Yep. It is a light version of Philco 20.
I guess it was soon after the 24 tube appeared on the market and everyone started using it.
Other than one less 24 tube and the 45 SE vs 2x71A P-P output.
There is a little bit of difference in using the tubes: 20 has the 3rd 24A as the tuned amp-detector (plate detector) and the 27 is the interstage driver; in Gloritone both 24 are RF stages and the 27 is both the detector and the interstage driver.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
