I like that kind of dial too.  |
That's what one of the semi readable schematics pasted on the case bottom re: tube layout. But there are 2 tube line ups. Mine has the ballast tube in the 5 tube line up. 2 of my tubes are unreadable the others are 43,25Z5 and 185r8 which is not listed on the line up. And it does have a choke plus the field coil.
