing. After finding one in my stocks it powers up and is just fine save for 1/3 vertical under-scan at the bottom, and some mild vertical fold over. I'll try and get it done tonight.
