Hi Gary
Electrically, a 6H6 and 6H6G are identical. Philco put those shield bases in their 1938 models to prevent the use of RCA (metal) tubes. Nice, huh? But you have to remember, Philco and RCA were at odds with one another throughout the 1930s.
If you have a junk 1937 Philco chassis, you could switch the 1938 shield base to a 1937 type - they are made differently, so that metal and later GT tubes will fit inside them. I've had to do that before. When the shield is in place, no-one will know the difference. It will require removing the old tube socket rivets and then re-riveting afterward. But, I would think, anyone who can totally rebuild a 1937/38 Philco off-on-tone switch could easily re-rivet a tube shield base to a chassis!
Good luck, however you decide to proceed.
