It's up to you what you do to your own radio but why change the EBL31 if the set is working OK? The EBL1 is electrically the same so can be fitted with an Octal base but why go to all that trouble (and have to change the top-cap as well) if the existing EBL31 is OK?. The EF39's do commonly lose their out screening and I usually just wrap some tinfoil around them rather than fitting a new valve. OK it doesn't look very professional but they are hidden from sight when the set is in use. Valves are a finite source and I don't change them for new ones unless it's absolutely necessary.
