Very cool, well done

agreed, these calculators are to get you in the ballpark and in safe ranges. actual in-circuit testing is what is best for really optimizing tube bias. Throw a volt meter across the cathode resistor and measure the voltage drop with the amp feed by no signal, divide the voltage drop by the actual me...

got a schematic you could post?

Nothing I worry about but I also don't leave tube amps on when I'm not in the room.

I only wish I had the time to do this type stuff. one day when I retire...

Now that I have the covid vaccine and things are opening up, work has me traveling almost every week. Sorry for the impact to video making.

SUper clean. Looks like a router we made at work

Love it!

Very nice
