The 6p3c-e is a great tube in the ST-70. I'm running them on my brother's ST-70 with Kevin's kit, sounds really good. Make sure you get the 6p3c-e version, with the coin base, the regular 6p3c doesn't sound very good in comparison. Don't worry about the voltage rating, the Russian specs are super conservative. I've heard of people running them with almost 600V on the plates. The 6p3c-e tubes in my brothers amps have been working fine for several years with about 440V on the plates. They sound really good when run at 21 watts dissipation. Highly recommended
