Description:
Our store has rolled out FU-811 (FU-811J), and the old model has been discontinued. What is the difference between this new FU-811 tube and the old 811 tube?

1. In terms of performance, FU-811 tube has high transmitting power, high vacuum, and long life span. It is suitable for ultrashort wave physiotherapy equipment. If it is used in a tube amplifier, the FU-811 has a good sound, better sound permeability, and higher power.

2. The new one boasts better technology and more stable performance. The mercury in the new tube is full and bright, while the old tube has less mercury, so the new tube has a longer service life.

3. Appearance: FU-811's tube base is red wood base, while the old model is black. The mercury in the new model is full and brighter.
