Nixie ·Nixie
Cold-cathode numeric or character indicator cross-referenced by a German comparison catalog to RFT Z5900M. The source warns that comparable types may not be identical, and no complete Z5900M electrical table is provided for reliable rating transfer.
B5855 is a cold-cathode numeric or character indicator tube. The supplied German comparison catalog maps it to RFT type Z5900M, while also warning that listed comparable tubes are not necessarily identical. Because Z5900M is not included in the supplied electrical-data tables, no unverified electrical values were inferred.
