Not really - Predicta compatible CRTs get snatched up quickly.

Are you sure you want a 12JP4? Remember it has no ion trap and will develop an ion burn. I'd suggest going with a 12QP4 to avoid this. 12LP4, 12KP4 or similar might be possible, but they have a different anode connector and are longer.
