6973 - 6CZ5

The 6973 is a legendary tube used commonly in Jukeboxes but also some guitar amplifiers. The 6CZ5 is a similar tube and is SOMETIMES a suitable substitute for 6973 but not always. The 6CZ5 has significantly lower plate voltage limits and pin 8 is different. The tall bottle version is said to be most similar to 6973.
