What year was your Philco tube booket published? The 6L6 was developed by RCA in 1936 and Philco did not start using the glass version of the tube (6L6G) until mid-1937 (for the 1938 season). So, it would not appear in any tube manuals published before 1937.

As for substitutes, I don't think there were any substitutes for the 6L6/6L6G early on. Variants such as the KT66 and 5881 came later.

Dan Double conversion is using two IF converters instead of one. This improves the image response. morzh — 07:15 PM
