I have a pair of original Cetron 572B's in my circa 1974 Yaesu FL2100-B amp. They still produce pretty close to 600W with 60W drive. I never run the amp over 500W out, don't need it. I've also used it in various RTTY contests at about 300W without any problems.

Will probably grab a set of RF Parts tubes in the near future for spares, but I don't think I'll ever need them.

Cetron 572B are the best tubes money can buy. The tubes last many years and some date back to the 1960s still producing full power output.

Unfortunately, the tubes have fallen out of production many years ago. I still find NOS available and are worth over $200 for the pair.
