Most of the postwar sets using a tuning eye use the type with a band of light or a semicircle shaped pattern...these are 9-pin tubes like EM84. A lot of reel to reel's use the line type of indicator tube, too. Many old reel-to-reels used a 6E5 too which got little wear, so if you come across and old reel to reel you can borrow the 6E5 from it for a radio.
