Delco Wonderbar Mystery

[DavGoodlin]

Thanks Greg! I have about a dozen NOS 12AL8s and all the others.

These are the oddest tubes with only 12.6 on the plates and a "space-charge" grid 1, exclusive to car radios.

I recapped this radio last evening and now just need to plug in a new 12DV8 and 12AL8 to see what kind of noise it makes.

The owner told me that "wonderbar" was like the original seek function, I wonder how well it worked, since Delco seem to offer it only during the late 50s.

Paul, I will try the Beitmans and get the right file reader, since it appears quite helpful like NostalgiaAir. There are just too many holes in my Sams and OEM schematics coverage.
