As the title says, I'm after a 19" Mullard A47-26W A47-26W or an equivalent as long as it's got a fair amount of life in it.

The one that's in my A640-chassis Rediffusion is really tired and I think it's on borrowed time. It has woken up a bit but the emissions are showing as non-existent. Thought I'd put the feelers out whilst it's still working.

@wayned If you move the spring slightly I think you will find the CRT is actually an A47-26W, an alternative if you can find one is the Mazda CME1913. Sorry, can't help with either but hope you're successful obtaining a replacement.

Hi Wayne, have you considered CRT re-activation methods?

There is a non-destructive method described here.....

@pye625 yeah, I am going to do that at some point. I did increase the voltage to the heaters a small amount for a few hours and that did improve things but in case the worst happens (knowing my luck!) I would like a back up plan.
