6J1 Tube Preamplifier Kit Diy Vacuum pre amp board PRT-01A Review

Description:

6J1 is a side-by-side power cut-off pentode,on the past tube millivolt meter and other instrument-level equipment, you can see her small figure, enough to prove the stability of the tube, because the possession of a great, High, but the performance is not weak. Many old burns have played the tube and recognized the tube.
Feature:
PRT-01A using transistor connection, low distortion, good linearity, quiescent current set in 2.6MA, the whole class A working state.PRT-01A is designed to integrated board, DC filament power supply, high voltage with voltage regulator and electronic filter with direct streaking.
Filament part:
AC6-12V not less than 500MA (when more than 9VAC input, please note that the heat sink heat)
High pressure part:
AC200-240V, not less than 10MA
Special Note:
In order to reduce the high voltage part of the power supply resistance, this version is not designed to install the discharge resistance, so after the power off part of the high voltage part of the discharge is extremely slow, do not touch the high voltage part of the device
