As much as I like the Centurion, go for the Titan III. Why? The
3-500Z's put out by RF Parts and used in the Centurion just aren't as
stout as the GU-400B's used in a number of amps today. You're right -
replacement costs are about the same (altho the GU-400B's are actually
cheaper than RF Part's 3-500Z's), but you'll replace the 500Z's more
often. Most common failure? Grid to cathode short. Either way, you'll
have a good amp.
