274B is very similar with 5U4G and 5Z3P, which can be replaced by each other in many cases. In some cases, you may be able to use 274B to replace a 5AR4. Please always check with your amplifier about tube substitution in case you accidentally damage your precious amplifier or the newly acquired tube. Such damage is NOT covered by tube warranty and tube cannot be replaced.
