Nah, that's just tube microphonics. They aren't particularly predicatable, and not indicative of any associated issue.

81V is plenty close to 75V, that indicates proper operation.

Paul, just for clarification, with the Speedball are the same +/- 15% ranges applicable?

as imbalance is same with all volume levels volume pot won't cause it. So what can cause this?

There is some variation in this voltage, as is mentioned in the manual. This voltage will rarely be exactly 75V. This is normal.

Even as long as I have been building, I measure resistances before I place/solder them.
It is just a good idea. Sometimes Blue looks like the Violet in the color codes.
