Hi,

I'm restoring a 1949 Zenith porthole, model 28t926. When I say restoration, I mean everything. It was given to me for free and requires restoring the case too. My flyback tests bad on my Eico tester. Does anyone have an extra working one? Also, the other portholes I have, have an option to change the screen size, this set does not. Was this an option on early sets? All there is, is a momentary switch to light beginning prisms. I have the blonde set of knobs, but I need the dark red ones that match this set too.

Thanks,
Scott
