Default GEC BT336 possible tube change

I'm looking to replace the original warn out picture tube in this set.
I believe has has a Gec 7601A. That infact is a MAZDA CME 1901
Looking at a 1970 MAZDA data book the 1901 has been superceaded to a CME1903s That cross references to a Mullard AW47-91 .
To cut a long story short i believe I have the Mullard version in a non working set that I would like to use assuming that one is not warn out..
Only other thing in the Mazda book it says the upgraded CME190 is for 300ma heater chains only .
Talking to a well known forum member the other day he tells me most tubes can by used as long as they will fit but I'm just checking before taking the plunge .
Thanks Andy
