제가 쓰는 프로 장비인데 진공관 교체시 조정하라는 메뉴얼입니다.
대충은 알겠는데 좀 더 정확한 해석 좀 부탁드립니다.~~
뭘 어떻게 하라는 건지 정확히 알고 싶습니다.
그리고 5번에서 .05 volts로 맞추라는데 .05볼트라는게 0.5볼트인가요,0.05볼트인가요?
When replacing V1 (12AX7) in the STT-1, you must make an adjustment to the unit.
1. Let unit warm up for 20 minutes.
2. Turn the Vacuum Tube Gain pot full counter clockwise.
3. Place a DC volt meter from R85 to R88
(the ends of the resistors that are closest to the front of the unit.)
4. Adjust VR4 (near V1) to achieve minimum voltage. Should be near .05 volts or less.
5. Turn the Vacuum Tube Gain pot to full clockwise. The voltage may change.
Let it sit at full gain for 10 seconds or so and then turn back to minimum gain and using R4, null the voltage between R85 and R88.
Do this a few times and when it is balanced there should be not much change from low to full gain.
