Zenith 6D414 mentioned on ARF.

I'm not a member of ARF, but I follow a few of their threads.
I had a chance to get one, but I forgot to take it! That was the one with the bakelite chassis that supposedly been a embarrassment to the company!
One thing that was strange is that had an original 12SA7G. I didn't think one existed!
It turned out to be Zenith's version of the Vega.
BTW, I have a mid '50's Westinghouse bakelite chassis clock radio, but it isn't too bad to work on.
