ECC31 tubes in 6SN7 slots of Line Magnetic amp. Possible?

I own a 508IA and the official word is ECC31 tubes aren't supported but I'm wondering if anybody tried their hand anyway at using ECC31s in the 6SN7 slots of their Line Magnetic amp and if so, what was the result?

You should try the 6f8g w/adaptor should work perfectly. I recommend the round plate, best sounding 6f8g.
