Top 5 Positive Customer Reviews for 6j1 amp
Very good price/performance quality thanks to the dual power supply, way better than other similar products. The downside is that you need to have a good 18v transformer with dual wingdings in the secondary.
The sound is good. There is no noise. The sound can be adjusted by vacuum tube and tone control. There is no power. It is better for the power amplifier to be connected to have a higher output.
