Hi,
Can you give me more information on the 6j4+6p6p+6z5p HiFi Tube Preamplifier Kit? Do you have a BOM and information about distortion, noise, gain, volume control tracking, and power consumption?

Thanks.

Hi CC43fan:
here's the schematic for your reference:

The performance is largely depend on how well it is built.

Let's assume it's built well, can you provide me with the info I requested?

Thanks.

Tested with our preamp:
The distortion is less than 0.6% from 100 to 10KHz
Power consumption is about 60W. The transformer is 100W.
SNR: 88dB
Gain: about 10dB. could be adjustable by change value of feedback resistor

Are the 6J4's in fact Soviet 6J4P's?

No. they are different in shape and difference in electrical characters.
