Who made the best/worse tube radios

[mr_fixer]

The worst radio i ever had, I think it was a Philco. But it was only the ones that used Loctal tubes. A loctal tube has a aluminium base with a locking pin, the force required to remove the tube would most likely break the socket. I'm sure other companies used loctal tubes but the Philco was the first and last that I ever owned that had any. Logan
