User experience

0 0

Users find a 5751 tube swap in place of a 12AX7 in V2 might not be ideal due to differences in transconductance and plate resistance, though it's safe to try.

Users report that a low impedance reading on the speaker, such as 1.6 ohms instead of the expected 16 ohms, can indicate issues affecting volume and sound quality.
