" stability of bias of KT88 in Xindak V30
Anyone know how often KT88 will drift over their life?I picked up a used Xindak V30 and suspected the tubes needed adjustment. After searching around for a while I found this post in their discussion forum:
The image points out the relevant resistors and trim pots to adjust, and seems to mention something about 0.5V, and 50mA, which is consistent with the 10 ohm value of these resistors based on ohms law."I think you need one **10 ohm, 5 watt resistor** to replace the number 4 resistor. note, the resistors could be 3 watt instead of 5 watt. Post a close up picture, I think I will be able to tell.
