## Questions & Answers

**Q: Are these a suitable replacement for Chinese 6N1 tubes?**
A: No, the 6N1 tube is a 9-pin dual triode tube. GE 5654 is 7-pin pentodes. They are different types

**Q: Will these work in a yaqin ms-30l amp?**
A: Yes, these will work.

**Q: How do these compare to the Platinum grade riverstone tubes for 6J1s?**
A: Go with the Riverstone. I used the Riverstone and they are way better.
Warmer, bigger soundstage, no harshness

**Q: Will these work in a fosi T20 mini power amp?**
A: They work great for the T20 and sound much better than the 6J4 tubes that came with it. No doubt
